我正在Android上测试谷歌地图v2。我跟着这个

当我在手机上运行应用程序时，我看不到地图。我不知道为什么。我不认为我忘了什么。我已经配置了所有必要的东西

这是一个截图：

有人能帮我吗？

<permission

android:protectionLevel="signature"></permission>

<uses-permission android:name="your_package_name.permission.MAPS_RECEIVE"/>

这些需要匹配，在您的情况下，您需要将使用权限更改为

<uses-permission android:name="com.example.googlelocatorv2.permission.MAPS_RECEIVE"/>

logcat上没有显示任何内容，您是否在设备上发现任何异常？问题的分步指南：双重检查使用权限和API密钥。如果可以的话，请发邮件代码。大家好，谢谢你们的帖子和帮助我的意愿。@拉梅什：你的链接是地图v1的。它适用于MapV1，但我现在正在使用MapV2。那有点different@gustek：我检查了我的使用权限和api密钥。我会把这封信寄出去code@user1953173：我也实现了站点代码，但我仍然在GoogleMap myMap=myMap.setMapType（GoogleMap.MAP\U TYPE\U HYBRID）上获得java.lang.NullPointerException；哦，玛恩，你说得对。我没有看到：（我更改了它，但结果仍然是一样的。最后一个选项是创建一个新的api密钥并立即运行。puh..它花了很多时间。谢谢gustek。你帮了我很大的忙；）

<uses-permission android:name="com.example.googlelocatorv2.permission.MAPS_RECEIVE"/>
