转成android studio工程, 并且让它支持x86 about dexposed

[hwjump]

Nice！If we can debug so in studio， it will be more effective！
So what problem on art？

[pangliang]

art 模块中那个 art_quick_dexposed_invoke_handler.S 汇编, 我放到jni目录里android studio好像并不会编译, 因为ld会报错无法找到函数, 不知道是不是我使用了太新版的gradle-experimental:0.2.0

我现在的临时解决办法是把你之前的art_quick_dexposed_invoke_handler.o文件改成.so 放到 jniLibs中让他去link
现在的状态是编译成功, 但是放到我的mezumx3 android 5.0 中报错, 我明天再看看

然后, art_quick_dexposed_invoke_handler.S这个东西是arm-v7a的汇编吧? 那得另外搞一份x86的汇编来支持才行了...

另外,因为dalvik 和art同时存在同时要include源码的关系, 整个android 源码目录, plaform/art 这个project 得是 android-5 , 其他的可以保持在 android-4

暂时遇到的就是这些问题

I didn't compile .S file in studio, So I can't give any suggest. But I found some information for you https://code.google.com/p/android/issues/detail?id=15379. I think ndk-build support .S file, so also studio can support.

As question2: Yes, art_quick_dexposed_invoke_handler.S is for arm 32 bits. So X86's .S file, you should find it in /runtime/arch/x86 directory in art android AOSP, and do some change.

Thank you for your work！

hello, art 的x86 和 armeabi 都已经编译成功, 但是放到手机上运行, 报错之后退出了:

08-18 16:33:41.565  28651-28651/com.taobao.dexposed A/art﹕ /Volumes/d/dexposed/dexposed_art/src/main/jni/dexposed.cpp:201] Check failed: proxy_method->GetFrameSizeInBytes() == Runtime::Current()->GetCalleeSaveMethod(Runtime::kRefsAndArgs)->GetFrameSizeInBytes() (proxy_method->GetFrameSizeInBytes()=3179300541, Runtime::Current()->GetCalleeSaveMethod(Runtime::kRefsAndArgs)->GetFrameSizeInBytes()=48) void com.taobao.dexposed.MainActivity.test()

使用你原版的lib 来运行, 也只是显示如下log, 并没有调用设置的beforeHookedMethod
也没有任何报错

不知道是art 本来就没有实现, 还是别的什么原因 ?

[hwjump]

hey， I read your code， the “void com.taobao.dexposed.MainActivity.test()” shouldn't empty. there should be have some code. Because art compiler optimization.

As this jni compiled so run error, I think the reason was the compile environment， the artmethod framesize wasn't same.

[hwjump]

I have another suggest. I think this modify will be better if it didn't dependecy Android AOSP.
You can see this project ( https://github.com/boyliang/AllHookInOne ), he remove the Android AOSP dependecy with (https://github.com/boyliang/ndk-patch) which copy any necessary so into it's ndk directory.
