Java Can';t在我的android应用程序上实现firebase依赖项
我正在开发一个Android Studio应用程序,并试图创建一个用户注册活动。我已经将firebase添加到项目中,但是当我尝试添加firebase数据库依赖项时,应用程序会立即崩溃,并且不会报告任何错误。但是,当我从构建梯度中删除3个实现时,它会正确运行。这里我留下两个构建梯度代码。谢谢 构建梯度项目:Java Can';t在我的android应用程序上实现firebase依赖项,java,android,database,firebase,dependencies,Java,Android,Database,Firebase,Dependencies,我正在开发一个Android Studio应用程序,并试图创建一个用户注册活动。我已经将firebase添加到项目中,但是当我尝试添加firebase数据库依赖项时,应用程序会立即崩溃,并且不会报告任何错误。但是,当我从构建梯度中删除3个实现时,它会正确运行。这里我留下两个构建梯度代码。谢谢 构建梯度项目: // Top-level build file where you can add configuration options common to all sub-projects/modu

已解决
问题是我运行的是一个旧的Android Studio版本。我更新了Android Studio并检查了gradle版本,现在一切正常,谢谢。当您使用firebase bom依赖项时,无需提及firebase数据库和其他firebase库的版本 firebase bom将为您选择正确的版本,或者如果您想要特定版本的firebase,请删除firebase-bom。因此,添加如下所示的依赖项
// Import the BoM for the Firebase platform
implementation platform('com.google.firebase:firebase-bom:28.0.1')
// When using the BoM, you don't specify versions in Firebase library dependencies
implementation 'com.google.firebase:firebase-auth'
implementation 'com.google.firebase:firebase-core'
implementation 'com.google.firebase:firebase-database'
