Question

我想创建一个使用Google Maps API的应用程序，我开始使用一个简单的应用程序来打开谷歌地图活动。（我从SDK Manager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错。

这是我的程序代码，也是Android Studio生成的错误。

错误：

错误：任务执行失败＆＃39;：应用程序：transformClassesWithDexForDebug＆＃39 ;. ＆GT; com.android.build.api.transform.TransformException： com.android.ide.common.process.ProcessException： java.util.concurrent.ExecutionException： com.android.dex.DexIndexOverflowException：方法ID不在[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));
}
}

Answer 1

导入所有Google Play服务时出现常见错误，如果这样做，很容易达到65k方法限制。

如果你在build.gradle中有这个：

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

替换为：

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

有关详细信息，请参阅the documentation。

Answer 2

在清单文件中添加互联网权限

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

还要确保打开手机上的互联网和位置

Answer 3

在添加Internet权限后，尝试将multiDexEnabled true添加到您的app build.gradle文件中。

defaultConfig {
    multiDexEnabled true
}

DexIndexOverflowException使用Google Maps API
