I'm getting a null pointer exception in TabHost.java whenever I start my TabActivity by pressing the enter key or pressing the trackball on the button that starts the activity.
So I've got a button called "start" that in its onClick handler will start a TabActivity. Tapping on the button starts the TabActivity fine, however when I press the button using the "enter" key or the trackball I get the following trap. I've seen another thread related to this at http://groups.google.com/group/android-developers/browse_thread/thread/d6633cda4d944d24/623583dc966c65f3?show_docid=623583dc966c65f3 My stack trace is below: 10-28 22:10:18.849: ERROR/AndroidRuntime(1078): Uncaught handler: thread main exiting due to uncaught exception 10-28 22:10:18.849: ERROR/AndroidRuntime(1078): java.lang.NullPointerException 10-28 22:10:18.849: ERROR/AndroidRuntime(1078): at android.widget.TabHost.onTouchModeChanged(TabHost.java:179) 10-28 22:10:18.849: ERROR/AndroidRuntime(1078): at android.view.ViewTreeObserver.dispatchOnTouchModeChanged (ViewTreeObserver.java:591) 10-28 22:10:18.849: ERROR/AndroidRuntime(1078): at android.view.ViewRoot.ensureTouchModeLocally(ViewRoot.java:1877) 10-28 22:10:18.849: ERROR/AndroidRuntime(1078): at android.view.ViewRoot.performTraversals(ViewRoot.java:715) 10-28 22:10:18.849: ERROR/AndroidRuntime(1078): at android.view.ViewRoot.handleMessage(ViewRoot.java:1613) 10-28 22:10:18.849: ERROR/AndroidRuntime(1078): at android.os.Handler.dispatchMessage(Handler.java:99) 10-28 22:10:18.849: ERROR/AndroidRuntime(1078): at android.os.Looper.loop(Looper.java:123) 10-28 22:10:18.849: ERROR/AndroidRuntime(1078): at android.app.ActivityThread.main(ActivityThread.java:4203) 10-28 22:10:18.849: ERROR/AndroidRuntime(1078): at java.lang.reflect.Method.invokeNative(Native Method) 10-28 22:10:18.849: ERROR/AndroidRuntime(1078): at java.lang.reflect.Method.invoke(Method.java:521) 10-28 22:10:18.849: ERROR/AndroidRuntime(1078): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run (ZygoteInit.java:791) 10-28 22:10:18.849: ERROR/AndroidRuntime(1078): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:549) 10-28 22:10:18.849: ERROR/AndroidRuntime(1078): at dalvik.system.NativeStart.main(Native Method) But with no word from the Android team. Is this a framework issue? Thanks Lee --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
