安卓谷歌地图无法加载地图

androidgoogle-maps

我在谷歌上搜索了这个错误，并且有很多人遇到了同样的问题，但是他们提供的所有解决方案都对我无效。希望您知道我不擅长在该站点上提问，所以如果您能提供任何改进我的问题的反馈，那将不胜感激。谢谢。
问题是google地图不会加载地图，只会显示一个灰色屏幕和左下角的google标志。
以下是我的java文件与地图：

可能是您的 API 密钥出现了问题。 - SripadRaj
不，这不是我的 API 密钥，我在另一个应用程序中使用它仍然有效。 - Rakan Habab
Logcat 提供的是设备或模拟器日志，而不是这个特定类的日志。 - Dhaval Jardosh

您需要完成两件事情：
  1. 启用 Google Android Maps API
  2. 在onCreate中添加代码到onMapReady并调用回调函数

如何启用 Google Android Maps API

  • 登录到您的应用程序，网址为 https://console.developers.google.com/
  • 点击 启用API和服务
  • 点击 Google Maps Android API
  • 点击 启用

其次，请将以下代码添加到您的DetailActivity.java文件中：

public class DetailActivity extends AppCompatActivity implements OnMapReadyCallback {

    private static final int DIALOG_REQUEST = 9001;

    public GoogleMap mMap;

    public void onMapReady(GoogleMap map) {

        mMap = map;

        if (servicesOK() /*&& initMap()*/) {

            //Geocoder gc = new Geocoder(this);
            //List<Address> list;
            try {
                //list = gc.getFromLocationName(hotel.getAddress(), 1);
                //Address address = list.get(0);

                double lat = 0.6856979;
                double lng = 16.8795434;
                LatLng latLong = new LatLng(lat, lng);
//                CameraUpdate update = CameraUpdateFactory.newLatLngZoom(latLong, 5);
                Log.i("BEGINNING","Check this");
                mMap.moveCamera(CameraUpdateFactory.newLatLng(latLong));
                Log.i("Finishing","Check this");

                /*MarkerOptions options = new MarkerOptions()
                        .title(getString(R.string.landon_hotel) + ", " + city)
                        .position(new LatLng(lat, lng));
                mMap.addMarker(options);*/
                //onMapReady(mMap);

            } /*catch (IOException e) {
                Toast.makeText(this, getString(R.string.error_finding_hotel), Toast.LENGTH_SHORT).show();
            }*/ catch (Exception e) {
                Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
                Log.d("Check this->", e.getMessage());
            }



        }

    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_detail_with_map);
        /*
        String city = getIntent().getStringExtra("city");
        setTitle(getString(R.string.landon_hotel) + ", " + city);
        Hotel hotel = DataProvider.hotelMap.get(city);
        if (hotel == null) {
            Toast.makeText(this, getString(R.string.error_find_hotel) + ": "
                    + city, Toast.LENGTH_SHORT).show();
            return;
        }
        TextView cityText = (TextView) findViewById(R.id.cityText);
        cityText.setText(hotel.getCity());
        TextView neighborhoodText = (TextView) findViewById(R.id.neighborhoodText);
        neighborhoodText.setText(hotel.getNeighborhood());
        TextView descText = (TextView) findViewById(R.id.descriptionText);
        descText.setText(hotel.getDescription() + "\n");
        */


        SupportMapFragment mapFrag =
                (SupportMapFragment) getSupportFragmentManager()
                        .findFragmentById(R.id.map);
//            mMap = mapFrag.getMap();
        mapFrag.getMapAsync(this);

    }

    public boolean servicesOK() {
        int result = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);

        if (result == ConnectionResult.SUCCESS) {
            return true;
        } else if (GooglePlayServicesUtil.isUserRecoverableError(result)) {
            Dialog dialog = GooglePlayServicesUtil.getErrorDialog(result, this, DIALOG_REQUEST);
            dialog.show();
        } else {
            Toast.makeText(this, getString(R.string.error_connect_to_services), Toast.LENGTH_LONG).show();
        }
        return false;
    }

//    private boolean initMap() {
//        if (mMap == null) {

//        }
//        return (mMap != null);

尝试在灰色屏幕上缩放，地图是否正在加载？ - Dhaval Jardosh

把它放在Github上并给我链接，我会检查它。 - Dhaval Jardosh
这是我的Github项目链接。地图代码在DetailActivity.java文件中，我已经添加了大量注释，但你可以从原始帖子中复制代码并再次尝试。最后一件事，我已经删除了API密钥，所以你需要自己添加一个。 - Rakan Habab

@RakanHabab，请查看我的更新并让我知道你是否也能解决它。 - Dhaval Jardosh

是的，请这样做，它对我有效。使用新的logcat更新问题。 - Dhaval Jardosh

在我的情况下，问题在于主机名验证。如果您有自定义的全局主机名验证器，请确保验证不会丢弃Google主机名。

HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier(){

    public boolean verify(String hostname, SSLSession session){

        //accept google hostnames or redesign your security policy
    }
});

有时候，这可能是一个简单的问题。您需要检查您的清单文件。它应该包含以下内容：
<meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="@string/google_map_key" />
