Native debug on Android

Question

It has been a few years since I last needed to debug any native applications on Android. After poking around a bit I found this Google reference referring to gdbserver and gdbclient.py.

I found the former in the NDK

$NDK/prebuilt/android-arm[64]/gdbserver/gdbserver

And the latter in the SDK

$SDK/development/scripts/gdbclient.py

When I went to run the python script I am met with:

$ python gdbclient.py
Traceback (most recent call last):
  File "gdbclient.py", line 27, in <module>
    import gdbrunner
ImportError: No module named gdbrunner

For the life of me I cannot find any information on what gdbrunner is. Nor have I found any other reference to it in the [S/N]DKs.

Any idea? Is there another method to debug native components of Android not reliant upon this script?

I fear I overlooked it in the NDK. I must have been using an older version. The gdbrunner package is located at

$NDK/python-packages/gdbrunner

Along with other useful things.

you can try this:

1.in app/build.gradle:

at dependencies label:

releaseCompile project(path: ':youModuleName', configuration: 'release')
debugCompile project(path: ':youModuleName', configuration: 'debug')

2.in youModule/build.gradle:

at android label:

publishNonDefault true
