问题
Here is my problem. I would like to open googleMaps activity from another activity, bind to a service, and recieve data from tcp server.
I open googleMaps like this:
Intent intent = new Intent(GpsInterfaceActivity.this,MapActivity.class);
startActivity(intent);
Google maps crashes here.
I used to open it like this:
String uriBegin = "geo:" + DeviceLatitude + "," + DeviceLongitude;
String query = DeviceLatitude + "," + DeviceLongitude;// + "(" + "device" + ")";
String encodedQuery = Uri.encode(query);
String uriString = uriBegin + "?q=" + encodedQuery + "&z=16";
Uri uri = Uri.parse(uriString);
Intent intent = new Intent(android.content.Intent.ACTION_VIEW, uri);
but i can't control google maps in it's activity, if i use this.
MapActivity:
public class MapActivity extends Activity {
// Google Map
private GoogleMap googleMap;
private IncomingData mTask;
private int flag = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.map_activity);
GoogleMap map = ((MapFragment) getFragmentManager()
.findFragmentById(R.id.map)).getMap();
LatLng sydney = new LatLng(-33.867, 151.206);
map.setMyLocationEnabled(true);
map.moveCamera(CameraUpdateFactory.newLatLngZoom(sydney, 13));
map.addMarker(new MarkerOptions()
.title("Sydney")
.snippet("The most populous city in Australia.")
.position(sydney));
}
map activity xml:
<?xml version="1.0" encoding="utf-8"?>
