React-native: Error when react-native run-andoird on android device

[emclab]

I am following the doc below to test a simple react-native app on Android device.

https://facebook.github.io/react-native/docs/running-on-device

The Android phone is connected with Win 10 with USB cable and adb devices listed the phone attached. Then react-native run-android has the error below:

JS server already running.
Building and installing the app on the device (cd android && gradlew.bat installDebug)...

./gradlew.bat installDebug returns the command was not recognized and there is no templates subdir under my C:\Users\user\AppData\Local\Android\Sdk\tools (as one post suggests adding the path). Did I miss some debug modules with the proejct? Many thanks.
