Answer 1

错误在这里:

The meta-data tag in your app's AndroidManifest.xml does not have the right value. Expected 4323000 but found 0. You must have the following declaration within the element

将此 xml 添加到您的 list 中:

<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
