Grepping for Glory : using grep to uncover Android Application Level Vulns

I've spent some time trawling through masses of Android App Sauce lately and I thought I'd share some quick tips and tricks that can help you uncover some critical vulnerabilities. In this post I'll discuss some basic bash scripting that pin points code being either in Java or Jasmin/Smali form.

A quick disclaimer, 

the screenshots below are from actual apps sourced from the play store, I've used real examples here to motivate the need to look for the mentioned vulnerabilities and detail how easy they are to find. Although I've made sure to santize them for any useable or exploitable information seeing that some of these apps have been downloaded hundreds of the thousands of times.
