Android View InflateException错误
所以，android.view.InflateException我遇到了很多麻烦，我不能完全确定原因。当我尝试加载Google Maps Fragment时会发生这种情况。
非常感谢任何有关此错误的想法/帮助。

<!--
The API key for Google Maps-based APIs is defined as a string resource.
(See the file "res/values/google_maps_api.xml").
Note that the API key is linked to the encryption key used to sign the APK.
You need a different API key for each encryption key, including the release key that is used to
sign the APK for publishing.
You can define the keys for the debug and release targets in src/debug/ and src/release/.

您的api密钥设置不正确，您可以在日志中看到：
Caused by: java.lang.RuntimeException: API key not found. Check that <meta-data android:name="com.google.android.geo.API_KEY" android:value="your API key"/> is in the <application> element of AndroidManifest.xml
首先，更改清单中API密钥引用的新格式。
改变这个：
<meta-data
android:name="com.google.android.maps.V2.API_KEY"
android:value="@string/google_maps_key" />
对此：
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="@string/google_maps_key" />
请注意，如果您还没有这样做，则需要使用keytool来获取调试密钥库和发布密钥库的SHA1指纹，并在Developer Console上设置API密钥
有关从调试/发布密钥库中获取SHA1指纹的信息，see here。
您将在开发者控制台的API密钥中使用这些SHA1指纹：
设置好API密钥后，将其放入"@string/google_maps_key"，即可完成设置。
