Question

所以我目前正在尝试开发一款需要谷歌地图API的应用。每当我尝试加载地图时，应用程序我将我的地图实现为片段类的子类：

package io.github.danisharsalan.meetupmarker;

import android.content.Context;
import android.net.Uri;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.MapView;
import com.google.android.gms.maps.MapsInitializer;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.model.CameraPosition;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;


public class MapActivityFragment extends Fragment {

MapView mMapView;
private GoogleMap googleMap;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_map_activity, container, false);

    mMapView = (MapView) rootView.findViewById(R.id.mapView);
    mMapView.onCreate(savedInstanceState);

    mMapView.onResume(); //needed to make map display immediately

    try{
        MapsInitializer.initialize(getActivity().getApplicationContext());
    } catch (Exception e){
        e.printStackTrace();
    }

    mMapView.getMapAsync(new OnMapReadyCallback() {
        @Override
        public void onMapReady(GoogleMap mMap) {
            googleMap = mMap;

            // For showing a move to my location button
            //googleMap.setMyLocationEnabled(true);

            // For dropping a marker at a point on the Map
            LatLng sydney = new LatLng(-34, 151);
            googleMap.addMarker(new MarkerOptions().position(sydney).title("Marker Title").snippet("Marker Description"));

            // For zooming automatically to the location of the marker
            CameraPosition cameraPosition = new CameraPosition.Builder().target(sydney).zoom(12).build();
            googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
        }
    });


    return rootView;
}

@Override
public void onResume(){
    super.onResume();
    mMapView.onResume();
}

@Override
public void onPause(){
    super.onPause();
    mMapView.onPause();
}

@Override
public void onDestroy(){
    super.onDestroy();
    mMapView.onDestroy();
}

@Override
public void onLowMemory(){
    super.onLowMemory();
    mMapView.onLowMemory();
}


}'

这是xml文件，标题为fragment_map_activity.xml：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="io.github.danisharsalan.meetupmarker.MapActivityFragment">

<!-- TODO: Update blank fragment layout -->

<com.google.android.gms.maps.MapView
    android:id="@+id/mapView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

</FrameLayout>

logcat给了我这个问题：

如何修复api密钥问题？谢谢。

编辑：事实证明，我只是错过了我应该被引用的API密钥。我对创建低质量问题表示歉意

看起来Google Maps API密钥未添加到AndroidManifest文件中。您可以从here

获取Google Maps API密钥

在结束标记</application >

之前插入API密钥，如下所示

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