【问题描述】：

我在 Mac 上使用 React Native CLI 创建了一个入门应用程序，添加了 Detox 并尝试运行示例测试。我收到此错误（为便于阅读添加了换行符）：

$ ./node_modules/.bin/detox -c android test
detox[37289] INFO:  [test.js] configuration="android" reportSpecs=true readOnlyEmu=false 
    useCustomLogger=true forceAdbInstall=false DETOX_START_TIMESTAMP=1591313397594 
    node_modules/.bin/jest --config e2e/config.json '--testNamePattern=^((?!:ios:).)*$' -- 
    maxWorkers 1 android test
detox[37290] INFO:  [DetoxServer.js] server listening on localhost:62332...
detox[37290] ERROR: [DetoxExportWrapper.js/DETOX_INIT_ERROR] 
 DetoxRuntimeError: Failed to run application on the device

HINT: Most likely, your tests have timed out and called detox.cleanup() while it was 
waiting for "ready" message (over WebSocket) from the instrumentation process.

当它运行时，模拟器会启动，但应用程序不会。

应用通过 React Native CLI 独立于 E2E 测试运行良好。

.detoxrc.json

  "testRunner": "jest",
  "runnerConfig": "e2e/config.json",
  "configurations": 
    "android": 
      "type": "android.emulator",
      "binaryPath": "android/app/build/outputs/apk/debug/app-debug.apk",
      "build": "cd android; ./gradlew assembleDebug assembleAndroidTest -DtestBiuldType=debug; cd -",
      "device": 
        "avdName": "Pixel_3"
      
    
  

环境：

Detox: 16.7.0
React Native: 0.62.2
Node: v12.17.0
Device: Pixel 3, x86, API 29, Android 10
OS: MacOS 10.15.4
Test-runner: Jest
Android Studio: 3.6.3

我的错。我错过了特定于 Android 的入门说明第二页上的几个步骤。
