Android Firebase身份验证错误：我启用了电子邮件/密码选项

我正在尝试使用Android登录Firebase，我收到了奇怪的消息：

出现以下错误消息：

W/BiChannelGoogleApi:[FirebaseAuth:]GetGoogleAPI方法（） 返回的Gms D/ViewRootImpl:应用程序信息中的缓冲区计数为：：-1&&-1 com.butt.mediacalradar从视图：：-1 DBQ已启用：：false

更新后

---

为了使其正常工作，请对所有依赖项使用最新版本：

首先将google服务版本（build.gradle项目）更改为：

以及来自以下方面的依赖项：

compile 'com.google.firebase:firebase-database:11.8.0'
implementation 'com.google.android.gms:play-services-maps:11.8.0'
implementation 'com.google.firebase:firebase-database:11.8.0'
compile 'com.google.firebase:firebase-auth:11.8.0'
implementation 'com.google.android.gms:play-services-ads:11.8.0'

到

如您所见，第一行已注释。不要忘记删除重复的

应用插件：“com.google.gms.google服务”

。应该只保留在文件的末尾。

您可以发布产生这些异常的Java代码吗？我们无法在不查看代码的情况下帮助您。您可以编辑自己的问题，然后在那里添加Java代码。请添加相应的代码。@AlexMamo code addedy您的代码看起来不错。还请添加您的

build.gradle

文件。@AlexMamo还在这两个库中添加了build.gradlegetting错误>编译'com.google.firebase:firebase数据库：11.8.0'和实现'com.android.support:appcompat-v7:27.0.1'，正如我所说的

编译'com.google.firebase:firebase数据库：11.8.0'

。第二个的错误是什么？我们很接近。我错误地将classpatch放到了app module gradel，但现在错误已经纠正。我是否应该将classpath'com.android.tools.build:gradle:3.0.1'更改为'com.android.tools.build:gradle:4.0.1'您应该使用最新版本。它现在可以工作了吗？它说所有的gms/firebase库必须使用完全相同的版本规范
