MapsActivity.javaコード：

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback { 

    private GoogleMap mMap; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState);

     // Obtain the SupportMapFragment and get notified when the map is ready to be used. 
     SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager() 
       .findFragmentById(R.id.map);

     // Add a marker in Sydney and move the camera 
     LatLng sydney = new LatLng(-34, 151); 
     mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney")); 
     mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));

Answer 1

• まずチェックし、GoogleマップのAndroid APIは、Googleの開発者で有効になっていますコンソール
• チェックプロジェクトのパッケージ名は、右のGoogleのdevのコンソールである
• その後、あなたは（デバッグ/リリース）あなたは、あなたがする必要があるタイプを解放したい場合は、右のキーはあなたのリソースに追加され
• チェックをしたいマップの種類を確認しますデバッグおよびリリースファイルにも追加してください（キーを追加すると、リベースタイプが必要な場合、デバッグファイルは機能しません）
• 次に、SHAキーがPCおよび正しいキーであることを確認します開発者に両方のキーを追加できます コンソール

Answer 2

メタデータトークン間違っ：

Caused by: java.lang.RuntimeException: The API key can only be specified once. It is recommended that you use the meta-data tag with the name: com.google.android.geo.API_KEY in the element of AndroidManifest.xml at maps.y.k.a(Unknown Source) at maps.v.c.a(Unknown Source) at 

あなたが置く：

<meta-data 
     android:name="com.google.android.maps.v2.API_KEY" 
     android:value="@string/google_maps_key" /> 

はそれを変更しよう：

<meta-data 
      android:name="com.google.android.geo.API_KEY" 
      android:value="@string/google_maps_key" /> 

これを試してみてください。
