ARM application crashed after enable houdini

[zen...@163.com]

Recently, I have use the experience of some blogger that they can set up 'ARM to x86 translation by houdini' environment in some versions but some not. Thus I have installed a new image 'Android-x86-7.1-rc2' on VirtualBox and set up the environment again. By establish adb connect between my computer with emulator, I pull the '/system/bin/enable_nativebridge' script file to my computer to easy edit this script file. By observing this script file running in the emulator and looking at the file itself, I have noted that there's some URLs in the script file and URLs are short URLs. These URLs is used for download ARM to x86 translation image: 'houdini.sys'. After download 'houdini.sys', the script will install some kernel module including 'libhoudini.so'. Because of thess short URLs are not accessible in our region, so I used some short URL to real long URL translation tool to get the real download URL. And I using these real download URLs to replace those old short URLs. What's more, for I can easier to see the execute situation in emulator's terminal, I replaced some log statement to echo statement in script file. After changing the 'enable_nativebridge' file, I use adb to push this file back to emulator and start to run it. When the script file finished, 'houdini enabled' shows in the emulator's terminal. Then I open the 'enable running ARM application translation' option in 'system setting - Android x86 option'. Finally, we can run ARM application successful. However, the same method seems work in Android 8.1, but the actual situation is always crash. And we can see segment fault by observing log information.

Short Summary about Problems

1.Android-x86-7.1-rc2     houdini runs successful and application runs very well

2.Android-x86-8.1-rc1&2    houdini seems run successful but application always crashed when it opened

Could you please tell me how to solve this problem?

Is there any problem of my operation? Or it is the problem of houdini?

seem you use 32bit 8.1, the 8_y houdini not work on 32bit kernel 32bit userspace, but 8_y houdini work on 64bit kernel 32bit userspace.

32bit 8.1 default enabled 64bit binder, you can easily change 32K32u to 64K32U.

copy 64bit 8.1 /system/lib/modules/4.18 modules to 32bit 8.1, copy 64bit 8.1 kernel to 32bit 8.1, yes, 64bit kernel and modules can boot 32bit 8.1 userspace.

you can email me to discuss, you use 163 email speak chinese.
