Android list :

....
 <meta-data android:name="com.google.android.gms.appstate.APP_ID" android:value="xxxxxxxxxxxxx" />

Answer 1

您正在使用 com.google.android.gms.appstate.APP_ID ，当错误提示您需要 com.google.android.gms.games.APP_ID 时.

此外:确保将元数据标记放在 <application> 中 list 中的标记。

最后，您应该使用 android:value 的字符串文件夹中的应用程序 ID。属性。最后它应该是这样的:

<application>
    ...
    <meta-data android:name="com.google.android.gms.games.APP_ID" android:value="@string/app_id" />
    ....
</application>

希望对您有所帮助!
