我知道它可能看起来像这个问题,但我无法用提出的解决方案解决它,我也无法评论它.错误是:

Program type already present: 
android.support.v4.app.INotificationSideChannel$Stub$Proxy
Message{kind=ERROR, text=Program type already present: 
android.support.v4.app.INotificationSideChannel$Stub$Proxy, sources=[Unknown 
source file], tool name=Optional.of(D8)}

我正在尝试使用firebase创建一个应用程序,这是我的gradle文件

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
    minSdkVersion 27
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
aaptOptions {
    noCompress "tflite"
}
}
