Question

当我在Android Studio中按“播放”按钮时，我的应用程序会编译，但显示此错误

Program type already present: android.arch.lifecycle.LiveData$1

我尝试删除.gradle文件夹，然后转到Build > Clean Project和Build > Rebuilt Project。但是，它仍然会产生该错误。

这是我的应用的app/build.gradle：

apply plugin: 'com.android.application'
android {
compileSdkVersion 27
defaultConfig {
    applicationId "xxxxxxxx"
    minSdkVersion 19
    targetSdkVersion 27
    multiDexEnabled true
    versionCode 5
    versionName "1.0.4"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'),  'proguard-rules.pro'}
}
}dependencies {

implementation fileTree(include: ['*.jar'], dir: 'libs')

程序类型已存在：Android Studi 3.1.2中的android.arch.lifecycle.LiveData $ 1
