Using SoLoader crashes because phone complains the lib is 32-bit

[molikto]

Hello. We have a app only ships armabi-v7a binaries. And rely on other abi's legacy support. But we have this crash log:

So using lib-main only happens if System loader failed. This error happens on a Lenovo z90-7 phone

[michalgr]

Hi, thanks for reporting !

Are you able to reproduce this on your device ? Is it 100% reproducible on that phone ?

In theory, android should spawn your app off 32bit zygote if the app contains only armv7 libs. Here obviously it does not do so. Are you sure you have no armv8 libs in your apk ? You can double check by checking output of unzip -lv <path-to-your-apk> | grep 'lib/' If there is at least one 64bit library Android will refuse to run in compatibility mode.

The scary alternative is that android did not unpack any libs and it fails to recognize that your app requires compatibility mode. Let's worry about that after we rule out existance of armv8 libs.

I suspect this is the same issue (hard crash on app bootstrap, see stacktrace below) for Facebook, Messenger, Groups and Pages. By rolling back to com.facebook.katana_98.0.0.18.70-41212249_minAPI15(armeabi-v7a)(280,360,400,420,480,560,640dpi)_apkmirror.com.apk this is no longer an issue.

[molikto]

There is no way to reproduce it. This is a stack trace from online bug reporting. Our app has a big installation number, and this crash only happens very rarely.

[johnou]

I can reproduce it 100% I took this stacktrace from adb logcat, feel free to reach out to me if you'd like to resolve it.

[rspencer01]

This appears to be due to this line. https://github.com/facebook/SoLoader/blob/master/java/com/facebook/soloader/SysUtil.java#L125. I am looking into changing it.

[iegik]

It happens with x64 chips like KIRIN 950, KIRIN 955 and Exynos 7420:
https://it.wikipedia.org/wiki/HiSilicon#KIRIN_950
Huawei Mate 8, Honor 8, Honor V8 (KNT-AL10, KNT-TL10)
Huawei P9, Huawei P9 Plus, Honor V8 (KNT-AL20), Honor Note 8

https://ru.wikipedia.org/wiki/Exynos
Galaxy S6 Edge (zerolte),

Platform armeabi-v7a

[iegik]

Both is with 8 CPU

[rspencer01]

I did submit a patch when I was with facebook. @michalgr , will it be published?

[passy]

This is now in master with c3b57fa
