Andriod 4.4.2 "optimizing app x of 50 android" after flash Gapps I've flashed Gapps for kitkat in my andriod 4.4.2, and now when I turn on the phone, The problem is that always said "optimizing app x of 50 android", the which take much time. (I also happened to this with a cell phone jellybean after flash Gapps)

I've tried advance factory reset from TWRP but this not change, also reflash other Gapps..

Note: I dont wanna update kitkat to Lollipop because lollipop have so many bugs in my phone (Azumi A50+)

Help me please, thank you very much
I guess you have a stock firmware, this might lead to an incompatibility with the existing Gapps. 

Try downloading the minimal Gapps,  nano or pico package from here
