HELP
I was finished my very first app. in some device it work as well as i wan. I tested it to myfriend smartphones and then i found that in somebrand devices like transin group (infinx, tecn*, itel), and xiaom group (poc*, xiaom*, and redm*) the app is cant opened. It just can install, and then force closed when i try to open. Can someone tell me what happened to my very first app 
if you are using extensions some of them cant work on some android versions try changing extensions and also change minimum android version in project properites and also some permissions some phones doesn’t accept it and close the app thats all i know if you found that useful please press solution button
honestly, i dont use any extension
Use logcat to find out what happens on those devices

Check you min sdk level and try to keep lower
Do you see any king of error or its just black
also try checking minimum sdk level or blocks if there is a component causing it to crash !
there is no error message. when i click it, the app is just open and then get force closed soon. about minimum sdk, i used the lowest requirement. if the problem from the block, it shouldn’t be open in all devices. but in my case, the device from samsung, opp, viv*, iqo*, realm* can run the app normally
can you provide a apk here ?
sure, can u help to check my app
