here is my problem. I am trying to modify the libril.so library of Android for my project. To do so, I have downloaded, built, and flashed on my Samsung Galaxy S3 the last version of cyogenmod (CM11).
To start with some modifications and check if everything works, I tried to create a file and write something. The code lines that I have inserted are something like:
I have inserted these lines in the "eventloop()" function of "/hardware/ril/libril/ril.cpp" and built again the system. Once flashed however, the file is never created. This is strange since that eventloop() function should be called very frequently by Android. I tried also to comment everything in the eventloop() but everything still works perfectly. Therefore, I have three questions:
1) What am I doing wrong?
2) Why I cannot see any of the changes I made on the phone?
3) How may I insert logs or printouts to such library files?
Thanks for any suggestion
