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/.

【问题讨论】：
你能发布你的清单吗？ 绝对布局很久以前就被弃用了。你为什么还在用它？ 因为我想@VivekMishra 【参考方案1】：你应该使用片段class="com.google.android.gms.maps.SupportMapFragment"...而不是android:name="com.google.android.gms.maps.SupportMapFragment"
【讨论】：
【参考方案2】：添加 OnResume 方法并在那里初始化和设置 Map
【讨论】：
【参考方案3】：将此添加到您的清单中：
<meta-data android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
【讨论】：
你也可以发build.gradle吗？以上是关于在活动映射 xml 中膨胀类片段时出错的主要内容，如果未能解决你的问题，请参考以下文章
