Question

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) {

    }


}

Answer 1

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.

Answer 2

The thing that seems wrong to me is mLocationClient.connect(); inside onConnected() method because onConnected() is a method of GooglePlayServicesClient.ConnectionCallbacks interface which calls onConnected() when LocationClient gets conntected to google services and this happens after the call to mLocationclient.connect() method. You should use mLocationClient.connect() method somewhere else like onResume() or onStart().
