react-native build only (android)

Scenario

I used react-native run-android to build my android project but it also runs the project. Because I'm using an npm plugin to modify my build information I'm only interested in building rather than launching.

Question

With react native is it possible to build android files without launching? Theoretically something like react-native build-android or react-native run-android --build-only

Extra Info

I looked into the help for react-native run-android but didn't see anything promising.

$ react-native run-android --help
Scanning folders for symlinks in /Users/Jackson/Sites/fnmultiapptest/node_modules (11ms)

  react-native run-android [options]
  builds your app and starts it on a connected Android emulator or device

  Options:

    --install-debug           
    --root [string]           Override the root directory for the android build (which contains the android directory) (default: "")

    --deviceId [string]       builds your app and starts it on a specific device/simulator with the given device id (listed by running "adb devices" on the command line).

Navigate to the android directory and run ./gradlew assembleDebug. You can then manually install.

Maybe just with: 

cd android && ./gradlew build -x lint

(use gradlew.bat if you run it on windows)
