Custom App Updation in Android Implementing a Custom App Update Mechanism in AndroidIntroductionKeeping our Android app up to date is crucial for ensuring security, stability, and new features for users. While Google Play provides an in-app update mechanism, some developers prefer a custom solution—especially for enterprise apps, private distributions, or apps that aren't published on the Play Store.In this blog, i will walk throughimplementing a custom app update mechanism in Android that checks for updates, downloads the latest APK, and installs it seamlessly.Key Features of Our Custom Update MechanismChecks for UpdatesCompare the installed app version with the latest available version.Fetches update details from a remote server.Prompts the UserDisplays an update dialog with "Update Now" and "Later" options.Dismisses automatically after 10 seconds if no action is taken.Downloads the Latest APKUsesDownloadManager to download the APK.Stores the APK securely in app-specific storage.Installs the UpdateUsesFileProvider to securely install the APK.HandlesPendingIntent requirements for Android 12+Step-by-Step Implementation1. Checking for UpdatesBefore downloading the new version, we compare the installed app version with the latest version available on the server.private fun checkForUpdateAndNavigate(versionName: String) {val latestVersion = getLatestVersionFromServer() // Fetch from APIval downloadUrl = getDownloadUrlFromServer()if (isNewVersionAvailable(versionName, latestVersion)) {showUpdateDialog(downloadUrl)} else {navigateToNextScreen()}}private fun isNewVersionAvailable(currentVersion: String, latestVersion: String): Boolean {return currentVersion < latestVersion}2. Displaying an Update PromptWe display an update dialog usingDialogFragment. Users can choose to update immediately or later.class UpdateDialogFragment(private val downloadUrl: String) : DialogFragment() {override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {return AlertDialog.Builder(requireContext()).setTitle("Update Available").setMessage("A new version is available. Update now?").setPositiveButton("Update Now") { _, _ -> downloadAndInstallApk(downloadUrl) }.setNegativeButton("Later", null).create()}}3. Downloading the APK SecurelyWe useDownloadManager to download the APK to the app's private storage.private fun downloadAndInstallApk(downloadUrl: String) {val fileName = "my_app_update.apk"val file = File(getExternalFilesDir(null), fileName)if (file.exists()) file.delete()val request = DownloadManager.Request(Uri.parse(downloadUrl)).apply {setTitle("Downloading Update")setDescription("Please wait...")setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE)setDestinationUri(Uri.fromFile(file))}val downloadManager = getSystemService(Context.DOWNLOAD_SERVICE) as DownloadManagerval downloadId = downloadManager.enqueue(request)downloadReceiver = object : BroadcastReceiver() {override fun onReceive(context: Context?, intent: Intent?) {val id = intent?.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1)if (id == downloadId) {if (file.exists()) installApk(file)else showToast("Download failed.")}}}registerReceiver(downloadReceiver, IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE}}4. Installing the APK UsingFileProviderTo securely install the APK, we use acontent:// URI instead of a file path.private fun installApk(file: File) {val uri = FileProvider.getUriForFile(this, "${packageName}.provider", file)val intent = Intent(Intent.ACTION_VIEW).apply {setDataAndType(uri, "application/vnd.android.package-archive")flags = Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_ACTIVITY_NEW_TASK}startActivity(intent)}Ensure you define theFileProvider inAndroidManifest.xml:<providerandroid:name="androidx.core.content.FileProvider"android:authorities="your.package.name.provider"android:grantUriPermissions="true"android:exported="false"><meta-dataandroid:name="android.support.FILE_PROVIDER_PATHS"android:resource="@xml/file_paths" /></provider>Createres/xml/file_paths.xml:<paths><external-files-path name="update_apk" path="."/></paths>5. Handling Android 12+ PendingIntent RestrictionsAndroid 12+ requiresPendingIntent.FLAG_MUTABLE orFLAG_IMMUTABLE.val pendingIntent = PendingIntent.getBroadcast(this, 0, Intent(DownloadManager.ACTION_DOWNLOAD_COMPLETE),PendingIntent.FLAG_UPDATE_CURRENT or PendingIntent.FLAG_IMMUTABLE)Next StepsImplement background updates for a more seamless experience.Add progress indicators for the update download.Encrypt APK downloads for added security.ConclusionImplementing a custom app update mechanism ensures better control over app distribution and version management. Our approach is: ✔Secure (usesFileProvider) ✔Compatible (supports Android 12+ restrictions) ✔User-Friendly (provides update prompts and background installation)If you have any questions or need further improvements, feel free to reach out!

