I want to debug android Lockscreen. I have full source code.
What i have found is Lockscreen.java(extends LinearLayout) is placed under frameworks\base\policy folder i.e. part of framework.
What i have found on internet/stackoverflow is, how to debug android framework service from system_process here
or how to debug framework from app(basically attach framework source code).
But How to debug something which is written as part of android framework(UI part like lockscreen) and not a service?
My problem is i have neither application nor it is a service.
I got the answer.
Problem was eclipse was not detecting framework code as application.
So i was not able to add framework code from "add->project" option.
What i have done now is, i added any dummy androidManifest.xml in policyfolder(eclipse detects only manifest file, not mk file, it seems).
So eclipse started to detect it as an application.
Now i started debug configurations and gave id of system_process and press debug and set the breakpoint.
it worked.
