Android UnknownHostException 即使有一个活动的和工作的互联网连接

Question

我抛出了很多UnknownHostException并且应用程序完全与互联网断开连接，这个问题发生在多个应用程序中 我正在处理的问题主要发生在三星和小米设备上

当用户将应用程序长时间留在后台（例如 12 小时）并且用户仅在用户重新启动应用程序时才能访问互联网时，会发生此问题，我认为这些设备正在清除 memory 中的某些内容，它正在介绍这个问题。

我正在使用 Hilt 来提供依赖项，并将它们创建为 Singletons 这里是 dagger 模块：

@Module
@InstallIn(SingletonComponent::class)

    fun provideManexPressService(retrofit: Retrofit): ManexPressService =
        retrofit.create(ManexPressService::class.java)

    @Singleton
    @Provides
    fun provideGson(): Gson = Gson()

    @Provides   /* provide gson converter */
    fun provideConverterFactory(gson: Gson): Converter.Factory {
        return GsonConverterFactory.create(gson)
    }


    @Provides
    @Named("AuthInterceptor")
    fun provideAuthInterceptor(): Interceptor =
        Interceptor { chain ->
            val newBuilder = chain.request().newBuilder()
            if (chain.request().headers.none { it.first == "Authorization" }) {
                TokensManager.requestJwt?.let {
                    newBuilder.addHeader("Authorization", "Bearer $it")
                }
            }
            newBuilder.build().let { chain.proceed(it) }
        }

    @Provides
    fun providesNetLoggingInterceptor() = NetLoggingInterceptor()

    @Provides
    @Named("LoggingInterceptor")
    @Singleton
    fun httpLoggingInterceptor(): Interceptor {

            }.setLevel(HttpLoggingInterceptor.Level.BODY)
        else

    }

        addInterceptor(authInterceptor)
        addInterceptor(loggingInterceptor)
        addInterceptor(PlutoInterceptor())
        addInterceptor(netLoggingInterceptor)
        connectTimeout(2, TimeUnit.MINUTES)
        readTimeout(2, TimeUnit.MINUTES)
        build()
    }


    /* operation work of api using retrofit */
    @Singleton
    @Provides
    fun provideRetrofit(
        @ApplicationContext context: Context,
        okHttpClient: OkHttpClient,
        converterFactory: Converter.Factory
    ): Retrofit = Retrofit.Builder()
        .baseUrl(context.getString(R.string.base_url))
        .addConverterFactory(converterFactory)
        .client(okHttpClient)
        .build()
}

我进行了很多研究，但找不到任何有效的解决方案我已经实施了一种解决方法，它现在似乎正在工作我已将网络实施移至ActivityRetainedComponent ，如果它在后台停留超过 10 分钟，我将重新启动该活动。 我知道这不是最佳做法，但这是我目前唯一的选择，我愿意接受任何建议。
