I am working on accessing the user current location and have gone through this tutorial Current location and this tutorial Current Location. Everything seems fine but latitude and longitude are not coming up in the TextView field.
Here is my code
@Keep
public class edit_information extends Fragment implements AdapterView.OnItemSelectedListener, GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener, LocationListener, ResultCallback<LocationSettingsResult> {
protected final static String TAG = "EditInformation";
private static final int MY_PERMISSIONS_ACCESS_LOCATION = 1;
private RadioGroup radioGroup;
private RadioGroup musicRadioGroup;
private RadioGroup decorRadioGroup;
protected static final int REQUEST_CHECK_SETTINGS = 0x1;
//The desired interval for location updates
public static final long UPDATE_INTERVAL_IN_MILLISECONDS = 10000;
//The fastest rate for active location updates
public static final long FASTEST_UPDATE_INTERVAL_IN_MILLISECONDS = UPDATE_INTERVAL_IN_MILLISECONDS / 2;
//Keys for storing activity state in bundle
protected static final String KEY_REQUESTING_LOCATION_UPDATES = "requesting-location-updates";
protected static final String KEY_LOCATION = "location";

These are permissions which I have added in manifest file
<uses-permission android:name = "android.permission.INTERNET" />
<uses-permission android:name = "android.permission.ACCESS_FINE_LOCATION" />
This is the xml code for latitude and longitude
<TextView
android:id="@+id/myLatitude"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textSize="15sp"
android:textColor="@color/cordinates_color"
/>
<TextView
android:id="@+id/myLongitude"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textSize="15sp"
android:textColor="@color/cordinates_color"
/>
I have added this line in build.gradle app level and sync the project compile 'com.google.android.gms:play-services:10.0.1'
I have been able to connect to GoogleApiClient but coordinates are not coming up. This is a glimpse of logcat

I am testing it on Android Marshmallow. Still unable to figure it out.
Can you help me out ?
Thank you
