Debug Log on the Emulator or Android Phone:
adb logcat
Struggled to get the emulator up and running using 'phonegap run android'. Eventually got it up and running on the Android Studio, which I couldn't do before. I'm now trying to use React to create a div on the front page. It's currently not appearing.
I found out about 'adb logcat'. I added a content-security thingy meta tag to the index.html due to warnings found in the adb logcat. I installed babel to precompile JSX. In moving my JSX code to its own file, JSHint let me know about a syntax error with my React.createClass call (I shouldn't have added a 'function()' inside. So Now I get the Red DIV! Yay!
