从按钮按下崩溃调用的Google地图布局

我正在尝试在Android应用程序中实现Google Maps API。当谷歌地图单独在一个应用程序中时，这很好用但是当我尝试通过另一个布局中的按钮点击打开包含地图的布局时，它会在行崩溃：setContentView（R.layout.activity_maps）;在mapsactivity.java中。

这是用于调用地图布局的函数：

public void runSSH(View v) {

    Intent intent = new Intent(this, MapsActivity.class);
    startActivity(intent);
}

mapsactivity.java是由AndroidStudio自动生成的，但我仍然会把它放在这里：

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

private GoogleMap mMap;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);
}


@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;

    // 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));
}
}

这里是Activitymaps.xml（也是自动生成的）：

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

我确实在清单和google_maps_api.xml

中添加了API密钥 
<meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="MYKEY-AIzaSyCf0-a3jUzVrL4PJwCo1q6W60YTxu-U7F0" />
<meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="@string/google_maps_key" />




<string name="google_maps_key" templateMergeStrategy="preserve" translatable="false">
    AIzaSyCf0-a3jUzVrL4PJwCo1q6W60YTxu-U7F0
</string>

以下是跟踪日志：

请帮帮我，我已经坚持了2天了。我是Android开发的初学者，可能有一些我错过的东西。

提前致谢

答案 0 :(得分：0)

问题是：

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 <application> element of AndroidManifest.xml

即时 

<meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="MYKEY-AIzaSyCf0-a3jUzVrL4PJwCo1q6W60YTxu-U7F0" />
<meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="@string/google_maps_key" />

仅限使用 

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