Android Close Application Programmatically Tutorial

While designing an app you may have a login screen and after the user logs in the app and is on the Main member activity, you may also want the app to exit after the user presses the back button and isn't directed towards the Login screen again.

Android Close Application Programmatically


To prevent your Android app user to be redirected towards the login screen again here is a simple Java code that you can use in Android Studio in the Member Activity Java file to close application programmatically:

@Overridepublic void onBackPressed() {
    Intent start = new Intent(Intent.ACTION_MAIN);
    start.addCategory(Intent.CATEGORY_HOME);
    start.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    start.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    startActivity(start);
}

The code shown above kills the activity and user is directed to Home Screen of his Android.
