所以我尝试在我的应用程序中实现一个 map fragment 。该应用程序在我的 Galaxy S4 上运行良好，但无法在我的 Xperia Z 上运行。 fragment 显示为空白，没有 map 。 LogCat 指出:
07-31 00:20:07.265: E/Google Maps Android API(8763): Failed to load map. Error contacting
Google servers. This is probably an authentication issue (but could be due to network errors).
所以我检查了 Google-play-services_lib 的引用是否正确，我确实这么认为。所有权限都可以，一切都应该正常工作。 (我假设身份验证问题是伪造的，因为它在 S4 上工作？)。
然后我在没有过滤器的情况下检查了 logcat，我收到了一堆毫无意义的文本:

它就这样一直持续下去。我无法理解它。如果我删除与 map 相关的所有内容，错误就会停止。所以它与触发错误的谷歌地图有关。以下是包含 Gmaps 代码的类:

我知道可怕的编码，现在非常困惑。对不起!
最佳答案
Note: You cannot inflate a layout into a fragment when that layout includes a fragment. Nested fragments are only supported when added to a fragment dynamically.
此外，在玩嵌套 fragment 时，请使用 getChildFragmentManager()。
在你的情况下，它可能在 Galaxy S4 上工作(但它不应该，但你很幸运)，但在 Xperia Z 上不起作用。
