Just asking

[MikaCybertron]

Does it works on Android Emulator such as LDPlayer and Nox??

[SsageParuders]

In my last tested for LDPlayer and Nox on Windows.

---

My Injecter had supprot for LDPlayer x86.
But it failed for LDPlayer x86_64.(Haven't be supproted,will do it in future)

---

In theory,my injecter must work fine on Nox x86, but I don't know why it was failed.
Also don't supprot for Nox x86_64 now.

---

I was busy those days. But I will update this Injecter in future, will support for x86_64.

---

Finally, if you want to inject a shared library on Android Emulator.
You must need to take care ,when process just have arm shared libraries , don't inject a x86 or x86_64 shared library to it.

ok

Hi! Hope you are doing well. Can you help me with hooking java api call in Android, from an injected Shared Library? It's easy for us to hook a native function after injection by using the function address/offset. But I have no clear idea how to hook java api calls. For simplicity, I just want to hook the basic Android api calls made from java such as the method "getString()" under the class "Settings$Secure". I will be looking forward to hearing from you.

Bro, we can't hook a Java API by inject a native shared library.

Maybe you need to learn some Java Hook frames like LSPosed

Failed to inject arm library in arm-only application in Emulator.

The inject framework work smoothly on Android device.
But when I try to inject a library in LD Player Emulator, it fails!
The target application was a 32-bit arm application & I tried injecting a 32-bit arm payload.

[+] libc_path is /system/lib/libc.so
[+] linker_path is /system/bin/linker
[+] libdl_path is /system/lib/libdl.so
[+] system libs is OK
[-] selinux_mnt is nullptr
[+] Start Inject
[+] lib_path is /data/local/libpayload.so
[+] handle_parameter is OK
[+] SELinux is Permissive or Disabled
[+] attach porcess success, pid:3185
[-] Get Regs error, pid:3185, err:Device or resource busy
[+] detach process success, pid:3185
[-] Inject Failed

So the problem is with
ptrace(PTRACE_GETREGS, pid, NULL, regs)

it is because most Emulator 32-bit is based on x86, so you should inject with abi x86 not armv7, but you can try with 64-bit Emulator
