Clear your current Activity stack and launch a new Activitysuggest change
If you want to clear your current Activity stack and launch a new Activity (for example, logging out of the app and launching a log in Activity), there appears to be two approaches.
1. Target (API >= 16)
finishAffinity() from an Activity
2. Target (11 <= API < 16)
Intent intent = new Intent(this, LoginActivity.class); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK |Intent.FLAG_ACTIVITY_CLEAR_TOP); startActivity(intent); finish();
