[Guide]Howto LOGCAT - Galaxy Ace S5830 Android Development

I think this one is definitely needed for this forum. So posting this here.
Here's how to use logcat:
There are two main ways to do a logcat, within android, and through adb.
Logcat within android can be done one of two ways, through a Logcat app:
Here are two good examples are either: aLogcat or Catlog
I prefer catlog, because in my opinion it has a little bit nicer UI. Both of these programs can dump their logs to a txt file, which is very useful for debugging. Or, you can do it in terminal emulator (same rules as running through adb(see below))
From Moscow Desire:
On the other hand, using adb to run logcat, in my opinion is much more useful, because you can start using it when android boots (i.e. once the boot animation appears.)
The code for logcat to output to a file is
Code:
adb logcat > name of problem.txt
you can also do
Code:
adb logcat -f name of problem.txt
how I prefer to do it is this way:
Code:
adb logcat -v long > name of problem.txt
with the -v flag & the long argument, it changes output to long style, which means every line of logcat will be on its own line (makes it a little neater, imo)
Note: When outputting to a file, you will see a newline, but nothing printed, this is normal. To stop logcat from writting to a file, you need to press ctrl+c.
Here's where using logcat (via adb makes life really easy)
Lets say you find a problem you're having after looking at a logcat.
For example:
When I was trying to use a different ramdisk, wifi wouldn't work so I got a logcat that's almost 1300 lines long (a lot of stuff happens in the background)
So if you are searching for an error in the logcat file (it's always e/ for error, f/ for fatal. Those are the two main things that will break a system.)
Code:

D/wpa_supplicant( 930): key_mgmt: 0x4
(mind you, that's 29 lines out of 1300ish, just for example)
I then could do the following with logcat:
Code:
adb logcat WifiStateMachine:E *:S -v long > name of problem.txt
and this will only print out any errors associated with WifiStateMachine, and anything which is fatal, which makes it about a million times easier to figure out what's going on!
In WifiStateMachine:E, the :E = to look for Errors, the full list of options is as follows:
V — Verbose (lowest priority)
D — Debug
I — Info (default priority)
W — Warning
E — Error
F — Fatal
S — Silent (highest priority, on which nothing is ever printed)
You can replace the :E with any other letter from above to get more info.
In order to filter out anything other than what you are looking for (in this case, WifiStateMachine) you must put a *:S after your last command (i.e. WifiStateMachine:E ThemeChoose:V ... ... AndroidRuntime:E *:S)

Great Guide! Should become a sticky.

You know,today morning you said you were not an expert with logcats.I see this thread and i am awestruck,but then i read the second last line :|

I said i am no expert. That doesn't mean i cannot take, read or understand logcat..!!

This thread is perfect to be a sticky in the Android Development Section.
Newcommers should know how to properly report bugs. I also leave a redirect in the Original Android Development.

I rather use ddms for all

Command prompt is the most basic thing same old Windows

helped me out. Thanks

Fro "noobs" it will be easier to use qtadb https://qtadb.wordpress.com/download/ , just download, install and run. Nice GUI for adb, contains access to logcat too.

Extremely useful,
thank you!
However, catlog force closes when I added it as system app.

How can i get application specific logcat like i want to get logcat of systemui only

Really helpful!

