      Description

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

      Example output:

      BUILD SUCCESSFUL
      
      Total time: 1.601 secs
      Built the following apk(s): 
      	/Users/Joanne/Desktop/learning/mobile/platforms/android/build/outputs/apk/android-debug.apk
      ANDROID_HOME=/Users/Joanne/Library/Android/sdk
      JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home
      No target specified and no devices found, deploying to emulator
      Error: Cannot read property 'replace' of undefined

      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.
