Get Current Location 0 in marshmallow where below 23 API its give exact current Location using fused Location

Question

I got current Location in Below 23 devices but getting (0.0,0.0) latitude and Longitude in 23 emulator device.

EDIT Currently I am using Fu

Answer 1

It maybe help you to known that.

I found that the Network provider not working in some android devices When you disable GPS because they're prevent access location data if GPS not enabled.

I've tried that on many devices 1. lenove k6 note (screen shot1 , screen shot2) 2. Xiomai mi 9t screen shot1 3. Google Pixel 1 & Pixel 2

so some devices need GPS enabled to access location from LocationManager.NETWORK_PROVIDER and you can't get location data without enable GPS

Answer 2

I got exact problem after some debugging and searching

GoogleAPIclient onConnected() not called so it called onConnectionFailed() method

In that Method I found error code it was 2 it mean REQUIRED PLAY SERVICE UPDATE

so I change play service in gradle file same as Device Playservice version so I get Current Location

I post Some code Here:

private synchronized void buildGoogleApiClient() {
 Log.i("TAG", "Building GoogleApiClient");
    mGoogleApiClient = new GoogleApiClient.Builder(getActivity().getApplicationContext())
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(LocationServices.API)
            .build();
    createLocationRequest();}

private void createLocationRequest() {
    Log.i("TAG", "CreateLocationRequest");
    mLocationRequest = new LocationRequest();
    long UPDATE_INTERVAL = 10 * 1000;
    mLocationRequest.setInterval(UPDATE_INTERVAL);
    long FASTEST_INTERVAL = 10000;
    mLocationRequest.setFastestInterval(FASTEST_INTERVAL);
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    builder = new LocationSettingsRequest.Builder()
            .addLocationRequest(mLocationRequest);
    //**************************
    builder.setAlwaysShow(true); //this is the key ingredient
    //**************************

}

private void startLocationUpdates() {

    Log.i("TAG", "StartLocationUpdates");

    if (Build.VERSION.SDK_INT >= 23) {
        if (ContextCompat.checkSelfPermission(getActivity().getApplicationContext(), Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED && ContextCompat.checkSelfPermission(getActivity().getApplicationContext(), Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling

                    mLocationRequest, this);

        }
    } else {

}

            // Note that this can be NULL if last location isn't already known.

                Log.d("DEBUG", "current location: " + mCurrentLocation.toString());
                currentlatitude = mCurrentLocation.getLatitude();
                currentlongitude = mCurrentLocation.getLongitude();
            } else {
                startLocationUpdates();
            }


        }
    } else {
        mCurrentLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);

        // Note that this can be NULL if last location isn't already known.
        if (mCurrentLocation != null) {

            currentlongitude = mCurrentLocation.getLongitude();
        }
        // Begin polling for new location updates.
        startLocationUpdates();

Answer 3

Add these permission in your androidmanifest.xml

then go to setting-----> Apps-----> Your App--->Grant location permission

<uses-permission-sdk-23   android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission-sdk-23 android:name="android.permission.ACCESS_FINE_LOCATION"/>

You can also add run time permissions. http://developer.android.com/intl/es/training/permissions/requesting.html

Now where ever you want to set your location in Activity add this

 // create class object
    gps = new GPSTracker(ImageUpload.this);
    // check if GPS enabled
    if (gps.canGetLocation()) {
        double latitude = gps.getLatitude();
        double longitude = gps.getLongitude();

        tv.setText("Latitude:" + latitude + ", Longitude:" + longitude);

    } else {
        // can't get location
        // GPS or Network is not enabled
        // Ask user to enable GPS/network in settings
        gps.showSettingsAlert();
    }
