我曾尝试使用之前Google_Play_SERVICE/SAMPLE通过使用所有可用选项提供的谷歌地图示例代码，它显示了以下日志。
01-14 17:58:39.773：E/Google Maps Android API(13114)：授权失败。
它向我展示了所有示例地图选项的空白屏幕。
现在我创建了一个新项目，这是它的完整代码：-
活动.java
public class MapActivity extends FragmentActivity
{
private Context context = this;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_map);
GoogleMap gMap = ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
int result = GooglePlayServicesUtil.isGooglePlayServicesAvailable(context);
Log.e("Maps", "Result int value::" + result);
switch (result) {
case ConnectionResult.SUCCESS:
Log.e("Maps", "RESULT:: SUCCESS");
break;
case ConnectionResult.DEVELOPER_ERROR:
Log.e("Maps", "RESULT:: DE");
break;
case ConnectionResult.INTERNAL_ERROR:
Log.e("Maps", "RESULT:: IE");
break;
case ConnectionResult.INVALID_ACCOUNT:
Log.e("Maps", "RESULT:: IA");
break;
case ConnectionResult.NETWORK_ERROR:
Log.e("Maps", "RESULT:: NE");
break;
case ConnectionResult.RESOLUTION_REQUIRED:
Log.e("Maps", "RESULT:: RR");
break;
case ConnectionResult.SERVICE_DISABLED:
Log.e("Maps", "RESULT:: SD");
break;
case ConnectionResult.SERVICE_INVALID:
Log.e("Maps", "RESULT:: SI");
break;
case ConnectionResult.SERVICE_MISSING:
Log.e("Maps", "RESULT:: SM");
break;
case ConnectionResult.SERVICE_VERSION_UPDATE_REQUIRED:
Log.e("Maps", "RESULT:: SVUR");
break;
case ConnectionResult.SIGN_IN_REQUIRED:
Log.e("Maps", "RESULT:: SIR");
break;
default:
break;
}
gMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
gMap.setMyLocationEnabled(true);
Log.e("Maps", "------EOC-------");
}
}

截屏
这是结果，带有缩放选项的空白屏幕，MapView 中没有地图。
我遵循了以下提到的每一个步骤：-
