Houdini native bridge - is it needed? Getting "Unable to find native library main"

[Akash Verma]

I have been able to run Dungeon Keeper and Don't Starve under Houdini; these games don't run without it. For them, I get messages like these in logcat:

06-01 00:57:47.154  8792  8816 D houdini : [8816] Added shared library /data/app/com.ea.game.dungeonkeeper_na-1/lib/arm/libAkSoundEngine_armeabi-v7a.so for ClassLoader by Native Bridge.

However, I get no such message for Hitman Sniper and Angry Birds 2. Angry Birds 2 launches fine (I guess it's an x86 binary?), but for Hitman Sniper:wWhether I enable the bridge or not, I get the following error message; I can't figure out if it needs Houdini, or is missing some other library. Thoughts on what I can try next?

Some apps have x86 native binaries, some don't. Those which only have binaries for ARM use Houdini.

Yes, this one seems to have x86 as well as ARM libraries. Thoughts on what can be done to run it?

That message "Unexpected CPU variant for X86" makes me think the application
has X86 binaries (and therefore doesn't need Houdini), but is getting
surprised at some detail of the CPU it's running on.

Exactly what CPU do you have in this machine?

Is there a way to make the game install and run the ARM version rather than the x86 version?

[Chih-Wei Huang]

To see which abi this app installed, check its lib dir like:

ls -l /data/app/com.squareenixmontreal.hitmansniperandroid-1/lib

If you see arm or arm64, it needs houdini.

Yes, some apps have x86 version but it's broken.
But its arm version could be run via houdini.
Such apps are common in PRC markets.

To install the arm version, it depends on how the apk is packed.
If the vendor ships separate x86 and arm apks (case 1),
just download the arm version (via an arm phone),
extract the apk and install it to android-x86.

If the vendor ships one apk containing both x86 and arm libs,
(case 2) it's more tricky to handle that.

To check which case it is, unzip the apk (an apk is just a zip file)
to see what libs it contains.
If it contains only x86 libs, it's case 1.
If it contains both x86 and arm libs, it's case 2.

For case 2, we have introduced so called "abipicker" feature
(made by Intel) since 7.1-r2. (only 7.1-r2 or later has this feature)
It will auto detect whether if the x86 libs are broken and
just install the arm version.
However, in case the auto detection not work,
you can manually add the package name to
/system/vendor/etc/misc/.OEMBlackList
to force it installed the arm version.

To check whether if it works, use pm dump to check
which abi is installed exactly:

pm dump com.squareenixmontreal.hitmansniperandroid | grep Abi
