Answer 1

posting simple solution with code.

add permissions inside AndroidManifest.xml file

if you app is marshmallow compatible then check run time permission.

add dependency inside gradle file:

compile 'com.google.android.gms:play-services:9.2.0'

implements this two interface in you activity

GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener

and

create googleapiclient object like this in oncreate:

mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();

and make this on start activity

mGoogleApiClient.connect();

here we go on result callback of location on this override method.

public void onConnected(@Nullable Bundle bundle) {
    Location mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
    if (mLastLocation != null) {
        Log.e(TAG, "onConnected: " + String.valueOf(mLastLocation.getLatitude()) + ":" + String.valueOf(mLastLocation.getLongitude()));
    } else {
        Toast.makeText(getApplicationContext(), "Your Location Not Found", Toast.LENGTH_LONG).show();
    }
}

full code of activity is something like that:

public class LocationActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {

private static final String TAG = LocationActivity.class.getSimpleName();

private GoogleApiClient mGoogleApiClient;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_location);


    // Create an instance of GoogleAPIClient.
    if (mGoogleApiClient == null) {
        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
    }
}

@Override
protected void onStart() {
// connect googleapiclient
    mGoogleApiClient.connect();
    super.onStart();
}

@Override
protected void onStop() {
// disconnect googleapiclient
    mGoogleApiClient.disconnect();
    super.onStop();
}

@Override
public void onConnected(@Nullable Bundle bundle) {
    Location mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
    if (mLastLocation != null) {
    // here we go you can see current lat long.
        Log.e(TAG, "onConnected: " + String.valueOf(mLastLocation.getLatitude()) + ":" + String.valueOf(mLastLocation.getLongitude()));
    }
}

@Override
public void onConnectionSuspended(int i) {

}

@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {

}}

p.s. googleapiclient is not working in emulator without play services, so you have to test it on real devices. please make sure gps is enable on that device.

if you want to use traditional method for get location then try this tutorial. http://www.androidhive.info/2012/07/android-gps-location-manager-tutorial/
