Spend enough time around these forums and you will eventually see a developer request a logcat from users experiencing issues. Logcat is the command to view the internal logs of any Android system. Viewing a logcat is usually the best, and in some cases, the only way to diagnose a problem. Oddly enough, many Android enthusiasts do not know what a logcat is or how to pull one. Now, thanks to XDA Forum Moderator paxChristos, we have a thread dedicated to all that is logcat.
In the thread, paxChristos outlines the different ways to pull a logcat, and lists step-by-step instructions on how do it successfully. The thread covers pulling a logcat through ADB in detail, complete with an example of a mock output file. Each line in the mock output file is explained so not only will you know how to pull a logcat, you will be able to read and understand one as well.
If you’re interested in learning how to obtain a logcat, head over to the original thread. In the future when a developer requests a logcat, you will be able to provide him or her with the information they need to fix any problems that occur.___________________
