Catching a logcat:

Whenever you QQ (cry) around because anything doesnt work, every dev can only guess, what s your problem. If you wanna provide the necessary information to him, give him a logcat and he will be happy and fix the bug you are getting.

Ricardo Cerqueira once posted this pic about this topic

So here is what you need to do, before you report the next bug/error to your dev.

1. Download QtADB from HERE (Find their HP here: http://qtadb.wordpress.com/)

2. Extract it to some place you wanna have it.

3. Now Open QtADB.exe

4. Connect your phone in debug mode

5. Click logcat on the left side (it's the last one)

6. Now Reproduce the problem, that you have, like force closes or other stuff.

7. Maybe reproduce it a second time

8. Push ctrl+A to mark all the lines

9. Right click it and choose, export selected to file

10. Save it to a place, where you can refind it.

11. Upload it somewhere (e.g. mediafire.com)

12. Post in the corresponding thread and give them a description of the error, so they know, what they need to look for and the link to the uploaded logcat.

This will improve a lot of ROMs around here, cause everyone uses it, but hardly anyone (including myself) can contribute to cooking/deving. So do us all the favour, that if you experiance an error and it's cause by the ROM and not a buggy installation, make a logcat and post it to the threads of the devs ;)

Here is how it typically looks (Zeus ROM v4.02 + LG kernel without dimming light):

Added ADB package, from my PC, which is needed from QtADB... See attachments ;)
