[GUIDE][HAVE A LOOK] DONT KNOW SOMETHING? Check here first!

The reason for this guide is that many new users would have difficulty to understand what are these short forms.. everyone says cwm, rom, cm, etc.. but no one says what it is.. and you may feel a bit shy/embarrassed to ask them what it is. So here is my attempt to cover them..

Please do let me know in PM if some words are missing and you want them to be covered.. i will gladly add them, thank you.

WITHIN ANDROID DEVICE METHOD:

This i learnt from paxChristos from his thread.

• 1. Logcat within android device can be done in one of two ways, through a Logcat app: Difficulty --> *
  Here are two good apps: aLogcat or Catlog
  Both of these programs can dump their logs to a text file, which is very useful for debugging. Or, you can do it in terminal emulator (same rules as running through adb(see below))

• 2. Through Terminal method: Difficulty --> **
• Install Android Terminal Emulator app from Play Store..
• Open terminal app you just installed..
• Enter these commands:
• After every command press ENTER/SUBMIT button
  
  Code:

  su

• then accept the superuser popup message[it comes only first time if you select checkbox "remember the choice"]
  
  Code:

  logcat -v long > /sdcard/test.log

  Or use this command:
  
  The -v long puts the text in a nice format that is more easily readable. The *:W will search for all warnings, errors, and fatals, while the *:S will silence everything else.
  So essentially, u will have a .txt file that has a log of all warnings and up, nothing else, and it'll look pretty too!
  
  Code:

  logcat -v long *:W*:S > /sdcard/filename.txt

• now press home button to minimize the terminal..
• and do the task which is giving problems/ whichever task log you need to give to dev..
• then drag the notification bar..
• select terminal app in it..
• now press and hold "Volume down button" and touch c button on keyboard.
• This will stop the command..
• now use this command twice
  
  Code:

  exit

• Now app will get closed. go to sdcard to find test.log file.. upload it to here so that dev can access it..

Thank you for reading it with patience hope you can get logcat now..


Note: if you are stuck in boot and want to take logcat.. READ LOGCAT FROM ADB METHOD BELOW.. the above one is simple method for these tasks for eg.. if you are having some force close of app/lag etc.. then after entering second command press enter and then use home button to minimize terminal.. dont worry it will take log.. now open that app and once it gives force close then click on it and then open terminal again and press volume down button + c to terminate command.. then use exit command two times... done.. now go to sdcard and find a.txt file


From PC[i.e, ADB] LOGCAT METHOD :Difficulty --> ***

There is an advantage here. As doing this way, you can start using logcat when your device boots. There are 2 ways here again..

PREPARATION:

• In your android device, go to settings --> applications --> development -->
• Check USB Debugging
• Make sure your device driver is already installed otherwise install kies software which will install drivers too.. Get kies from This LINK
• You need to download this ADB.zip file i made to your system.. Download link
• Extract the ADB.zip file from any applications like IZarc/7Zip/winzip/winrar.

ADB USAGE INSTRUCTIONS:

• Then go to Android folder.. inside that you should find 3 files.. Now open a command prompt or terminal in that path..(wherever you extracted it.. use cd command)
  Then inside that path.. type
  
  Code:

  adb logcat > filename.txt

  Or
  
  Code:

  logcat -v long > /sdcard/test.log

  Or
  
  Code:

  logcat -v long *:W*:S > /sdcard/filename.txt

• Now perform tasks in android device of which you need to give logcat for the devs. Then use CTRL+C to end the command.
• Now find the filename.txt inside the Android folder which has logcat. Upload this file and give link to dev..

The full list of options that can be used with logcat command 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 *:W with any other letter from above to get more info.



From PC[i.e, ADB] GET DMESG:Difficulty --> ***

Note: You will need adb access for this to work, same as logcat. Read PREPARATIONS above to find adb files required and related setup.

What this will do is get us live kernel output so we can know things like "What driver is the kernel loading {or not loading for that matter}" and similar things.

