Step 1: create new project
Step 2: In file AndroidManifest.xml

After line:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapplication">

Add:

<uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

Step 3: right click com.example.myapplication -> New -> Java Class with name GPS

android new java class

package com.example.myapplication;

    }

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
}

Step 4: in file content_main.xml add

<TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:textColor="#ff0000"
        android:text="TUTORIALSPOTS.COM" />

    <Button
        android:id="@+id/btn"
        android:text="Show your location"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true" />

Step 5: in file MainActivity.java

After line public class MainActivity extends AppCompatActivity { add

    public Button btn;
    public GPS gps;

in method onCreate add:

btn = (Button) findViewById(R.id.btn);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                gps = new GPS(MainActivity.this);
                if(gps.canGetLocation()){
                    double latitude = gps.getLatitude();
                    double longitude = gps.getLongitude();
                    Toast.makeText(getApplicationContext(),"Lat: " + latitude + ";\nLong: " + longitude + ";",Toast.LENGTH_LONG).show();
                }else{
                    Toast.makeText(getApplicationContext(),"Can't get Location by using GPS;",Toast.LENGTH_LONG).show();
                }
            }
        });

Done, now you can test your application.

Step 6: Start a genymotion virtual device

Then click icon Run and select your virtual device then click OK.

emulate with genymotion

Step 7: Genymotion set GPS location:

Click icon GPS then you can set your location you like. Then close this dialog.

genymotion set gps location

Result:

genymotion for gps location
