我知道这是一个被问到又被问到的问题，但是我得到了这种奇怪的行为。没有崩溃，但地图不再加载。
我正在尝试将 Google 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活动：
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();
}
}
}
和 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"

我今天更新了我的 API 密钥仍然没有结果......有什么想法吗？
