Menu
in an app that I am writing, there is a part of it that allows you to change a curtain setting. the problem is, that this setting won't take effect until the activity is recreated. is there a way to tell the app to restart using the onResume() method (hopefully allowing it to save everything in the onSaveInstanceState())?

If you just want to reload the activity, for whatever reason, you can use this. recreate(); where this is the Activity. This is never a good practice. Instead you should startActivity() for the same activity and call finish() in the current one.
You can determine if the activity is finishing by user choice (user chooses to exit by pressing back for example) using isFinishing() in onDestroy . @Override protected void onDestroy() { super. onDestroy(); if (isFinishing()) { // wrap stuff up } else { //It's an orientation change. } }
Navigate to the app > res > layout > activity_main.
This has been posted before:
Intent intent = getIntent();
finish();
startActivity(intent);
As of API level 11, you can also just call an activity's recreate() method. Not only is this cleaner because it is less code, it avoids issues that may arise if your activity was launched by an implicit intent.
