直到昨天我的应用程序工作正常，今天突然它开始崩溃与Retrofit2错误所以我解决它通过升级依赖项并添加multidex到我的应用程序，问题是，现在当我尝试启动应用程序时没有找到任何类似它不存在的活动类，我在这里回顾了每个类似的问题，没有答案解决了我的问题，我不知道现在如何解决它，任何想法？，我使用自定义应用程序类：
MainApplication（科特林）：
class MainApplication : Application() {
override fun attachBaseContext(base: Context?) {
super.attachBaseContext(base)
MultiDex.install(this)
}
override fun onCreate() {
super.onCreate()
MainApplication.appContext = applicationContext
}
companion object {
var appContext: Context? = null
private set
}
}

答案 0 :(得分：0)
在Android Studio上禁用即时运行对我来说很有效。 （设置-生成，执行，部署>即时运行）
