Can I see the Logcat on the Android Phone itself,

Question

If yes, then how? Does Logcat also log events like starting time of application on its own, or the application has to use something like Log.v(App_name,message) at the start of the application?

Answer 1

There are a few applications in the market that will let you view the logcat on the phone. One example is aLogCat. Also, I'm pretty sure that it does log a message when the application gets loaded (certainly for the activity being started.

Answer 2

exactly Sashi : aLogCat is basical, but if you want your own reader, there is a special permission for this : Read_logs.

The least you can see is an entry from the ActivityManager : looking like this approx.

- Timestamp - INFO/ActivityManager(7703): Starting: Intent {act=android.intent.action.MAIN
cat= [android.intent.category.LAUNCHER]cmp=com.lemonde.androidapp/.SplashActivity 
bnds=[5,553][115,671] } from pid 7786

and here is an interesting tutorial

Good luck !