Building Kotlin Libraries with Gradle Building Kotlin Libraries with Gradle: A Comprehensive GuideThis guide demonstrates how to create a Kotlin library with Gradle using gradle init. You can follow the guide step-by-step to create a new project from scratch or download the complete sample project using the links above.What you'll buildYou'll generate a Kotlin library that follows Gradle's conventions.What you'll needA text editor or IDE - for example IntelliJ IDEAA Java Development Kit (JDK), version 8 or higher - for example AdoptOpenJDKThe latest Gradle distributionCreate a project folderGradle comes with a built-in task, called init, that initializes a new Gradle project in an empty folder. The init task uses the (also built-in) wrapper task to create a Gradle wrapper script, gradlew.The first step is to create a folder for the new project and change directory into it.$ mkdir demo $ cd demoRun the init taskFrom inside the new project directory, run the init task using the following command in a terminal: gradle init. When prompted, select the 2: library project type and 2: Kotlin as the implementation language. Next you can choose the DSL for writing buildscripts - 1 : Kotlin or 2: Groovy. For the other questions, press enter to use the default values.The output will look like this:$ gradle init Select type of build to generate: 1: Application 2: Library 3: Gradle plugin 4: Basic (build structure only) Enter selection (default: Application) [1..4] 2 Select implementation language: 1: Java 2: Kotlin 3: Groovy 4: Scala 5: C++ 6: Swift Enter selection (default: Java) [1..6] 2 Enter target Java version (min: 7, default: 21): Project name (default: demo): Select application structure: 1: Single application project 2: Application and library project Enter selection (default: Single application project) [1..2] 1 Select build script DSL: 1: Kotlin 2: Groovy Enter selection (default: Kotlin) [1..2] Select test framework: 1: JUnit 4 2: TestNG 3: Spock 4: JUnit Jupiter Enter selection (default: JUnit Jupiter) [1..4] Generate build using new APIs and behavior (some features may change in the next minor release)? (default: no) [yes, no] BUILD SUCCESSFUL 1 actionable task: 1 executedThe init task generates the new project with the following structure:├── gradle │ ├── libs.versions.toml │ └── wrapper │ ├── gradle-wrapper.jar │ └── gradle-wrapper.properties ├── gradlew ├── gradlew.bat ├── settings.gradle.kts └── lib ├── build.gradle.kts └── src ├── main │ └── kotlin │ └── demo │ └── Library.kt └── test └── kotlin └── demo └── LibraryTest.ktThe file src/main/kotlin/demo/Library.kt is shown here:Generated src/main/kotlin/demo/Library.kt/* * This source file was generated by the Gradle 'init' task */ package demo class Library { fun someLibraryMethod(): Boolean { return true } }The generated test, src/test/kotlin/demo/Library.kt is shown next:Generated src/test/kotlin/demo/LibraryTest.kt/* * This source file was generated by the Gradle 'init' task */ package demo import kotlin.test.Test import kotlin.test.assertTrue class LibraryTest { @Test fun someLibraryMethodReturnsTrue() { val classUnderTest = Library() assertTrue(classUnderTest.someLibraryMethod(), "someLibraryMethod should return 'true'") } }The generated test class has a single kotlin.test test. The test instantiates the Library class, invokes a method on it, and checks that it returns the expected value.More information about the features the java-library plugin adds to any JVM library project, such as API and implementation separation, can be found in the Java Library Plugin documentation.Assemble the library JARTo build the project, run the build task. You can use the regular gradle command, but when a project includes a wrapper script, it is considered good form to use it instead. $ ./gradlew build BUILD SUCCESSFUL in 0s 5 actionable tasks: 5 executedThe first time you run the wrapper script, gradlew, there may be a delay while that version of gradle is downloaded and stored locally in your ~/.gradle/wrapper/dists folder.The first time you run the build, Gradle will check whether or not you already have the required dependencies in your cache under your ~/.gradle directory. If not, the