Emulate a ROM

Is it possible to emulate an android ROM on a computer?
If you grab the SDK, you can run any version of Android in the emulator. If you want to run an actual ROM you will need to create an image of /system (as system.img) and replace that with those in the SDK folder.
thanks alot! that helped me alot
and yes, i want to run an actual ROM. what filesystem does it have to be?
was thinking about something like...
(cd PATH)
dd if=/dev/zero of=system bs=1024 count=#KB_needed
losetup /dev/loop0 system
mkfs -f FS /dev/loop0
(mkdir /mnt/system)
mount /dev/loop0 /mnt/system/
cp -a system /mnt/system/
umount /mnt/system/
losetup -d /dev/loop0
do you know any good tools for this exept for dd?
Never tried so I honestly don't know, you sound like you know a lot more than me about creating/mounting images than me, so it's probably best to use your judement. The easiest way is just to make a nadroid back backup, flash the ROM you want to test, nadroid that and grab system.img, revert to your old nandroid backup. It's tedious, and it doesn't help if you want to test a ROM before flashing, but that's the only method I've heard people use.
okay. thanks
HTC Sense UI system.img
Does anybody know where I can download a system.img for a HTC with Sense UI (Hero for example)? I have been looking for ages with no luck.
My app is not working on a customers Hero and I am trying to find a Hero system.img to run in the emulator so I can work out why it fails on this phone.
I dont own a Hero, so am unable to extract my own system.img.
You can get HTC official ROMs here:
http://forum.xda-developers.com/showthread.php?t=559622
if you've got a windows computer you probably could extract the content of this exe file and then try to follow my previous instructions to make the system.img.
And if you don't have an unix/linux box.. You could send the content of the exe file to me, if you are able to extract the data in it. (I'm in China with a netbook atm and not able to extract the exe file with my limited tools). Then I could try to make you a system.img
I tried that, but without an HTC phone connected to the PC USB the exe wont extract.
I take that back. I found the files in my temp folder. I have extracted ROM.zip including the system.img into the avd folder, but the emulator is failing to bring it up.
could you upload that zip file here or on rapidshare? then i could have a look at it
Here is the rom.zip file from RUU_Hero_HTC_WWE_2.73.405.38_WWE_release_signed_NoDriver.exe:
rom.zip
Other people must be doing this kindof thing to test their apps?
Here is the logcat. It looks like the sytem process is starting to come up, then fails. This repeats over and over.

Anybody?
Someone must have emulated HTC Touch / Sense UI?!
Okay... After unzipping and manipulating a 2.1 ROM to my liking; I have now resigned it...
Can someone please explain to me how I would go about testing it with the Android SDK Emulator?
I have already created a 2.1 AVD and the emulator loads to the "ANDROID" screen...
What must I do to test out this newly packaged ROM file?

[Q] Installation error: INSTALL_FAILED_INSUFFICIENT_STORAGE

I was working on an app and after I uploaded a *.ttf to the assets folder I went to run my app in the android emulator. It uploaded okay but during installation I got

If anyone knows whats up with that I would be greatly helped.
I figured it out, I just didnt give my emulator enough memory. stupid easy fix.

Since android development and logcat is essential part to track problems and errors..
The three most important log types are:
logcat: the log output of the Android system
radio logcat: the log output of your System / BB / RIL communication
kernel log (kmsg / dmesg): the kernel messages
Additionally there's the last_kmsg which is a dump of the kernel log until the last shutdown.
The tool I made will make you able to do all of these in very friendly interface, and even you could do more,, So let's see how it is
How to use:
It is simple, just run AIO_Logcat_Manager.bat file.. I will explain every feature in next heading.
Walkthrough Features:
Splash screen:
The main screen:
In this main menu, you can choose the type of logcat you want,, All, Error, Fatal, Radio, Kernel... etc
Process logcat filtered by name menu (Option 9):
This is unique in my tool, where you can filter your result logcat for specific process name..
Example: assume you get this logcat
Code:

and you want to see MediaPlayerService process logcat only..!!
So here comes the useful feature of this tool, where you can filter the only process you are interested in..
Read Exported logcats (Option 10):
Here you can read all logcats you have exported to the output folder
Kernel logcats (Option 11):
This feature needs from the user to be rooted in order to access kernel logs..!!!
Here you have the ability either to read or to export different kernel log types..

Thanks for this man. Helpful to everyone! Maybe you could add an option in the future to read logcats already made from ADB. Just a thought if you don't already have it
If I may make a suggestion, it would be a great idea to possibly include something like logcat-color to make viewing of real-time logs a lot easier
Great tool by the way

Yeah sure.. but java coding is different from cmd; however it is possible, but it will be very very long scripting if I am using cmd for that. May be I will try to learn some java coding later on, but not in the mean time..
Thanks for suggestion :good:
Thanks for sharing this

I get this error: "Unable to open log device '/dev/log/main': No such file or directory" in the log file. Using ezaechiel TW ROM on a Galaxy Note 1. There's no file called 'main' in the folder '/dev/log/'
Any ideas?
Ok managed to get logcat to work, found '/system/etc/init.d/12cleaner' had
Code:
if [ -e /dev/log/main ]
then
rm -f /dev/log/main
Which I commented out and now it's working.

No, for the logcat to work, the system needs to at least start. You can probably grab a kernel log, but I don't think it will show you what you want.

