Hi all I wrote an app that gets and displays your location on a map. I am using the Google Maps service to render the map. The app has been live for less than two hours and I have received 33 crash reports (using ACRA).
I have been able to recreate the problem. The app works fine if the GPS is off but if it is switched on the app force closes. The stack trace reads: java.lang.NullPointerException at com.raghavsood.findme.MyPositionOverlay.draw(MyPositionOverlay.java:37) at com.google.android.maps.Overlay.draw(Overlay.java:179) at com.google.android.maps.OverlayBundle.draw(OverlayBundle.java:45) at com.google.android.maps.MapView.onDraw(MapView.java:494) at android.view.View.draw(View.java:6818) at android.view.ViewGroup.drawChild(ViewGroup.java:1640) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1367) at android.view.ViewGroup.drawChild(ViewGroup.java:1638) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1367) at android.view.View.draw(View.java:6821) at android.widget.FrameLayout.draw(FrameLayout.java:354) at android.view.ViewGroup.drawChild(ViewGroup.java:1640) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1367) at android.view.ViewGroup.drawChild(ViewGroup.java:1638) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1367) at android.view.View.draw(View.java:6821) at android.widget.FrameLayout.draw(FrameLayout.java:354) at com.android.internal.policy.impl.PhoneWindow$DecorView.draw(PhoneWindow.java:1944) at android.view.ViewRoot.draw(ViewRoot.java:1432) at android.view.ViewRoot.performTraversals(ViewRoot.java:1174) at android.view.ViewRoot.handleMessage(ViewRoot.java:1752) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:123) at android.app.ActivityThread.main(ActivityThread.java:4632) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:521) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:858) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616) at dalvik.system.NativeStart.main(Native Method) I don't know why there is a NullPointerException exception at MyPositionOverlay on line 37. The line in question reads: Double latitude = location.getLatitude()*1E6; The same code works fine if GPS is off. The app is https://market.android.com/details?id=com.raghavsood.findme Does anyone know what could be causing this and how to fix it?
