Quitting application in Android

Question

I want to quit application in Android. Just put a \"quit\" button, which kills my app.

I know I shouldn\'t do this. I know that this is not the philosophy of the OS.

Answer 1

Close all the previous activities as follows:

    Intent intent = new Intent(this, MainActivity.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    intent.putExtra("Exit me", true);
    startActivity(intent);
    finish();

Then in MainActivity onCreate() method add this to finish the MainActivity

    setContentView(R.layout.main_layout);

    if( getIntent().getBooleanExtra("Exit me", false)){
        finish();
        return; // add this to prevent from doing unnecessary stuffs
    }
