When starting your call, it looks fine.

There is a difference between android 11+ and down in bringing your app to the front though.

Android 10 or less you need to start a new intent, android 11+ you simply use BringTaskToFront

In the call state IDLE:

if (Build.VERSION.SDK_INT >= 11) {
    ActivityManager am = (ActivityManager) activity.getSystemService(Activity.ACTIVITY_SERVICE);
    am.moveTaskToFront(MyActivity.MyActivityTaskId, ActivityManager.MOVE_TASK_WITH_HOME);
} else {
    Intent intent = new Intent(activity, MyActivity.class);
    activity.startActivity(intent);
}

I set the MyActivity.MyActivityTaskId when making the call on my activity like so, it this doesnt work, set this variable on the parent activity page of the page you want to get back to.

MyActivity.MyActivityTaskId = this.getTaskId();

MyActivityTaskId is a static variable on my activity class

public static int MyActivityTaskId = 0;

I hope this will work for you. I use the above code a bit differently, I open my app as soon as the call is answered sothat the user can see the details of the caller.

I have set some stuff in the AndroidManifest.xml as well:

/*Dont really know if this makes a difference*/

and permissions:

Please ask questions if or when you get stuck.
