I have an android tab (sony tablet s) on 4.0.1,and there are two things that i really need help with. i have tried googling all i could for both of them. first- there is a problem parsing the package. i have tried enabling installation of apks from unknown sources,but i still get that error on almost all the apks that i download. one worked when i transferred it from my computer but the others still wont work. and this is happening with many apks,not just one. second- i want to root my tab,with SUPERSU/SUPER USER i can root with kingoroot or kingroot or something but i want super user and not that chinese build. any help? thanks in advance!
