Question

我在片段中有一个Map。直到现在，它显示正确。现在，我看到Google徽标，+ / - 按钮和带正方形的灰色表面（它不是典型的空白背景），但我看不到地图。

logcat连续显示：

编辑 - 代码添加：

private void checkMap() {
    if (mMap == null) {
        /*Try to obtain the map from the SupportMapFragment*/
        mMap = ((SupportMapFragment) getActivity().getSupportFragmentManager().findFragmentById(R.id.map))
                .getMap();
        /*Check if we were successful in obtaining the map.*/
        if (mMap != null) {
            initMap();
        }
    }
}

private void initMap() {
    /*Get location*/
    LocationManager locationManager = (LocationManager) getActivity().getSystemService(Context.LOCATION_SERVICE);
    /*Set criteria*/
    Criteria criteria = new Criteria();
    criteria.setAccuracy(Criteria.ACCURACY_FINE);
    String provider = locationManager.getBestProvider(criteria, true);
    /*Get last known location if exists*/
    defaultLocation = locationManager.getLastKnownLocation(provider);
    /*If last known location doesn't exist request a single update*/
    if (defaultLocation == null) {
        locationManager.requestSingleUpdate(criteria, new LocationListener() {
            @Override
            public void onLocationChanged(Location location) {
                defaultLocation = location;
            }
            @Override
            public void onProviderEnabled(String provider) {
            }
            @Override
            public void onProviderDisabled(String provider) {
            }
            @Override
            public void onStatusChanged(String provider, int status, Bundle extras) {
            }
        }, getActivity().getMainLooper());
    }
    /*Move camera*/
    if (defaultLocation != null) {
        mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(
                new LatLng(defaultLocation.getLatitude(), defaultLocation.getLongitude()), 5));
    }
}

Answer 1

最后，我得到了一个解决方案。如果您使用私有密钥库来应用API_KEY，则无法使用eclipse上载和安装应用程序，因此，您必须使用调试密钥。如果您想使用私钥库查看地图，则需要自行将.apk文件上传到您的设备并进行安装。

Answer 2

请尝试以下方式

首先检查生成的API密钥是否正确且IT是否有效API CONSOLE
1. 添加签名许可。
2. 添加gsf的权限
3. 检查SDK最低版本和最高版本
4. 如果您在模拟器上运行，那么您需要从cmd pormt安装这两个apk文件。下载链接...

Open the AVD
Execute this in the terminal / cmd

adb -e install com.google.android.gms.apk
