It is important to note, you cannot mix AppCompat and Jetpack in the same project. You must convert everything to use Jetpack if you want to upgrade. The support library artifacts are being deprecated and all future development is going into AndroidX , so there's no avoiding this migration. Alan Viverette sums this up nicely: “There won’t be a 29.0.0, so Android Q APIs will only be in AndroidX” The stable release of 28.0.0 will be the final feature release packaged as android.support . All subsequent feature releases will only be made available as androidx-packaged artifacts. Below tips will give you a clearer transition path. The current version of AppCompat (v28.x) is exactly the same as AndroidX (v1.x). In fact, the AppCompat libraries are machine generated by changing maven coordinates and package names of the AndroidX codebase. For example, android.support.v7.app.AppCompatActivity is now androidx.appcompat.app.AppCompatActivity For a complete listi

I am here to give some inputs on android PI migration. .  Apps must target at least API level 28 to ensure it is built on the latest APIs optimized for security and performance . From August 2019, new apps must target at least Android 9.0 (API level 28) . The objective here is to make sure that your existing app works as-is on Android 9. Because some platform changes might affect the way your app behaves, some adjustments might be necessary, but you do not need to use new APIs or change your targetSdkVersion. Android Service Problem On Oreo, startService() will throw IllegalStateException. This can be fixed by changing it to startForegroundService(). but it also stops the service immediately if you don’t bind to the Notification with Service.startForeground() within 5 seconds. For other background service we decided to use the WorkManager . Implementation: Since we have minSdkVersion 19, We migrated to workmanger for scheduled tasks and we still use JobIntentSer

64-bit CPUs bring in areas such as artificial intelligence, machine learning, and immersive mobile. Supporting 64-bit prepares the ecosystem for the innovation enabled by the advanced compute capabilities of 64-bit devices, and for future Android devices that only support 64-bit code. Starting August 1, 2019 , all new apps and app updates that include native code must have 64-bit versions as well as 32-bit versions when publishing to Google Play. How am I affected? Your app makes use of native code if it meets any of the following criteria: - Your app makes use of C or C++ code. - Your app links with third-party libraries that contain native code. - Your app is built by a third-party app builder that uses native libraries. Preparing for the 64-bit requirement 1. Inspect your APK or app bundle for native code. You can check for .so files using APK Analyzer. Identify whether they are built from your own code or are imported by an SDK or library that you are using. If y
