Android MapView v2 Context Issues and Memory Leak

由 你离开我真会死。 提交于 2019-12-04 16:07:50
I'm using MapView v2 in my application (not MapFragment ) and it's causing a memory leak. The leak occurs when I pass the Activity context to the MapView constructor. If I pass the Application Context to the MapView constructor the memory leak goes away, however the MapView starts performing badly when I scroll the ScrollView it's in. Here's a snapshot of where the leak is happening: The relevant code in MapView is: public class MapView extends android.widget.FrameLayout { private final com.google.android.gms.maps.MapView.b gD; static class b extends com.google.android.gms.dynamic.a<com.google

Can't receive LocationClient's location updates after screen gone off

由 本秂侑毒 提交于 2019-12-04 08:05:34
I'm trying to write a simple Android Service that runs in background and receives location updates from LocationClient (Google Map API Android V2). The problem is that when the screen go off, my Service doesn't receives anymore location updates. I tried to check if the service was active, even with screen off, and it does (I have a TimerTask scheduling a log). When screen is on I can receive location updates, but when screen goes off I see only TimerTask's logs and I don't receive any location update. Waking up screen turns on location updates again. How can this be solved? Here is my simple
