问题
I have the following Android exception. It is reported by Bugsense and I cannot find out where it comes from as there is no reference to any class of my app.
java.lang.IndexOutOfBoundsException: Invalid index 0, size is 0 at java.util.ArrayList.throwIndexOutOfBoundsException(ArrayList.java:251) at java.util.ArrayList.get(ArrayList.java:304) at android.widget.HeaderViewListAdapter.isEnabled(HeaderViewListAdapter.java:164) at android.widget.AbsListView$ListItemAccessibilityDelegate.onInitializeAccessibilityNodeInfo(AbsListView.java:2512) at android.view.View.onInitializeAccessibilityNodeInfo(View.java:4849) at android.widget.LinearLayout.onInitializeAccessibilityNodeInfo(LinearLayout.java:1768) at android.view.View.createAccessibilityNodeInfo(View.java:4812) at android.view.AccessibilityInteractionController$AccessibilityNodePrefetcher.prefetchDescendantsOfRealNode(AccessibilityInteractionController.java:825) at android.view.AccessibilityInteractionController$AccessibilityNodePrefetcher.prefetchDescendantsOfRealNode(AccessibilityInteractionController.java:848) at android.view.AccessibilityInteractionController$AccessibilityNodePrefetcher.prefetchDescendantsOfRealNode(AccessibilityInteractionController.java:848) at android.view.AccessibilityInteractionController$AccessibilityNodePrefetcher.prefetchDescendantsOfRealNode(AccessibilityInteractionController.java:848) at android.view.AccessibilityInteractionController$AccessibilityNodePrefetcher.prefetchDescendantsOfRealNode(AccessibilityInteractionController.java:848) at android.view.AccessibilityInteractionController$AccessibilityNodePrefetcher.prefetchAccessibilityNodeInfos(AccessibilityInteractionController.java:734) at android.view.AccessibilityInteractionController.findAccessibilityNodeInfoByAccessibilityIdUiThread(AccessibilityInteractionController.java:205) at android.view.AccessibilityInteractionController.access$400(AccessibilityInteractionController.java:49) at android.view.AccessibilityInteractionController$PrivateHandler.handleMessage(AccessibilityInteractionController.java:985) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:137) at android.app.ActivityThread.main(ActivityThread.java:4867) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:511) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1007) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:774) at dalvik.system.NativeStart.main(Native Method)
I do suspect it has something to do with updating a widget. Any ideas on how to trace?
回答1:
Got similar Nullpointer with a Google map view. try and turn off any accessibility options enabled on your phone? And there is a another accessibility bug reported on the Android Issues tracker here
It looks like there is no easy way to turn of accessibility from code, except for overriding the addChildrenForAccessibility method in a custom view. (see above link)
