该问题不会发生在其他手机或模拟器上。

如果我使用命令行分别安装和启动应用程序，该应用程序运行良好：
./gradlew clean installMyApp && adb shell "am start -n com.abc.xyz/com.abc.xyz.activities.landing.splash.SplashScreen

在同一天，班级名称似乎是一致的。但是，当我隔几天再试时，这是一个不同的班级“失踪”

请注意，我不时看到许多不同且不相关的类“丢失”。这只是一个例子，不应该与问题本身有任何关系：（
使用 Dagger 2 进行依赖注入）

@ParametersAreNonnullByDefault
@Module(includes = NetModule.class)
class AppModule {

    //...

    @AppComponent.AppScope
    @Provides
    static Scheduler provideLooperScheduler() {
        // Please be sure not to execute long run executions with this scheduler
        // This scheduler is meant to be beneficial in timer/interval/retry/timeout/sample/window these rx.Operators
        final HandlerThread handlerThread = new HandlerThread("RxLooperHandler");
        handlerThread.start();
        return AndroidSchedulers.from(handlerThread.getLooper());
    }

    //...    
}
