Back Button Works Like Home

Is it possible to change this code: @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_BACK) { } return super.onKeyDown(

Solution 1:

try this,

@OverridepublicvoidonBackPressed() {
        IntentbacktoHome=newIntent(Intent.ACTION_MAIN);
        backtoHome.addCategory(Intent.CATEGORY_HOME);
        backtoHome.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(backtoHome);
    }

Adding this to your Activity, will make it look like your app is responding to a Home Button Click event

Solution 2:

Going to home screen programmatically

to launch home screen

IntentstartMain=newIntent(Intent.ACTION_MAIN);
startMain.addCategory(Intent.CATEGORY_HOME);
startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(startMain);

Note :

This Intent will start the launcher application that the user has defined. Be careful with this because this will look like your application crashed if the user does not expect this.

Solution 4:

@Override

    NavUtils.navigateUpFromSameTask(this);
}

If something doesn't work like expected try it with uncommented

    super.onBackPressed();
