After I updated my project to AndroidX with targetSdkVersion set to 28, my project crashes on installing it from the store for beta testing.
AndroidX
targetSdkVersion
In my case, I manually moved everything in res/drawable-v24 to res/drawable folder and res/mipmap-anydpi-v26 to res/mipmap-hdpi and problem was solved in phones with Android 5 and 6.
res/drawable-v24
res/drawable
res/mipmap-anydpi-v26
res/mipmap-hdpi
