I just found a strange issue in my application which contains a ListView. When one item is clicked, a TabActivity will be launched, i got a NullPointerException when i press the item by using trackball. But it's fine when i press the item by using finger.
This is the logcat message: D/AndroidRuntime(32224): Shutting down VM W/dalvikvm(32224): threadid=3: thread exiting with uncaught exception (group=0x4000fe70) E/AndroidRuntime(32224): Uncaught handler: thread main exiting due to uncaught exception E/AndroidRuntime(32224): java.lang.NullPointerException E/AndroidRuntime(32224): at android.widget.TabHost.onTouchModeChanged (TabHost.java:178) E/AndroidRuntime(32224): at android.view.ViewTreeObserver.dispatchOnTouchModeChanged (ViewTreeObserver.java:591) E/AndroidRuntime(32224): at android.view.ViewRoot.ensureTouchModeLocally(ViewRoot.java:1736) E/AndroidRuntime(32224): at android.view.ViewRoot.performTraversals (ViewRoot.java:667) E/AndroidRuntime(32224): at android.view.ViewRoot.handleMessage (ViewRoot.java:1482) E/AndroidRuntime(32224): at android.os.Handler.dispatchMessage (Handler.java:99) E/AndroidRuntime(32224): at android.os.Looper.loop(Looper.java:123) E/AndroidRuntime(32224): at android.app.ActivityThread.main (ActivityThread.java:3948) E/AndroidRuntime(32224): at java.lang.reflect.Method.invokeNative (Native Method) E/AndroidRuntime(32224): at java.lang.reflect.Method.invoke (Method.java:521) E/AndroidRuntime(32224): at com.android.internal.os.ZygoteInit $MethodAndArgsCaller.run(ZygoteInit.java:782) E/AndroidRuntime(32224): at com.android.internal.os.ZygoteInit.main (ZygoteInit.java:540) E/AndroidRuntime(32224): at dalvik.system.NativeStart.main(Native Method) Has anyone met this kind of issue?
