I try to get current location, following the guide from http://developer.android.com/training/location/retrieve-current.html
my google play service is up, however my locationclient still can't connected, and getting those error when i running the program. (PS: previously my location code is working, but now can't, strange)
here you go
package com.example.Wifin;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GooglePlayServicesClient;
import com.google.android.gms.common.GooglePlayServicesUtil;
import com.google.android.gms.location.LocationClient;
import com.google.android.gms.location.LocationListener;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.Marker;
import com.google.android.gms.maps.model.MarkerOptions;
import android.app.Activity;
import android.location.Location;
import android.os.Bundle;
import android.util.Log;
import android.widget.Toast;
public class myMap extends Activity implements
GooglePlayServicesClient.ConnectionCallbacks,
GooglePlayServicesClient.OnConnectionFailedListener,LocationListener {
GoogleMap mMap;
LatLng Current;
Marker here;
LocationClient mLocationClient;
int resultCode;
Location mCurrentLocation;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_map);
resultCode =GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
if(ConnectionResult.SUCCESS == resultCode){
Log.d("Location Updates",
"Google Play services is available.");
}
else{
Toast.makeText(this, "Google Play Service Error " + resultCode,Toast.LENGTH_LONG).show();
}
mLocationClient = new LocationClient(this, this, this);
mCurrentLocation = mLocationClient.getLastLocation();
Current = new LatLng(mCurrentLocation.getLatitude(),mCurrentLocation.getLongitude());
mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
here = mMap.addMarker(new MarkerOptions()
.position(Current)
.title("you're here!")
.snippet("Connect to home2, Signal Strenght -20dBm")
.icon(BitmapDescriptorFactory.fromResource(R.drawable.testmarker)));
}
@Override
public void onConnectionFailed(ConnectionResult result) {
}
@Override
public void onConnected(Bundle connectionHint) {
mLocationClient.connect();
}
@Override
public void onDisconnected() {
}
@Override
public void onLocationChanged(Location arg0) {
}
}

look here
Not connected. Call connect() and wait for onConnected() to be called.
You should call .connect()
.. then do the method in onConnected()
.
Because if it's not connected, and you are trying to access the internet it'll crash.
