java - 谷歌地图 API 出现 DexIndexOverflowException

Question

我想制作一个使用谷歌地图 API 的应用程序，我从一个打开谷歌地图 Activity 的简单应用程序开始。 (我从 SDK 管理器下载 google play 服务)。我认为这是一个非常基本的程序，但是当我尝试运行我的应用程序时出现错误。

这是我程序的代码，也是Android Studio产生的错误。

错误:

Error:Execution failed for task ':app:transformClassesWithDexForDebug'. > com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexIndexOverflowException: method ID not in [0, 0xffff]: 65536

代码:

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {     
private GoogleMap mMap;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);
}


/**
 * Manipulates the map once available.
 * This callback is triggered when the map is ready to be used.
 * This is where we can add markers or lines, add listeners or move the camera. In this case,
 * we just add a marker near Sydney, Australia.
 * If Google Play services is not installed on the device, the user will be prompted to install
 * it inside the SupportMapFragment. This method will only be triggered once the user has
 * installed Google Play services and returned to the app.
 */
@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));
}
}

这是导入所有 Google Play 服务时的常见错误，如果这样做，很容易达到 65k 方法限制。

如果你的 build.gradle 中有这个:

compile 'com.google.android.gms:play-services:10.0.1'

将其替换为:

compile 'com.google.android.gms:play-services-maps:10.0.1'
