    text
    copied!<p>Hi I have searched everywhere here and on Google, without getting a correct answer. So I post a new question:</p> <p>I have several Android Apps that were working perfectly with 1.6 up to 2.3...</p> <p>BUT now, with Android 4.0 (ICS), I have users reporting that the screen is flashing on the homepage when the application is launched and nothing can be done but "home" and Force Stop the App... (then. you can start the app again, and it eventually works... :O)</p> <p>I have tested the App on the emulator and on several devices including the Galaxy S 3 with Android 4.0.4 and I could never reproduce the issue !! :(( It seems that the issue is mostly on the HTC One...</p> <p>Here is the simple code of the activity</p> <pre><code>public class WelcomePage extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
