谷歌地图API v2未加载..昨天工作不错

Question

我知道这是一个被问到的问题，但我有这种奇怪的行为。没有崩溃，但地图不再加载。

我正在尝试将谷歌地图用于我的Android应用程序。我昨天设法加载了我的地图，但今天当我尝试运行该应用程序时，我收到了以下错误：

08-01 10:40:50.374: I/Google Maps Android API(5605): Failed to contact Google servers. Another attempt will be made when connectivity is established.
08-01 10:41:05.649: E/Google Maps Android API(5605): Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).

这是我尝试打开地图的Activty：

public class LocationActivity extends Activity {
    private GoogleMap map;
    private RelativeLayout cancel_btn;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
        getActionBar().hide();
        setContentView(R.layout.preview_location);
        cancel_btn = (RelativeLayout) findViewById(R.id.cancel_btn);
        cancel_btn.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                onBackPressed();
            }
        });
        map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
                .getMap();
        if (map != null) {
            retrieveLocation();
        } else {
        }
    }
    @Override
    public void onBackPressed() {
        map.clear();
        super.onBackPressed();
    }
    private void retrieveLocation() {
        Intent intent = getIntent();
        String staddress = intent.getStringExtra("location");
        Geocoder geocoder = new Geocoder(this, Locale.US);
        try {
            List<Address> loc = geocoder.getFromLocationName(staddress, 5);
            double latitude = loc.get(0).getLatitude();
            double longitude = loc.get(0).getLongitude();
            map.addMarker(new MarkerOptions().position(
                    new LatLng(latitude, longitude)).title(staddress));
            map.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(latitude, longitude), 12));
            // Zoom in, animating the camera.
            map.animateCamera(CameraUpdateFactory.zoomTo(12), 2000, null);
        } catch (IOException e) {
            Log.e("IOException", e.getMessage());
            Toast.makeText(this, "IOException:  " + e.getMessage(), Toast.LENGTH_LONG).show();
        }
    }
}

以及XML:

<fragment
        android:layout_weight="6"
        android:id="@+id/map"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        class="com.google.android.gms.maps.MapFragment"/>

清单XML:

我今天更新了我的API密钥仍然没有结果。。。有什么想法吗？

兄弟，您是否根据您的Google Api密钥授予所有权限并更改包名。现在您必须粘贴您的清单文件代码。
