DUE TO REAL LIFE TIME CONSTRAINTS I AM UNABLE TO CONTINUE READING AND DIAGNOSING LOGS FOR MEMBERS. PLEASE USE THIS THREAD AS INTENDED, AS A STARTING POINT IN LEARNING TO READ THESE LOGS AND DIAGNOSE PROBLEMS YOURSELF. THANK YOU!
I'm starting this thread in hopes of sharing some very useful information to all our new members and hopefully either teaching something new or being a good refresher for our experienced members. I've been asked before how to tell what errors are present in logcats, how I can understand all that mess, etc...
Well, I'm going to try my best to explain all of it. In this way, you can get your own logs and try to fix the problems, or know exactly what is causing your problems to help out the developers so they aren't looking through thousands of lines of code for each persons issue.
Help us help you!
Due to the recent feature in the portal, my thread has become increasingly popular, and as such I am getting a lot of requests for help. You may post your logs here, but please do so in either pastebin format, or use hide tags. Please DO NOT request help via pm. This is for a couple of reasons:
- I can't keep up with all the requests.
- Your logs may be solved by another member, I have requested that any willing RC's, RD's, Moderators, or members willing to help, to do so.
- If you post your logs here, any member may look at it and help you solve them.
To begin with, we'll need to have some understanding of adb. Check out this thread by @bigtoysrock and be sure to thank him!
First, we'll need to know how to get a logcat. With the plethora of new users this has been the subject of many, many discussions. When asked to get a logcat, they don't know how.
Tools and Requirements
First of all, you'll absolutely NEED to have usb debugging enabled. To do this go to SETTINGS, navigate down to DEVELOPER OPTIONS and select it, if they are not on use the toggle in the top right corner and select USB DEBUGGING ( See attached screen shots )
Secondly, you'll absolutely NEED to have the ANDROID SDK grab it here
Install the SDK on the root of your computer. DO NOT change the SDK name to include any spaces as it will fail!
Also be sure to grab your device specific drivers, if they aren't already installed. Some devices will install them automatically, while others require a simple google search.
Now that you've got everything you need, lets grab a logcat!
Update: 15 Second ADB installer for windows is an excellent alternative for the above instructions, and while you're there be sure to thank @Snoop05
How to get a LogcatNavigate to where you've installed the sdk. Once you've gotten into the sdk, you're going to look for "PLATFORM TOOLS" folder, inside hold shift + right click on any empty space, select "OPEN COMMAND WINDOW HERE"
Connect your phone to your PC via usb cable, in the command window type "adb devices" without the quotes. If you've set everything up properly it should return an alpha-numeric value, this is your device ID. If not, you've missed a step or installed sdk in the wrong manner. Go back and double check your steps.
Now that we know you're connected there are a few options, you can run the logcat in command window, or you can export it to a .txt file.
To see the log in command window just type "adb logcat" (again no quotes) and the log will scroll through your screen. To stop scrolling so you can investigate hit ctrl + c
To export to a .txt file (I personally prefer this method) type "adb logcat > logcat.txt". You can name the logcat anything you want, for example "adb logcat > MyError.txt" just be sure not to include spaces or special characters in the name of the file.
Install your device driver for using adb. Everything you need will you find here
Download adb executable for your OS (Download: Windows | Linux | Mac). Paste it somewhere.
Connect your android device.
Verify if "Settings > Developer options > USB debugging" is checked, if not, simply check it.
Open a command promt (windows) or terminal (linux / mac). How to do it: On Windows: windows + r > enter "cmd" (without quotes) > click enter | On Linux: You don't know how to open a terminal? LOL | On Mac: Type Terminal into Spotlight and open it
CD to the directory where the adb executable is located. On Windows: Go to the directory where you downloaded the adb executable, Shift+Right Click and select "Open Console" (or similar) | On Linux / Mac: Rightclick in the directory and select "Open Terminal here" (or simply CD into the directory)
Type in your cmd/terminal: adb devices to verify your device is properly connected.
If your device is properly selected, type in adb logcat to show the mighty and magic logcat aka stacktrace.
Reproduce your error (or whatever) on your device.
Right after, paste the whole cmd / terminal window into a paste-service like http://pastebin.com/ and send it to us." - Quoted from Leandros here
