解决方法

• 添加 multidex 库

implementation 'androidx.multidex:multidex:2.0.1'

• 配置 app/build.gradle

android {
    compileSdkVersion rootProject.ext.compileSdkVersion

    defaultConfig {
        // ...
        multiDexEnabled true
    }
}

• 在 MainApplication 中添加如下代码

  override fun attachBaseContext(base: Context?) {
    super.attachBaseContext(base)
    MultiDex.install(this)
  }
