android - map 未显示

Question

我在 fragment 中有一个 map 。到目前为止，它显示正确。现在，我看到了 Google Logo 、+/- 按钮和带方 block 的灰色表面(这不是典型的空白背景)，但我看不到 map 。

logcat 不断显示:

编辑- 添加代码:

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));
    }
}

我终于找到了解决方案。如果您使用私有(private) keystore 来应用 API_KEY，您将无法使用 eclipse 上传和安装应用程序，为此，您必须使用调试 key 。如果您想使用私有(private) keystore 查看 map ，您需要自行将 .apk 文件上传到您的设备并进行安装。
