Description

Error happens when running `cordova run android` or `cordova emulate android`:

Example output:

A solution was also proposed here:

I just came across the same problem. I tracked it down to file /platforms/android/cordova/lib/emulator.js line 202:

var num = target.split('(API level ')[1].replace(')', '');

I replaced it with a regex search and extraction:

var num = target.match(/\d+/)[0];

Not sure if this is the right way to fix this.
