The Android framework provides several solutions to mitigate the need for these implicit broadcasts. For example, the JobScheduler API provides a robust mechanism to schedule network operations when specified conditions, such as connection to an unmetered network, are met.

Therefore, all developers should check to make sure that their apps do not crash on devices running Android 7. Apps should not use native libraries that are not included in the NDK because they may change or be removed between different versions of Android.
Also, because there are no compatibility requirements for platform libraries not included in the NDK, different devices may offer different levels of compatibility.
If your app loads one of these libraries, logcat generates a warning and a toast appears on the target device to notify you.
If you see these warnings, you should update your app to either include its own copy of those libraries or only use the public NDK APIs. Future releases of the Android platform may restrict the use of private libraries altogether and cause your app to crash.
