我已将这些库添加到我的代码中
implementation 'com.google.firebase:firebase-core:16.0.1'
implementation 'com.google.firebase:firebase-database:16.0.1'
implementation 'com.google.firebase:firebase-auth:16.0.2'
然后我发现该行有错误
implementation 'com.android.support:appcompat-v7:27.0.2'
说存在混合版本问题

尝试添加所有相同版本的firebase api:
SelectedInventory
更改:
implementation 'com.google.firebase:firebase-auth:16.0.2'
也许应该有帮助。

您的Firebase依赖项已更新,因此如果您不这样做,则首先更新您的构建工具版本:
buildToolsVersion '27.0.3'
将27.0.2替换为:
implementation 'com.android.support:appcompat-v7:27.1.1'
(还要确保每个库都已更新)based on this link for the latest varsion
确保您的gradle文件类似于:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
//..
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.3'
classpath 'com.google.gms:google-services:4.0.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
//..
}
}
