I have faced architecture related issue in Android API level 25, Nexus 9, [ issue- map doesn't load, app just crashes].
I debugged and It can be solved by adding supported architecture in the gradle file but I am not sure should it be done or is there any other way through ESRI ?
Adding this works,
ndk {
abiFilters "armeabi", "armeabi-v7a", "x86", "mips"
}
Adding architectural related code sometimes gets rejected by google play store.
