[Completed] how to log adb logcat using .BAT Files - XDA Assist

Hi
I am using third party tool to perform android touch screen operation.
I wanna start and stop logging using batch files or python files.
example:
Clear log - > start logging -> play music -> stop logging -> save log file.
I tried to run 2 different files with
1. adb -s <DEVICE_ID> logcat -v time > "C:\Logfile.txt
2. ctrl+c
As i am using batch files, i cant send Ctrl+C separately as it is opening the ctrl+c in different window.
Please can anyone suggest how to start and stop logging.
I dont wanna use dump -d as it may not give complete log of all the operations I did. (not sure)
I am new to android.
Suggestions and help are appreciated.

[SCRIPT] Android-Linux Tools v0.2 for Linux [[Suggestions Needed]]

Okay. If this is not where the MODs want this post, please move it.
[UPDATE] - Jump over to Post #12 for some of my recent ideas and changes for this application.
I have been using mods for the G1 and the myTouch 3G for a little while now. I have used Backup for Root, and I use Nandroid. I created just a little simple script to backup your device to your linux-based machine and restore from there too. The concept behind this is having your backup on your computer, not your sd-card. Please, feel free to contribute. (If this is not your cup of tea, please do not leave a comment). I am limited on time, and wanted to contribute a little to the community. All this script is a compilation of adb commands. Anyone could compile these commands, I just wanted it organized and in one place.
README
After using all of the backup tools for root, I have ran into random FCs and bugs. This script uses Android SDK's adb tool and was designed to be simple. This script goes through and backs up your applications, bookmarks, sms, alarm clocks, settings, launcher settings and dictionary. There are plans for this script to be interactive in the future. As for now, it is a very basic script that will backup your device then restore your device.
Notes. As for now this script requires sudo. On every other linux pc tested, sudo was required (maybe because user did not install adb correctly?). This will change in future versions.

Nice script but bart.sh can accomplish a full backup of your Android environment for restoration at a later date. While it does it to the SD card initially, these "barts" can easily be copied to any computer. I can, however, see a use for this as it serves a slightly different purpose. Thanks.
I wasn't sure what response I would get to this post. I have had to flash, partition, format, wipe.. enough times that I just wanted to plugin into my computer, backup, wipe-flash then restore. Thanks!
nice. I don't use linux myself, but i see the point of having the backup else where (not an SD card attached to the phone itself).
will this, in theory be made to work on windows? Cause that will be awesome.
@str4vag It would be really simple to just use a .bat file for Windows. I don't have any plans on making a windows script anytime soon. Sorry. Same commands especially though.
This is exactly what I've been looking for, now I just need to mod it to sync apps/bookmarks/etc automatically whenever I plug in my phone, and to only sync the new items to keep it speedy, great work dev!
@ggolemg I can play around with some "real" features soon. I plan on having it archive your backups and allow you to select which backup (default is most recent) you would like to use. I am sure I can play around with your idea too. Thanks.
subscribing to the thread, idea is very interesting. i've been looking for a foolproof way to backup and restore bookmarks, sms messages, and different alarms, without all the issues of backup for root users. gonna check out the script tonight.
Update coming by the end of the week.
- Will only backup apps not already backed up.
- Possibly apply the Python interface I have developed.
- More goodies.
How about switchrom?
Android-Linux-Tools
Okay, so this week has been crazy for me. (Mind you I am a restaurant manager first and a developer (primary web) second). I think I am going to gear this project in a different direction. First off, I have created GTK2 Dialogs and a settings panel for this application. I would like to gear towards general linux tools on the pc side. So over the next two weeks you can expect,
- Graphical Interface for abrtool (Android-Backup-Restore)
- Configuration for each application.
- Nautilus Scripts for all applications.
- Right-Click to Encode Video (With GTK2 Dialog progress)
- Right-Click to Install APK (With GTK2 Dialog progress)
- Right-Click to Sign APK (With GTK2 Dialog progress)
- Right-Click to Copy Files to SD Card
- abrtool will backup to Ubuntu One Cloud (Simple adb pull ~/Ubuntu\ One/? or maybe play with the API?)
Ideas and Possibilities
- User.conf editor
- Select with applications to backup
- Switchrom features?
Any other thoughts or suggestions are welcome. I want to start simple, keep working on the abrtool and then make my way out to some other useful tools for us linux (Ubuntu) users. Let me know what you think and what would be helpful.
i had to make a bynch of edits so this dosent run as root, id recomend everyone do the same, only run root when you must. Also changed ,.adb to adb so i dont have to run it in my android sdk dir
@ahronzombi Can you post those changes?
I am a firm believer of only running root when needed, Like I mentioned before I don't really have a huge amount of time, and when I tested this on a friends notebook adb required root to atleast kill-server then you could perform shell/push/pull.
AFAIK, adb server only requires root if ou haven't set the proper udev rules for the device.
Exactly. If we want this script to run universally we cannot rely on all users to have added the udev rules. If they don't they have to run sudo. Maybe a quick check for the udev file then sudo if not?

no i think it would be wise to have people understand there udev permissions rather than run root so its universal. that kind of thinking leads to very big security problems. with root in the script most of the simplest linux users could exploit anyone
I fully understand that. Do you mind posting your changes to the script?
this is the secure version of the script that dosent run as root
keep in mind i set my own adb and home directorys so you'll have to change those

[WINDOWS][TUT]ADB tutorial, setting up ADB, usefull commands, collecting debug info.

