I have transparent activity after I kill it (onStop/onDestroy) i want to create Dialog but I getting error : 

java.lang.RuntimeException: Unable to destroy activity {package name/myclass}: java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState

hole code looks like : 

public class TransparentTip extends FragmentActivity {

    Button ok;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.transparent_tip);
        ok=(Button)findViewById(R.id.bToK);
    }

    public void buttonClick(View view) {
        if (view.getId() == R.id.bToK)
        {
            finish();
            overridePendingTransition(R.anim.abc_fade_in, R.anim.abc_fade_out);
        }
    }

    @Override
    public void onBackPressed() {
        super.onBackPressed();
        overridePendingTransition(R.anim.abc_fade_in, R.anim.abc_fade_out);
    }

    @Override
    protected void onDestroy()
    {
        super.onDestroy();
        DialogChoiceActivity dialog = new DialogChoiceActivity();
        dialog.show(getSupportFragmentManager(),"my_dialog");

    }
}

P.S Creating dialog works so there is no need to put here DialogChoideActivity code.

You must allow state loss for dialog because you are using show during destruction. Use this

public static void showDialogAllowingStateLoss(FragmentManager fragmentManager, DialogFragment dialogFragment, String tag) {
    FragmentTransaction ft = fragmentManager.beginTransaction();
    ft.add(dialogFragment, tag);
    ft.commitAllowingStateLoss();
}

instead of dialog.show(getSupportFragmentManager(),"my_dialog");

Check also Demystifying Android’s commitAllowingStateLoss() for caveats using commitAllowingStateLoss.

  • I add your function and change my dialog.show on showDialogAllowingStateLoss(getSupportFragmentManager(),dialog,"my_dialog"); and now I'm getting error like : 'Unable to destroy activity : java.lang.IllegalStateException: Activity has been destroyed' –  May 10 '17 at 08:20
  • You can fix the problem starting TransparentTip through startActivityForResult(). Then you use show() in the onActivityResult callback of the calling Activity. – Marco Righini May 10 '17 at 09:54
