How to use the sdk which is built by modifying the aosp framework code?

Question

I am new in Android Open Source Project (ASOP). I have been trying to make a custom android version with my own changes for research purposes. I have changed some code in the framework in Acitivty.java class. Added a custom function of mine like below:

 public final void requestPermissions(@NonNull String[] permissions, int requestCode, String permReason, String dataScope) {
    
    Log.i("PermissionTracker", "Rashed Tracking Permission Manager having requestCode"+Integer.toString(requestCode));
Log.i("PermissionReason", "I am asking permission because of "+permReason);
Log.i("PermissionReason", "The data scope would be "+dataScope);

/*
        Rashed edit end April 23, 2021
    */
    if (requestCode < 0) {
        throw new IllegalArgumentException("requestCode should be >= 0");
    }
    if (mHasCurrentPermissionsRequest) {
        Log.w(TAG, "Can request only one set of permissions at a time");
        // Dispatch the callback with empty arrays which means a cancellation.
        onRequestPermissionsResult(requestCode, new String[0], new int[0]);
        return;
    }
    Intent intent = getPackageManager().buildRequestPermissionsIntent(permissions);
    startActivityForResult(REQUEST_PERMISSIONS_WHO_PREFIX, intent, requestCode, null);
    mHasCurrentPermissionsRequest = true;
}

After that, I have done some other changes as well where I mostly added some log messages and got the output. I built the directory using the following commands and it worked:

. build/envsetup.sh
lunch sdk_phone_x86 sdk-eng
make -j16 sdk

My target was to generate the custom sdk as well which can be used in Android studio as well where I am working in another app. I would like to call my modified function from the app in the Android Studio. I have successfully updated the Android Studio sdk directory. But the problem is that, I cannot see my modified code in the Android Studio. Can anyone help me with that? Thanks for your kind suggestion in advance.

If your modification is part of android frameworks, you need to copy modified jar from out/target/common/obj/JAVA_LIBRARIES/framework_intermediates(for ex)/classes.jar in your Android Studio project.

You need also to modify top-level gradle build to add :

allprojects {
    repositories {
        jcenter()
    }
    gradle.projectsEvaluated {
        tasks.withType(JavaCompile) {
            options.compilerArgs << '-Xbootclasspath/p:app/src/main/lib/framework.jar'
        }
    }
