What is way to show authorization activity instead of main app activity?

Question

I have need to show autorizationa activity if user not autorized.

I have use Launcher activity (has nohistory flag) with next code:

protected void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);

    if (Autorization.isAutorized()) 
    {
        Intent newIntent = new Intent(this, MainActivity.class);
        // add some flags????
        startActivity(newIntent);
    }
    else startActivity(new Intent(this, AutorizationActivity.class));
}

When autorization are complete, AutorizationActivity starts Launcher with FLAG_ACTIVITY_CLEAR_TOP and then Launcher starts MainActivity, but I have some trubles with backstack. By pressing back in MainActivity android shows AutorizationActivity again instead to hide task.

What flags I must use to prevent go back to AutorizationActivity from MainActivity?

I have remove no history flag and add finish(); after start MainActivity methods. It is correct way? — Nik, Apr 17 '12 at 06:13
It is work! Also I have add in AutorizationActivity next code: public void onBackPressed() { moveTaskToBack(true); } — Nik, Apr 17 '12 at 06:25

There are several ways to do this , the easiest would be to use the AndroidManifest.xml file. Just add android:noHistory = "true" in the authorization activty.

Also have a look at the following question : removing an activity from the history stack

try setting flags for AuthorizationActivity in Manifest something like this.... right now your flag applies only to MainActivity and not the Current Activity.. so set in Manifest instead..
