💬 Description

I use my phone to run app. when install is done, app icon is just black and when i touch to run screen change to lock screen. after I unlock the screen success to run app. so screen transfer to lock screen when i touch or hover the app icon and i find out in stack overflow someone's comment to how to fix it. It is delete a file in \android\app\src\main\res\mipmap-anydpi-v26. after that it is working properly. I think it makes null error
