[Android] "Build Failed" with no error; cannot run in Android emulator at all

Using:

• React Native v0.31.0
• react-native-cli v1.0.0
• Mac OSX El Capitan (10.11.6)
• Android Studio v2.1.3
• Android SDK API v23 (Marshmallow)

I’m trying to run the sample project https://github.com/mlaval/angular2-react-native-seed but as far as I can tell the issue is in the underlying react-native setup.

Building the iOS project & running the project in the xCode Simulator works like a charm; no problems whatsoever.

However, when attempting to build & run the Android project, I get:

Starting JS server...

Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

The “read the error above for details” is frustrating because there’s no error details being output anywhere. 😦

The separate React Packager window has:

Again, no obvious errors here, so at this point I have no clues as to what’s wrong with my setup and cannot get this working in Android at all, which is annoying.
