Answer 1

Points to be noted:

1. You are using an older version of Google Map which is no longer supported.

2. You might be using the wrong API keys.

3. You haven't added the proper permissions on the manifest file.

4. Make sure you have included the Google Play Services library to your project.

Possible solutions,

A. Add a support map fragment in your xml,

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/map"
    tools:context=".MapsActivity"
    android:name="com.google.android.gms.maps.SupportMapFragment" />

B. Use the support map fragment in your activity and implement onMapReadyCallback

public class MapPane extends Activity implements OnMapReadyCallback {

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

        MapFragment mapFragment = (MapFragment) getFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
    }

    @Override
    public void onMapReady(GoogleMap map) {
        LatLng sydney = new LatLng(-33.867, 151.206);

        map.setMyLocationEnabled(true);
        map.moveCamera(CameraUpdateFactory.newLatLngZoom(sydney, 13));
    }
}

C. Add proper permissions on the manifest file,

    <!-- Creating Permission to receive Google Maps -->
    <permission
        android:name="com.example.app.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" />

    <!-- Permission to receive Google Maps -->
    <uses-permission android:name="com.example.app.permission.MAPS_RECEIVE" />

<meta-data
 android:name="com.google.android.gms.version"
 android:value="@integer/google_play_services_version" />
<meta-data
 android:name="com.google.android.maps.v2.API_KEY"
 android:value="YOUR_GOOGLE_MAP_APIKEY" />

D. To get a Google Maps API key follow the instructions here,
