推荐答案
您确定您的API密钥是正确的?当API密钥不匹配,它显示了格,而不是地图。
Are you sure your API key is correct? When the API key doesn't match, it shows the grid instead of the map.
直接运行在仿真器上从Eclipse的应用程序/实际手机需要不同的键,然后当你第一次生成的.apk文件,并运行在设备上。
Running the app from Eclipse directly on the emulator / an actual phone requires a different key then when you build the .apk file first and run that on a device.
