If you have to implement a functionality where-in you want no action to occur when the Back Button is being pressed on your Android App, you need to Override the method onBackPressed()
@Override
public void onBackPressed() {
//Do noting
}Note that the above code will work when you have set API level 2.0 (5) or higher. If you have set your minSdk below API level 5 use the below code.
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
return true;
}
return super.onKeyDown(keyCode, event);
