错误：程序类型已存在：android.support.v4.app.INotificationSideChannel$Stub

我已将Firebase数据库集成到我的Android应用程序中，并得到如下错误：

Error:Program type already present: android.support.v4.app.INotificationSideChannel$Stub

You can also check my build.gradle file as below : (Project Level)

buildscript {

        google()
        jcenter()
    }
    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()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
apply from: './build_version.gradle'

您可以按如下方式检查我的gradle文件：

    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
apply from: './build_version.gradle'

我还在AndroidManifest.xml文件中指定了所需的Internet权限：

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission. ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.INTERNET" />

可能有什么问题？

您正在使用需要androidx迁移的firebase库。你不能使用android支持库。这就是为什么像上面那样做：android.useAndroidX=true可能是不够的。在build.gradle中更改依赖项
