Install ARM Binary Translation on x86 AVD

[Xun H.W]

I am trying to run Apps with native arm libraries on x86 avd (which is faster than ARM Avd )

but failed:(

this is what I am doing:

1. create an avd with Intel atom x86 image, google api level 23
   
2. grab libhondini from Nexus Player factory image, (basically /system/lib/arm/* , /system/bin/houdini & /system/lib/libhoudini.so)
3. patch x86 AVD's system.img & ramdisk.img to enable native bridge(houdini)
4. then boot avd and run App with only arm native lib included (like firefox, Skype, Wechat etc).

Native bridge seems to works:

02-25 15:04:11.990 1512 1620 I ActivityManager: START u0 {act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10200000 cmp=com.tencent.mm/.ui.LauncherUI (has extras)} from uid 10007 on display 0

 But App still fail to run, when check demsg there is a general protection fault 。

[ 366.571014] traps: com.tencent.mm[2586] general protection ip:b0f13dd1 sp:10011f20 error:30 in libhoudini.so[b0cfa000+3b4000]

Does anybody know what happens here, Is it possible to make it works?

Thanks 

Best,

You are using y version of libhoudini
which is targeted for 64k32u.

Do you have a 64-bit kernel?
I guess not.

Hi Huang, thanks for reply. 

I thinks that's exactly the reason of my issue. 

But why targeted for 64k32u? do we have libhoudini  targeted for 64k64u or 32k32u?

I have. I don't know if you have or not.

Could you share it or where I can download myself? 

thanks!
