My android application won't start up. When i click the icon on the device it pop up with a force close error. I have created the application out of an old un-used application in my control panel. I have done this to 2 applications, and they both have the same error showing?!? https://dl.dropbox.com/u/70063294/Screen%20Shot%202012-07-01%20at%209.32.17%20PM.png

If you have the app on your device you know the following: App compiled OK. So, the problem will be with: Home screen Bad screen nickname - first character must be a letter ? Bad image file name - check for spaces Just some thoughts. Run the logcat, it may tell us something interesting. Fred

Its not the nickname or the images, am running the log cat now. this is what my logcat says: 07-02 10:01:52.548: W/ZZ(310): catchphrasequiz_appDelegate:loadAudioPlayer 07-02 10:01:52.588: W/ZZ(310): BT_application: Creating root-app object. 07-02 10:01:52.588: W/ZZ(310): BT_device: Creating root-device object. 07-02 10:01:52.598: W/ZZ(310): BT_device: This device uses an Android display density of: 240dpi (dots per inch) 07-02 10:01:52.598: W/ZZ(310): BT_device: This device can take pictures. 07-02 10:01:52.608: W/ZZ(310): BT_device: This device can take videos. 07-02 10:01:52.608: W/ZZ(310): BT_device: This device can send emails. 07-02 10:01:52.618: W/ZZ(310): BT_device: This device is GPS capable. 07-02 10:01:52.618: W/ZZ(310): BT_user: Creating root-user object. 07-02 10:01:52.679: W/ZZ(310): BT_activity_root:onCreate 07-02 10:01:52.798: D/dalvikvm(310): GC_EXTERNAL_ALLOC freed 1397 objects / 95736 bytes in 76ms 07-02 10:01:52.858: W/ZZ(310): BT_device:updateDeviceConnectionType: ConnectionType: CELL 07-02 10:01:52.858: W/ZZ(310): BT_device:updateDeviceSize This device has a screen size of: 480 (width) x 800 (height). 07-02 10:01:52.858: W/ZZ(310): BT_device:updateDeviceSize This application considers this to be a "small device" 07-02 10:01:52.858: W/ZZ(310): BT_device:updateDeviceSize This device is in "portrait" orientation. 07-02 10:01:52.928: W/ZZ(310): BT_activity_root:loadAppData loading BT_config.txt from /assests folder in Eclipse project... 07-02 10:01:53.228: W/ZZ(310): BT_fileManager: readTextFileFromAssets: "/BT_config.txt" 07-02 10:01:53.228: I/global(310): Default buffer size used in BufferedReader constructor.

It's looking for, but can't find, the home screen which is a splashscreen with item id B6D6ACA21F5E3B36DE54D51 in the config file. Try removing the splashscreen if you haven't already and use another home screen, see if that helps. Might try refreshing/updating the config file too.

Good call, @raveyd! Splash screens seem to be super problematic with Android...I'd avoid them if at all possible. Mark

I have already removed the splash screen and changed the home screen. still no luck. i will try the config file. Maybe i have to put a splash scene back on, because the previous app had a splash screen?

Aha! all i needed to do was add a splash screen, now its working :)

Just jinxed myself, not working now..... nope, just trying to run the wrong app... ( i have 2 apps with the same name, on was for testing....

If you remove the SplashScreen itself, make sure you also remove the SplashScreen setting from your Global Theme. You need to remove ALL traces of the screen and places it was connected to. Then, copy your current Configuration Data file to your local (or wherever you store it) BT_Config.txt file and rebuild your app. Don't forget to do a Project...Clean before you do your build again.

Ok thanks.
