当我在真实设备上运行应用程序时出现此错误。

Main_Activity.java,

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    int chkGooglePlayServices = GooglePlayServicesUtil
            .isGooglePlayServicesAvailable(Context);
    if (chkGooglePlayServices != ConnectionResult.SUCCESS) {
        GooglePlayServicesUtil.getErrorDialog(chkGooglePlayServices,
                (Activity) Context, 1122).show();
    } else {
        SupportMapFragment sfm = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mMap = sfm.getMap();

        mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
        lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        Criteria criteria = new Criteria();
        criteria.setAccuracy(Criteria.ACCURACY_FINE);
        // Location Update
        LocationListener listener = new LocationListener() {
            @Override
            public void onLocationChanged(Location location) {
                mMap.clear();
                final CameraPosition cameraPosition = new CameraPosition.Builder()
                        .target(new LatLng(location.getLatitude(), location
                                .getLongitude())).zoom(14.0f).build();
                final CameraUpdate cameraUpdate = CameraUpdateFactory
                        .newCameraPosition(cameraPosition);
                mMap.moveCamera(cameraUpdate);
            }

            AlertDialog.Builder dialog = new AlertDialog.Builder(Context)
                    .setTitle(R.string.RemindEnableGps);
            AlertDialog alert = dialog.create();

            @Override
            public void onProviderDisabled(String provider) {
                alert.setCanceledOnTouchOutside(false);
                alert.setCancelable(true);
                alert.show();

            }

            @Override
            public void onProviderEnabled(String provider) {
                alert.dismiss();

            }

            @Override
            public void onStatusChanged(String provider, int status,
                    Bundle extras) {
            }
        };

        lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0,
                listener);
        final Location mLocation = lm
                .getLastKnownLocation(LocationManager.GPS_PROVIDER);

        /*final CameraPosition cameraPosition = new CameraPosition.Builder()
                .target(new LatLng(mLocation.getLatitude(), mLocation
                        .getLongitude())).zoom(14.0f).build();
        final CameraUpdate cameraUpdate = CameraUpdateFactory
                .newCameraPosition(cameraPosition);
        mMap.moveCamera(cameraUpdate);*/
    }

}

这是我的主要文件，

        android:value="Given my signed key" />

   </application>

</manifest>

activity_main.xml，

 <?xml version="1.0"?>


<fragment 
    android:id="@+id/map"
    android:layout_width="fill_parent"

    android:layout_marginTop="60dp"
    class="com.google.android.gms.maps.SupportMapFragment"
    android:clickable="true" />

</RelativeLayout>

我已经导入了应用程序所需的 Google Play 库。地图对象不为空。但在 logcat 中它显示“Google maps Api v2 Failed to load map. could not connect to google servers”

我错过了什么？请任何人帮助！这要死我了！！

您的清单意味着您已将签名的 api 密钥作为 google api 密钥输入，因此我假设您通过在设备上安装签名的 apk 来测试这一点，而不是通过 eclipse 运行使用调试密钥签名的应用程序。这个对吗？

像这样的 API 访问问题通常归结为 api 密钥的输入错误，或哈希过程中的错误。

我会确保您的清单中的密钥是正确的。
