[Q] Need help interpreting logs: compilation error - Android Q&A, Help & Troubleshooting

Hey there,
I recently started modding the stock 4.2.1 Gmail app to make it inverted with red accents and I'm running into errors when trying to compile. The only changes I've made were on /res/values/colors.xml (changing color hex values only, standard stuff). I'm using APK multitools, have my framework in proper dir, using option 12 (compile non-system APK)...
Running custom TouchWiz 4.1.1 ROM on Galaxy S3 T999
Here are the logs:

Press any key to continue . . .
Anybody knows what could be going on here? Thanks!
EDIT: for each of the problematic XML files, the attribute 'widgetCategory' has a value of 0x3...would that be normal?? Would I need a 4.2.1 framework to compile this 4.2.1 Gmail apk (don't think this would necessarily make sense...)?

Found problem to this issue!
Solution was to remove lines for attribute 'widgetCategory' for:
\res\xml\gmail_widget_info.xml
\res\xml-sw600dp\gmail_widget_info.xml
res\xml\widget_info.xml
\res\xml-sw600dp\widget_info.xml
Recompiled without any errors, couldn't find any impact on functionality!
