GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface 're.frida.HostSession' on object at path /re/frida/HostSession

After successful compilation, I try to find and run frida-ps (android server already launched and ports are forwarded) according this manual http://www.frida.re/docs/android/

And get this (I've checked permissions twice :) :

afx237@bright ~/frida> find | grep frida-ps
./frida-python/src/frida-ps.in
./build/tmp-linux-x86_64/frida-python3.4/src/frida-ps
./build/tmp-linux-x86_64/frida-python2.7/src/frida-ps
./build/frida-linux-x86_64/bin/frida-ps
afx237@bright ~/frida> ./build/frida-linux-x86_64/bin/frida-ps

Failed to load the Frida native extension: dynamic module does not define init function (init_frida)
Please ensure that the extension was compiled for Python 2.7.

This sounds like a mix-up of Python 2.x vs 3.x – are you using Python 3.x with the 3.x extension you compiled?

[oleavr]

Ahh yes, frida-ps and the other CLI tools installed by frida-python, pick up the default python:
#!/usr/bin/env python
So in the above output you seem to have the frida-python extension for python 3.x in your PYTHONPATH, and /usr/bin/env python presumably resolves to python 2.x.

Thanks, I've figured out with python (package manager in ARCH changes all python-related symlinks to Python3).

Right now,

1. I've started server on android device
2. performed adb port forward (according to manual)
3. performed easy_install
4. downloaded scripts from ospy.org/frida/linux/lib/python2.7/site-packages/frida
5. ...and when I run python ps.py -R

Any ideas what am I doing wrong ?)

Aha. I see what's going on here. This is my fault. The latest Frida release didn't produce a new Android binary, and turns out there's a compatibility issue that prevents the latest release from communicating with older frida-server binaries. If you redownload frida-server for Android, this issue should now be resolved.

Now it works ! Thank you!
