1. Asus Z010D (aarch 64)
2. Gionee G7a (aarch 64)
3. Oppo A37f (Lollipop - AArch64 - arm64-v8a instruction set)

I took pjsua build for architecture armeabi-v7a and arm64-v8a.

I came to know that these failed devices fall under AArch64 architecture. How can i take a build for AArch64? Why App crashes on these devices without showing any error logs?

Answer 1

After searching, I found out that the issue is with my ndk. I am using latest version of ndk which is r20. afaik, r20 does not support android versions below 7. So, I want to minimise my android NDK version to something 15 or below for my app to run on android devices below 7.
