錯誤：無法解析：android.support:support.v7:29.0.2

Question

我是 Android 工作室的新手。 我正面臨編碼部分的問題。 運行代碼時顯示錯誤。 Thw gradle 部分如下所示

apply plugin: 'com.android.application'
android {
    compileSdkVersion 29
    buildToolsVersion "29.0.2"
    defaultConfig {
        applicationId "com.example.fallprediction"
        minSdkVersion 14
        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.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.13'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    implementation 'android.support:support.v7:29.0.2'
}

錯誤是 ERROR: Failed to resolve: android.support:support.v7:29.0.2 Show in Project Structure dialog Affected Modules: app

將其轉換為 androidx 或刪除此依賴項實現 'android.support:support.v7:29.0.2
