Build custom SDK with AOSP changes

Question

I am trying to build my app (uses many hidden api and properties) in android studio. I have modified the AOSP code to expose these hidden apis. In order to make the build successful I have added the classes.jar as the external lib to my project. But that doesn't resolve the issue. It was still showing errors :

error: cannot find symbol method getService()   
error: cannot find symbol variable userSetLocale    
error: cannot find symbol method getInstance()  
error: cannot find symbol variable INJECT_INPUT_EVENT_MODE_WAIT_FOR_FINISH  
error: cannot find symbol variable INJECT_INPUT_EVENT_MODE_ASYNC    

Now I am trying to make the custom SDK with this modified AOSP code.

Note : Already tried and failed with the following solutions

• Exposing hidden APIs android L (SDK 21) in Android Studio

• How do I build the Android SDK with hidden and internal APIs available?

• https://github.com/anggrayudi/android-hidden-api

Can anyone help to build custom SDK based on the modified AOSP code

Answer 1

I solved the issue by changing the orderEntry of sdk in app.iml and giving the absolute path of framework.jar in modules build.gradle

Answer 2

Add the following in you root project's build.gradle. ${rootDir}/libs/framework.jar is the jar build from you aosp code.

subprojects {
gradle.projectsEvaluated {
    tasks.withType(JavaCompile) {
        options.compilerArgs.add("-Xbootclasspath/p:${rootDir}/libs/framework.jar")
    }
 }
}

There are red errors in the editor. But it can be build successful. Demo project:https://github.com/auxor/AppWithModifiedFramework/