libraries will be downloaded and stored there. The next time you run the build, the cached versions will be used. The build task compiles the classes, runs the tests, and generates a test report.You can view the test report by opening the HTML output file, located at lib/build/reports/tests/test/index.html.You can find your newly packaged JAR file in the lib/build/libs directory with the name lib.jar. Verify that the archive is valid by running the following command:$ jar tf lib/build/libs/lib.jar META-INF/ META-INF/MANIFEST.MF lib/ lib/Library.classYou should see the required manifest file —MANIFEST.MF— and the compiled Library class.All of this happens without any additional configuration in the build script because Gradle's java-library plugin assumes your project sources are arranged in a conventional project layout. You can customize the project layout if you wish as described in the user manual.Congratulations, you have just completed the first step of creating a Kotlin library! You can now customize this to your own project needs.Customize the library JARYou will often want the name of the JAR file to include the library version. This is achieved by setting a top-level version property in the build script:KotlinGroovybuild.gradle.ktsversion = "0.1.0"Next to the version, other important identity properties of a library are it's name and group. The name is directly derived from the subproject name that represents the library. It's lib in the example so you probably want to adjust it by changing the name of the lib folder and the corresponding include(…) statement in the settings.gradle(.kts) file. The group is used to give your library full coordinates when published. You can define it directly in the build script by setting the group property similar to how you set the version (shown above).Now run the jar task:$ ./gradlew jar BUILD SUCCESSFUL 2 actionable tasks: 1 executed, 1 up-to-dateYou'll notice that the resulting JAR file at lib/build/libs/lib-0.1.0.jar contains the version as expected.Another common requirement is customizing the manifest file, typically by adding one or more attributes. Let's include the library name and version in the manifest file by configuring the jar task. Add the following to the end of your build script:KotlinGroovybuild.gradle.ktstasks.jar { manifest { attributes(mapOf("Implementation-Title" to project.name, "Implementation-Version" to project.version)) } }To confirm that these changes work as expected, run the jar task again, and this time also unpack the manifest file from the JAR:$ ./gradlew jar $ jar xf lib/build/libs/lib-0.1.0.jar META-INF/MANIFEST.MFNow view the contents of the META-INF/MANIFEST.MF file and you should see the following:META-INF/MANIFEST.MFManifest-Version: 1.0 Implementation-Title: lib Implementation-Version: 0.1.0Generating Sources JARYou can easily generate a sources JAR for your library:KotlinGroovybuild.gradle.ktsjava { withSourcesJar() }The additional JAR will be produced as part of the assemble or build lifecycle tasks and will be part of the publication. The resulting file is found in lib/build/libs, with a name using the conventional classifier -sources.Publish a Build ScanThe best way to learn more about what your build is doing behind the scenes, is to publish a build scan. To do so, just run Gradle with the --scan flag. class="language-plaintext">$ ./gradlew build --scan BUILD SUCCESSFUL in 0s 5 actionable tasks: 5 executed Publishing a build scan to scans.gradle.com requires accepting the Gradle Terms of Service defined at https://gradle.com/terms-of-service. Do you accept these terms? [yes, no] yes Gradle Terms of Service accepted. Publishing build scan... https://gradle.com/s/5u4w3gxeurtd2Click the link and explore which tasks where executed, which dependencies where downloaded and many more details!SummaryThat's it! You've now successfully configured and built a Kotlin library project with Gradle. You've learned how to:Initialize a project that produces a Kotlin libraryRun the build and view the test reportCustomize the Jar files the build producesNow you could complete this exercise by trying to compile some Kotlin code that uses the library you just built.

