【问题描述】：

每当我调用此代码时，我的应用程序就会崩溃：

if (FirebaseAuth.getInstance().getCurrentUser() == null) {
        startActivityForResult(
                AuthUI.getInstance()
                        .createSignInIntentBuilder()
                        .setAvailableProviders(providers)
                        .setLogo(R.drawable.shape_circle)
                        .build(), RC_SIGN_IN);
    }

奇怪的是这段代码一直工作到今天，我在这里没有改变任何东西，也没有改变任何依赖关系。但就在今天，它因以下异常而崩溃：

这些是我的 Firebase 依赖项：

compile 'com.google.firebase:firebase-core:16.0.0'
implementation 'com.google.firebase:firebase-database:16.0.1'
implementation 'com.google.firebase:firebase-storage:16.0.1'
implementation 'com.google.firebase:firebase-auth:16.0.1'
implementation 'com.google.firebase:firebase-firestore:17.0.1'
implementation 'com.google.firebase:firebase-crash:16.0.0'
implementation 'com.google.firebase:firebase-perf:16.0.0'
compile 'com.firebaseui:firebase-ui-auth:3.3.0'
implementation 'com.crashlytics.sdk.android:crashlytics:2.9.1'

任何想法可能是错的？

【解决方案1】：

我有同样的问题，在尝试了很多东西之后，这为我解决了这个问题：

我在 allProjects{} 上修改了我的 build.gradle 并添加了以下内容

allprojects {
  repositories {
    google()
    jcenter()
   //start here
    configurations.all {
        resolutionStrategy.eachDependency { DependencyResolveDetails details ->
            def requested = details.requested
            if (requested.group == 'com.google.android.gms') {
                details.useVersion '12.0.1'
            }
            if (requested.group == 'com.google.firebase') {
                details.useVersion '12.0.1'
            }
        }
    }
    //end
  }
}

对我的情况没有任何影响：我有一个类似的问题：stackoverflow.com/questions/60461110

【解决方案2】：

改变这个：

compile 'com.firebaseui:firebase-ui-auth:3.3.0'

进入这个：

compile 'com.firebaseui:firebase-ui-auth:4.0.0'

来自文档：

从 4.0.0 版开始，FirebaseUI 具有以下依赖版本：

Library Version
firebase-auth   16.0.1
play-services-auth  15.0.1
firebase-database   16.0.1
firebase-firestore  17.0.1
firebase-storage    16.0.1

【讨论】：

不，更新到 4.0.0 并不能解决这个问题。
在顶级 gradle 文件中使用它：classpath 'com.google.gms:google-services:4.0.1'
非常感谢，升级到 4.0.0 并更新了类路径。
