Is this a bug report?

Not sure,

Have you read the Contributing Guidelines?

yes, I already read it.

Environment

Environment:
  OS:  macOS High Sierra 10.13
  Node:  7.9.0
  Yarn:  0.23.3
  npm:  4.2.0
  Watchman:  4.9.0
  Xcode:  Xcode 9.0 Build version 9A235
  Android Studio:  2.3 AI-162.4069837

Packages: (wanted => installed)
  react: 16.0.0-beta.5 => 16.0.0-beta.5
  react-native: 0.49.3 => 0.49.3

  Target Platform: iOS (10.3)

Steps to Reproduce

No steps, needed.

Expected Behavior

when I run this code

react-native bundle --dev false --platform android --entry-file index.js --bundle-output ./android/app/build/intermediates/assets/debug/index.android.bundle --assets-dest ./android/app/src/main/res/ --assets-dest ./android/app/build/intermediates/res/merged/debug
....
cd android/
./gradlew assembleDebug

I should expect a working APK file which I can install on other devices that will run same when I do run this command react-native run-android

Actual Behavior

I got this error when I tried to install it on other devices using the APK, if I connect it with my laptop and it has debugging host, it works fine. Yesterday this process works fine but now this errors keep showing. On my other projects this process seems to be working fine when installing it via generated APK files.

thanks,
