Answer 1

Java.lang.RuntimeException: API key not found. Check that is in the element of AndroidManifest.xml at ....

清单中似乎缺少必需的值（API密钥）。

Answer 2

Api键未在清单文件中定义。请在清单文件中输入必需的值，例如Api键。

Answer 3

您在应用中使用google maps API。 https://developers.google.com/maps/documentation/android-sdk/signup

您必须在manifest.xml中添加API密钥

<meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="YOUR_API_KEY"/>

检查链接，您会发现解决方案非常简单！

不幸的是，该应用已在android studio中停止
