根据谷歌文档，谷歌地图问题即使所有设置都是正确的

Question

我已经按照google map api documentation实现了google map。

活动代码在这里

public class GoogleMapActivity extends AppCompatActivity implements OnMapReadyCallback {
    private GoogleMap map;
    double latitude,longitude;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.fragment_map_layout);
        latitude = Double.parseDouble(getIntent().getExtras().getString("lat"));
        longitude =Double.parseDouble(getIntent().getExtras().getString("lng"));
             SupportMapFragment mapFragment =
                (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);

    }

    @Override
    public void onMapReady(GoogleMap map) {
        map.setMyLocationEnabled(true);
        CameraPosition cameraPosition = new CameraPosition.Builder().target(
                new LatLng(latitude, longitude)).zoom(12).build();

        map.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
        Marker marker = map.addMarker(new MarkerOptions()
                .position(new LatLng(latitude, longitude)));
        map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
    }
}

xml 布局

                </application>
</manifest>

我们还为谷歌地图键添加了 sha-1

结果屏幕（地图）

build.gradle 文件中 Google play 服务版本为 11.0.2

编译“com.google.android.gms:play-services-maps:11.0.2”

似乎代码、开发者控制台设置和清单设置都很完美。但我们无法理解冲突从何而来。 如果有人也遇到此类问题，请帮助我们解决它。 很多 +1 将不胜感激。

此代码在单独的项目中工作，以显示具有相同开发者控制台设置的地图。

Answer 1

在下面标记在您的清单文件中

 <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />
<meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="YOUR GOOGLE KEY" />

将您的谷歌地图密钥而不是“密钥”放在清单中，并确保您必须从谷歌开发者控制台启用 api。

Answer 2

E/Google Maps Android API: Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).

以上错误日志显示这是一个身份验证问题。

如果您已实施 SSL 证书，则在启动地图活动时可能会遇到主机名验证问题，从而限制您的 google map api。

验证主机名时需要允许 google map api。有关更多信息，请阅读以下文档。
