The only problem i see using android:launchMode="singleTask" is whenever you minimize app and start app by pressing app icon again then app start from scratch and doesn't acquire its state. so i have opted to use

which will keep only one instance and clear all activities on top of that.

intent.setFlags( Intent.FLAG_ACTIVITY_CLEAR_TOP );
current_activity.startActivity( intent );
