我正在尝试制作一个与我的REST API通信的简单应用程序，因此我使用gson。 在尝试导入安全的args进行导航之前，这是可行的。 我想当我使用android studio中的工具迁移到androidx时，使问题变得更糟。 （The given artifact contains a string literal with a package reference 'android.support.v4.widget' that cannot be safely rewritten）

我现在收到此错误： https://pastebin.com/qNuSCY92

这是我的项目gradle：

buildscript {
    repositories {
        google()
        jcenter()   

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.2'

        def nav_version = "2.1.0"
        classpath "androidx.navigation:navigation-safe-args-gradle-plugin:$nav_version"
        // 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
}

这是我的应用程序gradle：

apply plugin: 'com.android.application'
apply plugin: "androidx.navigation.safeargs"

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.1"
    defaultConfig {
        applicationid "com.example.reconstruct"
        minSdkVersion 19
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'),'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs',include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.cardview:cardview:1.0.0'

    implementation 'com.squareup.retrofit2:retrofit:2.6.2'

    def nav_version = "2.1.0"
    implementation "androidx.navigation:navigation-safe-args-gradle-plugin:$nav_version"

    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.2.0'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'

    def lifecycle_version = "2.1.0"
    annotationProcessor "androidx.lifecycle:lifecycle-compiler:$lifecycle_version"
    implementation "androidx.lifecycle:lifecycle-extensions:$lifecycle_version"

    implementation "androidx.room:room-runtime:2.2.1"
    annotationProcessor "androidx.room:room-compiler:2.2.1"
    implementation 'androidx.navigation:navigation-fragment:2.1.0'
    implementation 'androidx.navigation:navigation-ui:2.1.0'

}

我认为问题在于版本兼容性，但是我不知道从哪里开始寻找。

感谢您的帮助。
