我的代码编译成功。但谷歌地图无法启动。问题是什么？我尝试编译时会出现此错误。但编译很好，它无法启动谷歌地图。

MapsActivity.java

package kianyang.scbg;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class MapsActivity extends FragmentActivity{

    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.
      setUpMapIfNeeded();
    }

@Override
    protected  void onResume(){
    super.onResume();
    setUpMapIfNeeded();

}

    private  void setUpMapIfNeeded(){

        if(mMap==null){

            mMap=((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map))
                    .getMap();

            if(mMap!=null){
                setUpMap();
            }
        }




    }
    /**
     * 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.
     */
   private void setUpMap(){
       mMap.addMarker(new MarkerOptions().position(new LatLng(2.215035, 102.245443)).title("Marker"));
   }
}

这是我的清单文件。里面有另一个意图;只是忽略它。请帮助查看Google地图代码。

Answer 1

您似乎错过了.XML文件中的Google Maps API密钥（这允许您访问Google服务器）。用于为android设置地图的开发博客是Here，步骤＃4描述了如何获取密钥。

Answer 2

对于此错误，您可能会遗漏google-services.json com.google.gms.google-services，或者您错过了正确的插件build.gradle。如果您有compile com.google.android.gms:play-services:8.4.0行，请检查com.google.android.gms:play-services:8.4.0文件（8.4.0是最新版本，但可以是8.3.0或更低版本）。如果没有，您可以通过SDK Manager下载它。

注意：如果您使用json=str(MyTableData)进行进一步说明，则需要SD卡，请参阅link。
