I'm building a codename one mobile application and i need to fetch a blank google maps on which i can place icons showing my own coordinates (not places i can fetch through the google places api). 我正在构建一个代号为一个移动应用程序，我需要获取一个空白的Google地图，可以在该地图上放置显示自己坐标的图标（而不是我可以通过Google Places API获取的位置）。 How can i do that ? 我怎样才能做到这一点？ Since i don't want to fetch anything other than a blank map, i wonder if i need a webservice for that. 由于我不想获取空白地图以外的任何东西，因此我想知道是否需要网络服务。 I have read that instantiating the MapContainer would show me a blank google map but i am stil getting a osm map (on both the emulator and a real Android 4.4 device). 我已经读过实例化MapContainer会向我显示一个空白的Google地图，但是我仍然在获取osm地图（同时在模拟器和真实的Android 4.4设备上）。 I have already done all the procedures required to get a key and all the steps of the maps demo work fine for me. 我已经完成了获取密钥所需的所有过程，并且地图演示的所有步骤对我来说都可以正常工作。 Now what i need to know is how to be able to get a blank map. 现在我需要知道的是如何获得空白地图。

Thank you advance for the answers. 谢谢您提前提供答案。

You get OSM on the device as a fallback when initializing the native map failed. 初始化本机映射失败时，您会在设备上获得OSM作为后备。 Make sure you followed the integration instructions as explained here . 确保遵循此处说明的集成说明。

You can debug the issue on an Android device by connecting the device with a cable and launching the DDMS tool from the Android command line SDK. 您可以在Android设备上调试问题，方法是使用电缆连接设备并从Android命令行SDK启动DDMS工具。 In 90% of the cases this means your SHA1 is different from the one defined in the maps API and this will be printed when you try to open the map. 在90％的情况下，这意味着您的SHA1与maps API中定义的SHA1不同，并且在您尝试打开地图时会打印出来。

On the simulator OSM is shown unless you provided the Google maps provider in the constructor. 除非您在构造函数中提供了Google地图提供程序，否则在模拟器上将显示OSM。
