lollipop and marshmallow gps issue not able to fetch longitude and latitude values but same code working on api below 21
<p><strong>I have been through lot of questions</strong> in stack overflow **but not able to solve my problem its not any spam question ** </p>

<p>Hi everyone i am having a problem related to latitude and longitude values </p>

<p>iam able to fetch values in all api till Android 5.0 but from 5.1 i am facing problem i am not able to fetch values</p>

<p>This is what the code i am using </p>

<p><strong>i have only added code which i am using to fetch permission</strong></p>

<pre><code>   if (ContextCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED &amp;&amp; ActivityCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);

    } else {
        Toast.makeText(mContext, "You need have granted permission", Toast.LENGTH_SHORT).show();
        gps = new GPSTracker(mContext, MainActivity.this);

        // Check if GPS enabled
        if (gps.canGetLocation()) {

            getlatitude = gps.getLatitude();
            getlongitude = gps.getLongitude();

            // \n is for new line
            Toast.makeText(getApplicationContext(), "Your Location is - \nLat: " + getlatitude + "\nLong: " + getlongitude, Toast.LENGTH_LONG).show();
        } else {
            // Can't get location.
            // GPS or network is not enabled.
            // Ask user to enable GPS/network in settings.
            gps.showSettingsAlert();
        }
    }
</code></pre>

<p>And then </p>

<pre><code>  @Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);

    switch (requestCode) {
        case 1: {
            // If request is cancelled, the result arrays are empty.
            if (grantResults.length &gt; 0
                    &amp;&amp; grantResults[0] == PackageManager.PERMISSION_GRANTED) {


                gps = new GPSTracker(mContext, MainActivity.this);

                // Check if GPS enabled
                if (gps.canGetLocation()) {

                    getlatitude = gps.getLatitude();
                    getlongitude = gps.getLongitude();

                    // \n is for new line
                    Toast.makeText(getApplicationContext(), "Your Location is - \nLat: " + getlatitude + "\nLong: " + getlongitude, Toast.LENGTH_LONG).show();
                } else {
                    // Can't get location.
                    // GPS or network is not enabled.
                    // Ask user to enable GPS/network in settings.
                    gps.showSettingsAlert();
                }

            } else {

                // permission denied, boo! Disable the
                // functionality that depends on this permission.

                Toast.makeText(mContext, "You need to grant permission", Toast.LENGTH_SHORT).show();
            }
            return;
        }
    }
}
</code></pre>

<p>but still i am getting </p>

<p>Toast as <strong>Lat 0 Long 0</strong></p>

<p>Info regarding gradle</p>

<p>i am <strong>targeting sdk 23</strong> version</p>

<p>After searching few questions i came to know that we need permission to get these values can any one clearly help me in this regard</p>

<p><strong>Manifest File</strong></p>

<p>i have added</p>

<pre><code> &lt;uses-permission android:name="android.permission.INTERNET" /&gt; 
 &lt;uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/&gt;
 &lt;uses-permission android:name="android.permission.ACCESS_FINE_LOCATION/&gt;
</code></pre>

<p>and also 
Network provider permission</p>

<p>**</p>

<blockquote>
  <p>Now i have added the new code according to changes in below</p>
</blockquote>

<p>** </p>

<pre><code>    public class MainActivity extends Activity {



    Context context;

    double latitude_user,longitude_user;

    public static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 1;

    String[] permissions= new String[]{

            gps = new GPSTracker(context);

            latitude_user= gps.getLatitude();