Augmenting Crypto Trading with Bot Development The crypto market fluctuates dramatically. Short-term and long-term investors around the world are interested in them because of their dynamic nature. Since cryptocurrencies can fluctuate within milliseconds, we humans started using crypto trading bots developed using crypto development services to automate the process.What is a Crypto Trading Bot?A bot is a simple automated program that runs on the Internet and performs repetitive tasks more efficiently than humans. In fact, some estimates suggest that more than half of internet traffic consists of bots interacting with websites and users, viewing content, and performing other tasks. Crypto trading bots work on the same basic principle. They are software programs that use artificial intelligence to perform functions based on predefined parameters. No more missed deals or missed opportunities. Whether you want to buy the most undervalued cryptocurrency or add a new cryptocurrency to your portfolio, just use crypto trading and your assets will be automatically traded from anywhere in the world, day or night. You can buy, sell, or hold automatically in a timely, efficient manner. use a bot.Also, Read | Crypto Trading Bot Development | A Quick GuideFor those investing in multiple cryptocurrencies, secure asset storage is just as important as efficient trading. Learn more in our blog on cryptocurrency hot and cold wallets.How Do Crypto Trading Bots Work?To trade with a cryptocurrency bot on a cryptocurrency exchange, you must authorize the trading bot to access your account via an API (application program interface) key. At any time, access may be granted or canceled. So what is the actual mechanics of a profitable cryptocurrency trading bot? Trading is built on Traality by communicating directly with cryptocurrency exchanges and automatically placing orders based on pre-set conditions Bots offer exceptional speed and efficiency, reduced error, and emotionless trading tailored to individual risk tolerance and investment goals.Broadly speaking, trading bots work in four main phases: data analysis > signal generation > risk allocation > execution.Data is king. Therefore, data analysis is essential for the success of cryptocurrency trading bots. Unlike humans, machine learning-powered software can identify, collect, and analyze large amounts of data faster, smarter, and better.Once data analysis is complete, bot signal generation basically does the trader's job of making predictions and identifying possible trades based on market data and technical analysis indicators.In risk allocation, bots allocate risk according to a specific set of parameters and rules set by traders. This typically includes how and to what extent capital is allocated when trading.Execution is the phase in which cryptocurrencies are actually bought or sold based on signals generated by pre-configured trading systems. At this stage, the signal generates buy and sell orders that are sent to the exchange via the API.Also, Check | Can ChatGPT Replace Crypto Trading BotsIf you are planning to integrate payment features into your crypto trading solution, we recommend reading our guide on blockchain-based payment solutions.How to Build a Crypto Trading Bot:Step by StepNow that you have an understanding of cryptocurrency bots and how they work, let's see how to create a crypto trading bot.Programming LanguageList all Crypto ExchangesCreate Accounts on these ExchangesChoose the Type of BotConfirm the AlgorithmEncodingProduct TestingLive DeploymentStep 1: Programming LanguageWe recommend that you choose a language that you are familiar with to build your bot. The most commonly used languages for building cryptobots are:CJavascriptPerlPythonThe advantage of using such a well-known programming language is that it makes it easier to write or modify the code with the help of other programmers if problems arise.Python continues to be one of the most interesting in many areas, such as algorithmic trading. Python is known for its sophisticated libraries and simple basics. As one of the easiest languages for beginners, more and more traders use this language to create their Python trading bots. Using this language, you can create both simple and complex bots with different capabilities.Step 2: Integrate Crypto ExchangesBefore you begin creating, you must also acquire the APIs your bot requires to access the exchanges you want it to trade on. The good news is that all of the major cryptocurrency exchanges, including:BittrexCEX.IOCoinbaseKrakenPoloniexIf you're working on a multi-exchange or multi-currency strategy, it's important to understand multichain crypto wallet development, which enables flexible asset handling across platforms.Step 3: Create Accounts on these ExchangesCreating an account is a very easy process. Please note that the procedure for opening a new account differs depending on the exchange. Note that some services allow anonymous transactions, while others require authorization.Step 4: Choose the Type of BotBefore learning how to create a crypto trading bot, you need to decide what kind of crypto trading bot you want