Answer 1

You have to change extends AppCompatActivity to ActivityGroup After that change

tabhostku.setup();

to

tabhostku.setup(this.getLocalActivityManager());

Answer 2

Try this,

Change,

tabhostku.setup();

to

mlam = new LocalActivityManager(this, false);
tabhostku.setup(mlam );

And in onPause and onResume add the following code.

@Override
public void onPause() {
    super.onPause();
    try {
        mlam.dispatchPause(isFinishing());
    } catch (Exception e) {}
}

@Override
public void onResume() {
    super.onResume();
    try {
        mlam.dispatchResume();
    } catch (Exception e) {}
}
