Hi,
I am trying to debug some code in SystemServer.java file.
Initially, "power.init(context, lights, ActivityManagerService.self(),
battery);" was there. To Debug this, i am using "android.os.Debug" class
which will provide method call tracing.
So i added two lines for debugging
android.os.Debug.startMethodTracingDdms(35000, MAX_PRIORITY);
//===================================
added
power.init(context, lights, ActivityManagerService.self(),
battery);
android.os.Debug.stopMethodTracing();
//===================================
added
Noting else is changed, But still i am getting below error. If i will added
above two lines some where else in the code then i am not getting any
error!!!!!
Most of the time any thing is wrong i am getting following error in "System
Content Providers", "Input Method Service" and "Accessibility Manager". Why?
Anyone has any idea what is wrong in this.
