Launch Existing Singletask Activity From Launcher Icon

Scenario: Activity A (MAIN and LAUNCHER in manifest) starts up when clicking on launcher icon. In turn it launches Activity B. Activity B then launches our main app Activity C (MA

Solution 1:

See similar scenario here.

In your case, I would recommend using a similar approach, where you would have a SharedPreference that would persist a value representing whether your app had previously been launched.

Create a simple Activity that will contain the logic for what you are trying to do here. In that activity's ("pre-A" Activity) onResume() method, check the value of the preference representing whether the app has ran previously.

If it has not previously been ran, launch an intent to Activity A, which calls the subsequent B and C activities; otherwise, launch an intent to Activity C.

Seems pretty straightforward, just remember to define the new "Pre-A" activity in your manifest!