Go to Android folder.. inside that you should find 3 files.. Now open a command prompt or terminal in that path..(wherever you extracted it.. use cd command)
Then inside that path.. type To get last_kmsg:
From Android Device GET DMESG:Difficulty --> **
You can also get the dmesg by using terminal emulator.
To get last_kmsg:
FOR APP DEVS / ADVANCED USERS ONLY! LOGCAT INSTRUCTIONS:
Thanks to jaison thomas for this method! NOTE: I have not tested this. sorry. But it will definitely work. I edited the quoted message to make it simple.

jaison thomas said:

log cat using eclipse, i thought it will be simple for advanced users who are into app development.
I will guide how it works
1) install samsung kies in your pc
2) turn on usb debugging in phone.
3) install android plugin for eclipse .
4) now on eclipse click on "window" --> "show view" --> "other" --> "android" --> "log cat". Then click "ok".
Thats it .logcat window will be shown in lower bottom side of eclipse.it is having a green color icon. Also there may be a chance of logcat window minimised in eclipse.do look for a green icon.
5) now conect ur phone using datacable u can see all the things happening inside the phone in log cat window in eclipse.

NOTE: if you couldnt find android under other option.. Do this:
u didnt install android plugin for eclipse do as follows to install android plugin for eclipse.
1) click on help
2)click on install new software
3) then click on add.
4)then you will get a text box with name and location. in name text box type android or any thing,
in the location copy paste this
https://dl-ssl.google.com/android/eclipse/ and press ok,
5)In the Available Software dialog, select all check boxes and click Next.
6)In the next window, you'll see a list of the tools to be downloaded. Click Next.
7)Read and accept the license agreements, then click Finish.
8)If you get a security warning saying that the authenticity or validity of the software can't be established, click OK.
9)When the installation completes, restart Eclipse.

Welcome to LINK2SD app friends!
Easiest app to install and use to extend your internal memory.

What it does?
Steps to install and use link2sd[2.2.3 version]:

• Let the media scanner finish the scanning process, then open link2sd app and you will see a pop up menu "Select the file system of your SD card's second partition"
• Choose your partition type for "second partition" you created while partitioning, say you choose "FAT32/FAT16" then your sdcard second partition should be FAT32/FAT16 which is nothing but FAT or vFAT.
• Now Press OK. After 2-10 seconds you will see another pop up menu "Restart your phone" Press "OK" (message goes like this "Mount script created, please restart your phone to mount the second partition of your SD card.")
• Now do a reboot of your phone.
• Link2SD successfully installed.

To make space inside internal memory-->

* Now open LINK2SD app and you will see three buttons on top bar. click on the first button from left side. you will see:* Now select options button in phone, then select "Multi-Select". Now press "select all" option.

* Now press "Actions" button. In new pop up window select "Create link"

* Now in new page which appears, select all 3 options to link application, dalvik-cache, library files. Then press "ok" button and wait till the process ends. It will take time depending upon how many apps you have. around say 5 minutes.

* Now go to linked option from top bar first button from left side. and see al the apps having linked->sdacrd tag on them which means they are now in sdcard second partition..

*Long press on any app to view more options.


NOTE: 1. you cannot move link2sd app from internal memory. It is better to keep it there.
2. System applications should not be linked to SD card. Link2SD does not allow these applications to be linked.
3. Link2SD does not move application's private data directory; it moves apk, dex (dalvik-cache) and lib files.
4. Do not move keyboard apps to system memory. they wont work.


Advantages:

1. When you connect your phone to PC as mass storage, Android unmounts FAT partition but the second partition remains mounted in phone. Therefore linked applications are not affected and can be run without problems even when you have access through pc to sdcard.

2. You can use this app to uninstall system apps, move user apps to system apps or system apps to user apps.

3. You can integrate new updates of system apps which will be stored in internal memory to system apps. But please note: You should free the app first and then move them to/from system always for safety of apps so that they wont give FC. If some apps did gave FC after moving please restart the phone.

4. You can use clear cache, dalvik-cache, 2nd partition options. They wont harm your apps, they will remove only unwanted files.


Troubleshooting / Error occurance chances:
Question : When I click on "Move to SD card", I see a progress bar for 2-3 seconds and then:
pkg:/data/app/com.mobisystems.editor.office_registrered-1.apk Failure
[INSTALL_FAILED_INSUFFICIENT_STORAGE]

Answer : Your problem is a simple one.. your internal memory is low..

What link2sd actually does is.. first it moves the files to internal memory and then it sends to 2nd partition.. so you are having issues because.. say the apk file is 20 MB.. and your internal memory is around 20/less MB free.. So, it will give that error even if the second partition is totally empty..

For a work around to this.. you can make backup from titanium or just backup with any app.. then uninstall some apps.. then move that big app.. then reinstall these..

Hope your doubts are solved.. Enjoy the awesome app!
