[CodeCracker]

This is more like Android reversing...

Android boolean examples:
A boolean method changed to return false:
1200 const/4 v0 0
0F00 return v0

A boolean method changed to return true:
1210 const/4 v0 1
0F00 return v0

In your example niculaita:
move-result v1
; this set v1 with 1/0

ifnez v1, : cond1
; check v1
