This is not necessary, to catch every line of code.
Register an uncaught-exception-handler
(Thread.setDefaultUncaughtExceptionHandler). Before you set it, get
the current one. You may need to call it from your own uncaught-
exception-handler.
In this handler, print out the stack-trace (and some other info such
as OS-version, phone model, make, etc) to a file (on phone-memory or
sd-card)
These above steps are the bare basics.
In my app, I added a Service and an Activity, both running in a
different process than my app whose stack-traces i'm logging. If they
would run in the same process, it woudn't work (calling a Service and
Activity from a dying process).
The uncaught-exception-handling code binds to the Service
(initialization) and upon a stack-trace dump, after having generated
the file, it does a Service-request:
The Service starts the Activity that just shows a dialog asking the
using to submit an error report or not. If the user answers 'Yes',
then the Activity will read the file with the stack-trace info and
send it to a web-server (Http). The web-server gets this request,
generates an e-mail from it that is then sent to my inbox.
When the uncaught-exception-handler calls the service, it just kills
and extis the process. If the handler could not bind to the Service or
the Service-request failed, it calls the original default uncaught-
exception-handler that then shows the common 'Force Close' dialog.
This has been working well for me and found a few bugs here and
there :)
