Generally  I do this command  adb shell ps  in prompt  allows to see processes running  and it s possible to discover aplication s pid  With this pid in hands  go to Eclipse and write pid XXXX  XXXX is the application pid  then logs output is filtered by this application   Or  in a easier way    in logcat view on Eclipse  search for any word related with your desired application  discover the pid  and then do a filter by pid  pid XXXX

Suppose your application named MyApp contains the following components    MyActivity1 MyActivity2 MyActivity3 MyService   In order to filter the logging output from your application MyApp using logcat you would type the following   adb logcat MyActivity1 v MyActivity2 v MyActivity3 v MyService v   s   However this requires you to know the TAG names for all of the components in your application rather than filtering using the application name MyApp  See logcat for specifics   One solution to allow filtering at the application level would be to add a prefix to each of your unique TAG s    MyAppActivity1 MyAppActivity2 MyAppActivity3 MyAppService   Now a wild card filter on the logcat output can be performed using the TAG prefix    adb logcat   grep MyApp   The result will be the output from the entire application

I have found an app on the store which can show the name   process of a log  Since Android Studio just puts a     on the logs being generated by the other processes  I found it useful to know which process is generating this log  But still this app is missing the filter by the process name  You can find it here

Use fully qualified class names for your log tags   public class MyActivity extends Activity     private static final String TAG   MyActivity class getName        Then  Log i TAG   hi      Then use grep  adb logcat   grep com myapp

This is probably the simplest solution    On top of a solution from Tom Mulcahy  you can further simplify it like below   alias logcat  adb logcat   grep  adb shell ps   egrep   bcom your package name b    cut -c10-15     Usage is easy as normal alias  Just type the command in your shell   logcat   The alias setup makes it handy  And the regex makes it robust for multi-process apps  assuming you care about the main process only    Of coz you can set more aliases for each process as you please  Or use hegazy s solution      In addition  if you want to set logging levels  it is  alias logcat-w  adb logcat   W   grep  adb shell ps   egrep   bcom your package name b    cut -c10-15

Edit  The original is below  When one Android Studio didn t exist  But if you want to filter on your entire application I would use pidcat for terminal viewing or Android Studio  Using pidcat instead of logcat then the tags don t need to be the application  You can just call it with pidcat com your application  You should use your own tag  look at  http   developer android com reference android util Log html   Like     Log d  AlexeysActivity   what you want to log      And then when you want to read the log use    adb logcat -s AlexeysActivity    That filters out everything that doesn t use the same tag

If you could live with the fact that you log are coming from an extra terminal window  I could recommend pidcat  Take only the package name and tracks PID changes

User · Answer

What I usually do is have a separate filter by PID which would be the equivalent of the current session  But of course it changes every time you run the application  Not good  but it s the only way the have all the info about the app regardless of the log tag