Hi all.
Everyone here on our forum wants to help devs by testing different stuff but devs wants testers to send debug info to them so they can resolve bugs. Notifying bugs without logcats is useless and some users don't know how to collect these debug data.
To collect debug info there is a tool named ADB (Android Debugging Bridge). we r very small community and there are not plenty of sgr users around here so we have to worry about knowledgeable testers. so i m making this basic instructional guide to ADB. about how to set up ADB on windows and some basic usage.
Setting up ADB on windows.​
Know this first.
> ADB requires usb drivers. So first of all install kies so that ur pc detects ur phone and ADB can recognise ur phone.
> Android is linux based and in linux commands are case sensitive so while typing these command use propare case otherwise commands won't execute.
> Windows uses back slash [\] and linux uses forward slash [/] so while typing file locations. For location of file in ur pc use back slash and for files in ur phone/sd card use forward slash.
there are two ways to setup adb on ur windows pc.
1 > download the android sdk, it includes the adb
u can download latest android sdk from HERE.
2 > only download adb package, no need of downloading the whole sdk.
look at the end of post to find the zip file of adb package.
now after downloading:
if u have downloaded sdk read this:
> after downloading sdk, extract it to ur desired location.
> after extracting, open that folder and goto "platform-tools" folder.
> now hold the shift key and hit right click in that directory
> click "open command window here"
> u will see command promp, type "adb" in command prompt. if adb executes means u have successfully setup adb on ur windows.
if u r using without sdk:
> just extract the package
> hold shift key, hit right click and choose "open command prompt here"
> type "abd" in command prompt and check if adb executes.
now as we have successfully setup adb lets begin to some basic commands.
first of all connect ur phone using usb cable. make sure u have checked usb debugging in settings>applications>development>check usb debugging.
now open adb as mentioned above and type
Code:
adb devices
u should see
Code:
list of attached devices
xyz device
xyz will be name of ur device, as default it will be some number.
Basic usefull ADB commands​
1.
Code:
adb pull
this command can be used copy files from ur device to ur pc.
for eg.
Code:
adb pull /system/app/Camera.apk
this will copy the camera app to the directory where adb is extracted.
if u know the path u can copy anything using this command.
2.
Code:
adb push
this command can be used to push files to ur phone.
type the command, drag and drop the file in command prompt and than type location where u want to push that file and hit enter.
for eg, if i want to push image named android.jpg stored in my C drive.
Code:
adb push C:\android.jpg /sdcard/
this will push that image to sdcard.
sometimes we have to push some packages in specified folders. just type the location after file name.
for eg
Code:
abd push C:\sanim.zip /system/media
3.
Code:
adb install
with help of this command we can install apps to our phone dorectly from pc.
for eg. type "adb install" than leave one space with mouse choose apk file of app u want to install and drag and drop it in command prompt. path of that app will be displayed in command prompt. like this.
Code:
adb install C:\adb\Camera.apk
by executing this command u can install the app u have dragged and dropped in command prompt.
As i have written for windows but these commands can be used on ADB on linux/MacOS as well but i have only mentioned the set-up guide for windows only.

