Question

我有一个Android Instrumented测试，我尝试启动我的应用程序并执行以下操作：

open class MyApplication : Application() {

...

  override fun onCreate() {
    super.onCreate()

    initialiseLogging()
    initialiseStrictMode()
    initialiseDependencyGraph()
  }

  private fun initialiseDependencyGraph() {
    applicationComponent = createApplicationComponent()
    applicationComponent.inject(this)
  }

...

  private fun initialiseStrictMode() {
    StrictMode.setThreadPolicy(StrictMode.ThreadPolicy.Builder()
      .detectDiskReads()
      .detectDiskWrites()
      .detectNetwork()
      .penaltyDeath()
      .build())
  }
}

当我在Firebase上运行时，

所有测试都会在大多数设备上传递，但带有Nougat的华为Mate 9（带有API 24的Android 7.0）除外。当我对这个设备运行我的测试时，我收到以下错误：

我很清楚，StricMode发现了一个奇怪的错误，ActivityThread尝试通过使用主线程从磁盘加载字体系统来初始化字体系统。

网上没有提供此漏洞的解决方案，我的测试仅针对此特定设备失败，这似乎很奇怪。

任何人对如何解决此问题或可能导致此问题的想法有任何想法？