to design. Here are the two most popular types of cryptocurrency trading bots:Arbitrage Bots:Crypto arbitrage is a method of profiting from price movements of a single asset on many trading platforms. It should be noted that more sophisticated trading models take longer to build.Also, Explore | Exploring Crypto Arbitrage Trading Bot and DevelopmentStep 5:AlgorithmA bot's architecture has a huge impact on its performance and performance. Choosing the algorithms your bot uses to analyze your data is important to understanding how your bot works. Algorithmic trading is a huge industry generating billions of dollars in annual revenue. Each method must be supported by a strong mathematical model. Otherwise, you may suffer financial damageStep 6: EncodingNow that you know how to create a crypto trading bot, once you have written the bot's architecture, you can start writing the code.Step 7: Product TestingThe test has two main goals.The main goal is to make sure the bot performs well and can withstand the kinds of data fluctuations thrown at it. Factors such as risk versus return and modeling errors such as "overfitting" should be evaluated at this level. Performance optimization is the second feature. Note that performance means improving the kind of behavior you want your bot to see.Step 8: Live DeploymentAfter all issues have been resolved, we are ready to launch our new automated Bitcoin trading bot.The reputable company continues to provide support after the app's release.

So, without further ado, let's look at the most prominent reasons to develop Stellar based real-world blockchain solutions.Stellar's consensus model intends to serve the real-world problemsThe Stellar Consensus Protocol (SCP) exactly coordinates with real-life business arrangements. Based on the architecture of the internet, the SCP employs a Federated Byzantine Agreement (FBA) model to reach the decentralized consensus. Thus, eliminating any gatekeeper and central authority. Anyone with an internet connection can join the Stellar universe. In this universe, similar to the real world, participants get the ability to choose who they want to trust to share the information. For validating a transaction, participants in it do not require the complete network to agree. It's only the other members that it cares about. Each participant, and the ones it trusts forms up what's exclaimed as ‘Quorum Slice.' Participants can join multiple slices. And, if the slices are overlapping, it refers to as ‘Quorum Intersections.' These intersections are the reason it has become possible to create a stable and secure system-wide consensus.Transfer money as if you're sending an emailInstead of utilizing a long, hard-to-remember alphanumeric string as your address, Stellar allows using an email address or other short aliases depending on your use case. Imagine the time when mail providers will come integrated with Stellar. Then, they'll be able to automatically connect a wallet address to each user's email ID. Envision the straightforwardness and inexpensiveness of sending money across the world to anyone using their email address!SecurityFor large, as well as small, enterprise businesses, it is a must to secure transactions through necessary precautions. Stellar prevents bad actors from reaching the attack-surface by not using a Turing-complete system. Stellar offers improved functionality. It saves from threats due to its design and provides an efficient payment system and means of exchange.LiquidityStellar is an excellent blockchain project that addresses major challenges to fundraising, such as access to liquidity and capital. Stellar's system comes equipped with a built-in decentralized exchange. It means you can enable thetrading of tokens moment they are created. It's expected that Stellar's decentralized exchange would provide an all-inclusive equitable ecosystem.Documentation & SupportStellar's boasts an amazing documentation and community support. The docs are precise, informative, and easy to understand. Stellar's Slack channels are home to some of the Stellar developers and other members of the community. They are often found holding lively discussions and are always ready to lend a helping hand. Consequently, it makes troubleshooting a breeze. And, significantly, demonstrates why some of the reputed and largest banks and financial institutions globally are moving toward adopting Stellar based real-world blockchain solutions.The Right FocusStellar is a combination of cost-effectiveness, high speed and focus continual developments. However, it takes some transactional charge to prevent denial of service attacks. During the tests with Barclays, Deloitte, and IBM, it has been proven that Stellar can safely accomplish up to 1,000 TPS, while the confirmation averages 3–5 seconds. Stellar proves that it can do everything that a modern blockchain does, by providing a robust, secure, and functional distributed ledger.Final WordsStellar aims to propel global financial access with cutting-edge innovation. While other blockchain platforms may be far from addressing today's problems, Stellar based real-world blockchain solutions shine.

