标签： java firebase-authentication build.gradle

我使用firebase创建了一个使用google，facebook和电子邮件应用登录的应用。但是，当我测试它时，它会来＃34;不幸的是，这个应用程序已经停止工作了。＆＃34;。它在启动期间甚至没有启动，只会出现弹出窗口。我实际上在logcat中遇到了一些错误但我不知道如何解决它所以最终在这里获得帮助。 造成这种情况的错误就是我认为Didn't find class "com.google.firebase.provider.FirebaseInitProvider"

我尝试了所有的多指标，但没有任何效果。

请帮助我！

在项目级别Gradle中包含此内容

allprojects {
    repositories {
        jcenter()
        mavenLocal()
        maven { url 'https://maven.fabric.io/public' }
    }
}

您需要在应用级别Gradle

中使用此功能 
compile 'com.firebaseui:firebase-ui-auth:1.2.0'