Getting Debug Infos (Logcats)​
1. logcat
logcat is a report from android logging system which runs in background from the moment u boot ur phone. and it haves all the info what went wrong with system.
generally we can see logcat by typing
Code:
adb logcat
but that will show the constant data flow so better save it as file so can be sent to dev or u can study it later.
Code:
adb logcat > log.txt
this will store the logcat to directory of adb and collect log in text file.
2. bugreport
Code:
adb bugreport
bug report prints dumpsys, dumpstate, and logcat data to the screen. which can be used for bug reporting.
3. Java Debug Wire Protocol
Code:
adb jdwp
this command prints the list of available JDWP processes on connected device in command prompt.
Logcats On Mobile​u can directly generate logcat on ur mobile using Terminal Emulator app, there are many terminal apps in market. CM comes with pre-loaded Terminal Emulator.
some terminal apps:
Android Terminal
Terminal Emulator
RomToolbox
u will need root access to generate logs
open terminal app, u will see following screen
Code:
$ export PATH=/data/local/bin:$PATH
$
now type su and hit enter.
allow super user permissions.
now to get a logcat type following command.
Code:
logcat > /mnt/sdcard/logcat.txt
this will generate text file named logcat.txt on root of ur sdcard which is containing logcat.
to get DMESG (Kernel Debug)
open terminal and type following command
Code:
su
dmesg > /mnt/sdcard/dmesg.txt
this will generate text file named dmesg.txt on root of ur sdcard which is containing kernel debug log.
Kernel Debugging.​
we can use adb to debug kernel issues.
Code:
adb shell
dmesg
this will generate a log which is very helpful to resolve kernel issues, we just have to send this log to dev, he will look after it.
sometimes after flashing kernel we go into bootloop in that cases generate logcat using this commands and send to dev it will be very helpfull for dev to know and resolve reason causing bootloop.
Code:
adb shell
cat /proc/last_kmsg > /sdcard/last_kmsg
this command should be executed immediately on reboot otherwise it will be over written by new kernel message. the file will be stored on root of ur sdcard named last_kmsg. send this file to kernel dev it will help him great to resolve the problem.
Read this if u dont know how to get files from ur sdcard even if ur phone is not booting and stuck at bootloop.
u must have CWM to do this.
>boot ur phone in recovery mode (by holding VOL UP and HOME key together on boot)
>goto "Mounts and Storage"
>Select "Mount USB Storage" and plug in your data cable.
>Now u can access ur sdcard on ur pc, after ur work is done click "Unmount"
Hi,
Just a noob question... if my phone is stuck in a bootloop, is there anyway for me to get a logcat without flashing a new rom???

Hello I am trying to create a batch file that has an infinite loop and was wondering if there are any adb commands that can do this.
I am also looking for an adb command that waits x amount of seconds before performing the next command.?
Any help would be greatly appreciated

[Guide]Noobs Guide to creating a logcat[All methods explained as of 20.1.2013]

Q. What is a logcat?
Ans. A logcat is a sort of written report for what things(operations like starting processes lot of dev related technical things) the phone is doing at a given time.
this guide shall provide simple step by step method (Will try to be very short and direct)
Why create this guide cause i found a lot of guides on this topic(Really a lot !!!)
But were written in a fairly roundabout manner so here is my attempt to simplify things.
Prerequisites : (Please read before doing anything)
For creating a logcat via computer :
1.ADB(Android Debugging Bridge) you can get a smaller version from here : ADB & logcat tools.zip else you can get it along with android SDK.
For creating a logcat via phone :
1.alogcat/catlog[APP]
OR
2.Terminal Emulator.[APP]
Ok down to business...
Via Computer (ADB) :
very useful cause you can start logcatting(Is there such term) even before booting.
open terminal at the location for ADB example for me its C:/ADB>
so now your teminal should look like this :
Code:
C:/ADB>
now connect your phone via USB and don't forget to tick Android Debugging option under app>development(2.3.x) or Developer Option>usb debugging(4.0.x & above) on your phone
now type this in the terminal
Code:
adb logcat -v long > name of problem.txt
nothing will happen on the terminal don't worry its working to end the logcat press ctrl+c.
you shall have a log file called name of problem.txt or whatever you thought of substituting that name of problem with inside your ADB folder.
Via Phone :
1.Via Terminal Emulator :
its same as for adb except you are already in the shell that is rather than doing adb to reach your phone and then command just enter the command simple
type this in your terminal emulator :
Code:
logcat -v long > name of problem.txt
to finish logging press vol down button + c
you will find a text file on your SD Card.
2.Via logcatting(still don't think its a word) APP

If you have any doubts or problem Private message me ...(I do not reply to hate mail,controversies,or doubts that i feel have been adressed to the best of my knowledge here)
Good Luck and hope this helps you to get other developers address your problems convincingly:good::highfive:
good tutoiral you could add some basic adb commands to the op..
Via Phone don't works for me. Do I need to install something before this?

After using generated image I'm getting 'System UI' has crashed. I'm unable to connect via adb as the error occurs at the very beginning of android runtime. I can see that my application has turned on, but I can't gather any logs.
To enable logs i'm trying the following method:
Appending init.rc in Android root with:
Code:
service logcat /system/bin/logcat -v long -f /mnt/sdcard/logcat.log
oneshot
This solution doesn't generate any logs. The logcat.log file doesn't exist.
I need the output to be stored either on internal or external sdcard. Could someone point me where I'm making a mistake ?

[Completed] Is there a forum dedicated to writing/using android commands in batch files?

More specifically, I want to get and share info about using hybrid adb/batch commands, like findstr with getvar/dumpsys/logcat, accessing/modifiying settings with adb in batch, using /bin and /xbin commands. Like that. Thanks!

Hi DoLooper
There are several coding forums but they're mostly for java, c and c++. The closest thing I could find is this thread > [WIN][TUTORIAL]HOW TO USE ADB,DDMS AND TAKE A LOGCAT {pictorial explanation}
