Google Play登录不断失败异常:4 [英] Google Play Sign in keeps failing Exception: 4

问题描述

因此，我一直在尝试很长一段时间，以使我的应用获得Google玩游戏的成就，但我无法使其正常运行.我一直在遵循此指南: https://developers.google. com/games/services/android/signin#implementing_player_sign-in 并没有成功，每次我打开我的应用程序时，它都会启动登录过程，但随后会停止并显示失败.这可能是我想念的，但是我仍然无法弄清楚.

So I've been trying for a long time now to get my app the have google play games achievements and I can't get it to work. I've been following this guide: https://developers.google.com/games/services/android/signin#implementing_player_sign-in and am having no success, every time I open my app it starts the sign in process but then it stops and says it's failed. It's probably something I missed, but I still can't figure it out.

输入一些代码的时间:

build.gradle:

build.gradle:

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.google.code.gson:gson:2.8.0'
    implementation "com.google.android.gms:play-services-games:12.0.1"
    implementation "com.google.android.gms:play-services:12.0.1"
    implementation 'com.android.support:multidex:1.0.3'
}
