修改 build.gradle(:app)

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.0"

    defaultConfig {
        applicationId "com.xxx.test.dave"
        minSdkVersion 19
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"
        multiDexEnabled true <------这里

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
...
}

dependencies {
  ...
    implementation 'com.android.support:multidex:1.0.3' <---这里
  ...
}

Your Application must be of the Multidex type.. You must write it in the manifest :
android:name=".MyApplication" <---这里
"MyApplication" must be either the Multidex class, or it must extend it.