[GUIDE] How to Logcat

Here's how to use logcat:
There are two main ways to do a logcat, within android, and through adb.
Logcat within android can be done one of two ways, through a Logcat app:
Here are two good examples are either: aLogcat or Catlog
I prefer catlog, because in my opinion it has a little bit nicer UI. Both of these programs can dump their logs to a txt file, which is very useful for debugging. Or, you can do it in terminal emulator (same rules as running through adb(see below))
On the other hand, using adb to run logcat, in my opinion is much more useful, because you can start using it when android boots (i.e. once the boot animation appears.)
The code for logcat to output to a file is
Code:
adb logcat > name of problem.txt
you can also do
Code:
adb logcat -f name of problem.txt
how I prefer to do it is this way:
Code:
adb logcat -v long > name of problem.txt
with the -v flag & the long argument, it changes output to long style, which means every line of logcat will be on its own line (makes it a little neater, imo)
Note: When outputting to a file, you will see a newline, but nothing printed, this is normal. To stop logcat from writting to a file, you need to press ctrl+c.
Here's where using logcat (via adb makes life really easy)
Lets say you find a problem you're having after looking at a logcat.
For example:
When I was trying to use a different ramdisk, wifi wouldn't work so I got a logcat that's almost 1300 lines long (a lot of stuff happens in the background)
So if you are searching for an error in the logcat file (it's always e/ for error, f/ for fatal. Those are the two main things that will break a system.)

D/wpa_supplicant( 930): key_mgmt: 0x4
(mind you, that's 29 lines out of 1300ish, just for example)
I then could do the following with logcat:
Code:
adb logcat WifiStateMachine:E *:S -v long > name of problem.txt
and this will only print out any errors associated with WifiStateMachine, and anything which is fatal, which makes it about a million times easier to figure out what's going on!
In WifiStateMachine:E, the :E = to look for Errors, the full list of options is as follows:
V — Verbose (lowest priority)
D — Debug
I — Info (default priority)
W — Warning
E — Error
F — Fatal
S — Silent (highest priority, on which nothing is ever printed)
You can replace the :E with any other letter from above to get more info.
In order to filter out anything other than what you are looking for (in this case, WifiStateMachine) you must put a *:S after your last command (i.e. WifiStateMachine:E ThemeChoose:V ... ... AndroidRuntime:E *:S)

Logcat gives you the messages of the system logs and you can submit them to a developer manually. Bug report is kinda an automatic thing that keeps track of your errors

[SOLVED][Q] Commands not properly executing

EDIT:
The problem was that i was trying to read a line from the inputreader, when there was no line, so it was waiting for a response there...
Hello,
I am currently building an app to fix a little problem that exists on some devices with the wifi-mac and bluetooth addresses constantly changing (for me it's a N4 but I read somewhere that there are other devices with that problem too)
The thing the app should do is (steps taken from another xda thread: http://forum.xda-developers.com/showpost.php?p=43164157&postcount=1 )
- Mount /persist
- create the folders wifi and bluetooth
- create a text file in each of these directories containing the addresses that should be used in future
- fix the owners and permissions of these files and directories
- execute /system/bin/conn_init as su
The app is mostly done but somehow not working at all.
Everything from generating random adresses to saving them in a temporary file seems to work fine, but as soon as I try to mount the persist directory, the app stops to react.
At first, this was the first thing done by the SU Shell class that I wrote for executing su shell commands, so I thought that might be not working, but when I let that execute echo test it returns test just fine...
The code that is used could be expressed like that (this is missing some debug info and strings that get passed, but it should technically have the same result):
Code:
try {
shell = Runtime.getRuntime().exec("su");
outputStream = new DataOutputStream(shell.getOutputStream());
inputStream = new BufferedReader(new InputStreamReader(shell.getInputStream()));
outputStream.writeBytes("mount /dev/block/mmcblk0p20 /persist");
outputStream.flush();
} catch (IOException e) {
e.printStackTrace();
}
The attached zip file contains my main activity and the before mentioned su shell.
The complete source code of the app is available via my git server: http://greensserver.redirectme.net/greenchris/WiFi-MAC-and-Bluetooth-Adress-Fix.git
Does anybody have an idea why this isn't working?
Greetings
GreenChris

I forgot to add the logcat...
