使用AOSP构建APK

Question

Using AOSP we can build own Android with some features.

I have setup environment using google documentation and another web sites, and in tutorials says -

make adb fastboot. Update yours android OS with yours customization.

But i just need use @SystemApi classes for build one app, what i should to do?

I searched in web for one month, but still didn't find.

Methods marked as @hide or @SystemAPI are not part of the official SDK, and are not intended to be used generally.

Yet, until lately you could access all of them either by Reflection , or by using a custom android.jar that has those methods too. See this project for the list of android.jar: https://github.com/anggrayudi/android-hidden-api

If your Android version is below P, that's all you need to do. Otherwise keep reading:

In Android P, Google removed access to non-SDK interfaces , so you cannot use those methods as above. In this case you'd have to remove the @SystemApi and @hide annotations from the classes and methods you need, compile and flash the update to the device. Then you can use the above methods