Anatomy of Android Application There are four building blocks to an Android application:ActivityIntent ReceiverServiceContent ProviderNot every application needs to have all four, but your application will be written with some combination of these.Once you have decided what components you need for your application, you should list them in a file called AndroidManifest.xml. This is an XML file where you declare the components of your application and what their capabilities and requirements are. We will discuss soon, what the AndroidManifest.xml is responsible for.Activity :Activities are the most common of the four Android building blocks. An activity is usually a single screen in your application. Each activity is implemented as a single class that extends the Activity base class. Your class will display a user interface composed of Views and respond to events. Most applications consist of multiple screens. For example, a text messaging application might have one screen that shows a list of contacts to send messages to, a second screen to write the message to the chosen contact, and other screens to review old messages or change settings. Each of these screens would be implemented as an activity.When a new screen opens, the previous screen is paused and put onto a history stack. The user can navigate backward through previously opened screens in the history. Screens can also choose to be removed from the history stack when it would be inappropriate for them to remain. Android retains history stacks for each application launched from the home screen.Intent and Intent Filters :Android uses a special class called Intent to move from screen to screen. Intent describe what an application wants done. The two most important parts of the intent data structure are the action and the data to act upon. Typical values for action are MAIN (the front door of the application), VIEW, PICK, EDIT, etc. The data is expressed as a Uniform Resource Indicator (URI). For example, to view a website in the browser, you would create an Intent with the VIEW action and the data set to a Website-URI.new Intent(android.content.Intent.VIEW_ACTION, ContentURI.create("http://anddev.org")); There is a related class called an IntentFilter. While an intent is effectively a request to do something, an intent filter is a description of what intents an activity (or intent receiver, see below) is capable of handling.Activities publish their IntentFilters in the AndroidManifest.xml file.Intent Receiver :You can use an IntentReceiver when you want code in your application to execute in reaction to an external event, for example, when the phone rings, or when the data network is available, or when it's midnight. Intent receivers do not display a UI, although they may display Notifications to alert the user if something interesting has happened. Intent receivers are also registered in AndroidManifest.xml, but you can also register them from code using Context.registerReceiver().Service :A Service is code that is long-lived and runs without a UI. A good example of this is a media player playing songs from a play list. In a media player application, there would probably be one or more activities that allow the user to choose songs and start playing them. However, the music playback itself should not be handled by an activity because the user will expect the music to keep playing even after navigating to a new screen. In this case, the media player activity could start a service using Context.startService() to run in the background to keep the music going. The system will then keep the music playback service running until it has finished. (You can learn more about the priority given to services in the system by reading Life Cycle of an Android Application.) Note that you can connect to a service (and start it if it's not already running) with the Context.bindService() method. When connected to a service, you can communicate with it through an interface exposed by the service. For the music service, this might allow you to pause, rewind, etc.Content Provider :Applications can store their data in files, a SQLite database, preferences or any other mechanism that makes sense. A content provider, however, is useful if you want your application's data to be shared with other applications. A content provider is a class that implements a standard set of methods to let other applications store and retrieve the type of data that is handled by that content provider.
