I am trying to integrate a third party location finding service into my app and I am using the results of the location to place an overlay onto my map. The answer to this question is not "use MyLocationOverlay". I am moving away from that for non-GPS accuracy reasons.
When the third party location callback is executed, I update where this overlay is to reflect the new location. Doing this makes the application throw a ConcurrentModificationException. Here is the full stack trace: ERROR/AndroidRuntime(5440): Uncaught handler: thread main exiting due to uncaught exception ERROR/AndroidRuntime(5440): java.util.ConcurrentModificationException ERROR/AndroidRuntime(5440): at java.util.AbstractList $SimpleListIterator.next(AbstractList.java:66) ERROR/AndroidRuntime(5440): at com.google.android.maps.OverlayBundle.draw(OverlayBundle.java:44) ERROR/AndroidRuntime(5440): at com.google.android.maps.MapView.onDraw(MapView.java:471) ERROR/AndroidRuntime(5440): at android.view.View.draw(View.java: 5838) ERROR/AndroidRuntime(5440): at android.view.ViewGroup.drawChild (ViewGroup.java:1486) ERROR/AndroidRuntime(5440): at android.view.ViewGroup.dispatchDraw (ViewGroup.java:1228) ERROR/AndroidRuntime(5440): at android.view.ViewGroup.drawChild (ViewGroup.java:1484) ERROR/AndroidRuntime(5440): at android.view.ViewGroup.dispatchDraw (ViewGroup.java:1228) ERROR/AndroidRuntime(5440): at android.view.View.draw(View.java: 5841) ERROR/AndroidRuntime(5440): at android.widget.FrameLayout.draw (FrameLayout.java:352) ERROR/AndroidRuntime(5440): at android.view.ViewGroup.drawChild (ViewGroup.java:1486) ERROR/AndroidRuntime(5440): at android.view.ViewGroup.dispatchDraw (ViewGroup.java:1228) ERROR/AndroidRuntime(5440): at android.view.ViewGroup.drawChild (ViewGroup.java:1484) ERROR/AndroidRuntime(5440): at android.view.ViewGroup.dispatchDraw (ViewGroup.java:1228) ERROR/AndroidRuntime(5440): at android.view.View.draw(View.java: 5841) ERROR/AndroidRuntime(5440): at android.widget.FrameLayout.draw (FrameLayout.java:352) ERROR/AndroidRuntime(5440): at com.android.internal.policy.impl.PhoneWindow$DecorView.draw (PhoneWindow.java:1847) ERROR/AndroidRuntime(5440): at android.view.ViewRoot.draw (ViewRoot.java:1217) ERROR/AndroidRuntime(5440): at android.view.ViewRoot.performTraversals(ViewRoot.java:1030) ERROR/AndroidRuntime(5440): at android.view.ViewRoot.handleMessage (ViewRoot.java:1482) ERROR/AndroidRuntime(5440): at android.os.Handler.dispatchMessage (Handler.java:99) ERROR/AndroidRuntime(5440): at android.os.Looper.loop(Looper.java: 123) ERROR/AndroidRuntime(5440): at android.app.ActivityThread.main (ActivityThread.java:3948) ERROR/AndroidRuntime(5440): at java.lang.reflect.Method.invokeNative(Native Method) ERROR/AndroidRuntime(5440): at java.lang.reflect.Method.invoke (Method.java:521) ERROR/AndroidRuntime(5440): at com.android.internal.os.ZygoteInit $MethodAndArgsCaller.run(ZygoteInit.java:782) ERROR/AndroidRuntime(5440): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:540) ERROR/AndroidRuntime(5440): at dalvik.system.NativeStart.main (Native Method) I am assuming that this third party callback is not executed in a safe way. Is there a paradigm I should follow to make sure that this is executed safely? For instance, does anyone know what MyLocationOverlay does to make sure its callback is executed safely for updating the overlay? I could not find source for MyLocationOverlay. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
