4. White/Blank screen on Android Simulator

White/Blank screen on Android Simulator


  • Dear All,

    if i run the test HelloWorld application with QT Creator on Android Simulator the system shows a white blank screen.
    How is possible to fix this?

    I'm using a Mac.

    is that the whole output?

    If so you need to post your logcat pls. But clear it before you start the app to keep it at small as possible.

    adb logcat -c
>>> START YOUR APP AND LET IT CRASH
adb logcat -d > logcat.txt

    Please note also that if takes the .APK debug file and installs on my Android Device, seems work fine, but not exactly.
    If i switch to home and then switches to application , the application crashed!
    Could be a problem linked to this post?

    This is a simple application

    as i said, adb is part of the Android SDK. Call it directly from there.

    these are the lines i would be suspicious about.

    Seems this is only a Emulator related issue.

    so is not possible to fix? Is very strange.

    I tried to tun the emulator beforw with hte following command lines but nothing change:

    emulator -avd Galaxy_Nexus_API_22 -gpu host
    emulator -avd Galaxy_Nexus_API_22 -gpu on
    emulator -avd Galaxy_Nexus_API_22 -gpu off
