Filters help you in finding relevant information about your application and you can create a filter based on the application package name like com.abc.com. You can save this filter by any name. When you click on this filter, you will see only those logs which are from your application.
You can create a filter based on log tag which is related to a particular line of code, for example, if you have placed system.out to print the output then you can create a filter by a tag System.out. Then it will shortlist all the print output in the code. You can create a filter by Choreographer which helps in finding the skipped frames if you want to see them. You can create filters corresponding to your PID and log message.
