So I made a really simple game running at 240x160 resolution with almost nothing in it just so I could go trough all the app making steps, but the app lags really badly on my phone and then an error pops "unfortunately app has stopped working"
I have installed jdk 8 , android sdk (api 25). My phone runs android 5.0
I tried changing api to 21 , and target build for 5.0 and lowest possible (2.0). Different fit to screen settings but it didn't change anything.
What do you think? Could I have missed some setting. I searched a lot of old posts checked everything many times.
