How To Install The Android Sdk and Adb and Fastboot in Linux

!! THIS TUTORIAL IS All Linux Distros
!!START -------------------------------------- Optional
You will now install the SDK.​
!!START -------------------------------------- Installing Android SDK --------------------------------------
Installing the SDK is the easiest of all.
Download the SDK.169.9 MB [http://developer.android.com/sdk/]​
Right-click and select Extract Here.
Move the contents of the android-sdk-linux_x??-??_ directory to your desired location.If you followed Optional Installation, move the contents to your /AndroidSDK directory in the root of your filesystem.​
Close directory window.
-------------------------------------- Installing Android SDK -------------------------------------- END!!​
You will now set up your bashrc file and UDEV to recognize your HTC Device.​
!!START -------------------------------------- ADB + FASTBOOT --------------------------------------
The Android Debug Bridge (adb) is one of the tools that will help you the most when you run into flashing problems or running shell commands directly from your machine. UDEV will not recognize your G1 out of the box, but we will configure it with some rules so it can connect.
We will work with /AndroidSDK as the location of your sdk. If this is not your setup, I think you're smart enough to figure it out.
Editing .bashrc file to use tools from /AndroidSDK/tools/ directory -
Go to your home folder.Example: /home/wddglr/​
Press Control + H to view hidden files.
Look for your .bashrc file and double click to open it with gedit.
Add the following lines to the top of the file:
Code:
#AndroidDev PATH
export PATH=${PATH}:/AndroidSDK/tools
IMPORTANT NOTE​
Setting up UDEV to recognize HTC Device -
Type the following into a terminal (Applications > Accessories > Terminal):
Code:
gksudo gedit /etc/udev/rules.d/51-android.rules
Now add the following line to the blank file:
Code:
SUBSYSTEM=="usb", SYSFS{idVendor}=="0bb4", MODE="0666"
SUBSYSTEM=="usb", SYSFS{idVendor}=="18d1", MODE="0666"
Click save and close.
To restart udev, open up a terminal and enter:
Code:
sudo /etc/init.d/udev restart
Setting up fastboot -
Download this fastboot binary from http://android-dls.com.130.4 KB [http://android-dls.com/files/linux/fastboot]​
Once downloaded to your desktop, right click and select Properties.
Navigate to the Permissions tab and configure the following option:Execute: [√] Allow executing file as program​
Click Close.
Move the fastboot bianary to your /AndroidSDK/tools/ directory.
Reboot.
-------------------------------------- ADB + FASTBOOT -------------------------------------- END!!​
Thank to http://forum.xda-developers.com/showthread.php?t=537508 for making this for the g1

In newer versions of Debian based systems "sudo /etc/init.d/udev restart" will not work as the command have been changed..
Instead use: "sudo restart udev"
BTW, thanks for a very useful post

In modern distros, none of this nonsense is necessary. Download and extract the SDK, use it. No udev tinkering.

In Slackware it's /etc/rc.d/rc.udev restart and probably something similar with anything using a BSD-style init.
This is nice, but like so many linux how-tos I see these days, it's really a ubuntu how-to. Anything with a "g" in front of it (gksudo, gedit) will probably only work on half of linux boxes.

how do you find out what vendor ids to use for other devices? I see the first one here http://developer.android.com/guide/developing/device.html but what about the second one?

[TUT] ADB Guide

Hopefully this helps someone...
If something doesn't work here let me know and I'll add it and make corrections. I will gladly accept recommendations and input from anyone. Also Mac and Linux users please post your info and I'll gladly add your pieces to my guide as well.
Step 1:
Some files are needed such as the SDK and USB driver. Note: Some devices require Windows drivers provided by the manufacturer we will have to play around and see what works with Adam...
System Requirements
USB Drivers
Android SDK
- Download the zip file
Step 2:
Extract the zip and run the exe to install. It should check for JAVA dependencies and get you all setup.
Copy the SDK folder to the root of your C: drive or where ever you want. Plug in the device (Adam in this case), DO NOT MOUNT ANYTHING, and when prompted install the USB driver. NOTE: I'm not sure yet if the drivers in the link will work with Adam or not so play around and see what works. You can always go into Device Manager and remove the driver.
Step 3:
Create environment variables for ADB by right-clicking on "My Computer" and select Properties. Then go to Advanced tab (or Advanced Settings in Vista) and select Environment Variables. Add the following:
Variable name: adb
Variable value: C:\android-sdk-windows\tools
Note: that variable value may change if you do not run the sdk from the root of your C: drive and depending on the name of your SDK folder...
Step 4:
Code:
adb [COMMAND]
If you replace "[COMMAND]" with an adb command, the above should work for you. Go here for a listing of ADB commands...
A simple command to test with is:
Code:
adb shell
"adb shell" should return one of two values, "$" or "#". And this should be the shell prompt from the device, not your local terminal window.
If that code didn't work, put in your full SDK folder path and try again. If it works that way, look into the environment variable and make sure its the same as the path to your SDK folder.
References:
The first is the sweet guide from XDA member VanillaTbone and is widely used here at XDA.
The second is one I wrote over at NotionInkHacks. This one is only for Windows at the time being, but once people with other OSs leave feedback I will update to include those other OSs as well.

Thanks for the links!
They were helpful to me and I am sure they will be to others.

Thank you, stickied! This is useful to people unfamiliar with ADB.

Updated the OP so this is now a full guide. I also updated the title to reflect tutorial.

How to get your Adam detected in Windows
After following this.. you can follow this next to now make sure windows detects your Adam.
http://forum.xda-developers.com/showthread.php?p=12022670#post12022670

it would be more uniform if people installed the .exe and have 2 paths for step 3 depending on 64 bit or 32 bit
for 64 bit when installing the exe the path is
C:\Program Files (x86)\Android\android-sdk-windows\platform-tools
and for 32 bit I believe its (not sure on this one because I have 64 bit)
C:\Program Files\Android\android-sdk-windows\platform-tools
Also might be wise to mention that if you do not define a push or pull path way when you start up the command prompt it will look in C:\users\"UserName"

howdy,
I have previously installed the adb driver for my sgs and sgs2. When I plug in my adam, the mass storage components come up, but nothing shows up with regards to android devices which will allow me to update the driver for.
Debugging is enabled on my adam (it is a PixelQi/Wifi version running beast+clemsync v3) and shows up in the notifications. USB Mass storage works fine.
ADB also works fine for my SGS2 when I plug it in and run adb shell/devices. When I plug my adam in, adb does not see anything related to it.
Where should I go from here to get windows to like this thing?

When I plug it in I can see these things:

[Q] Help! Setting Up ADB Shell in Linux

I followed all of these instructions. Link: Here
But when I try to navigate to AndroidSDK folder in my home directory I can't get adb shell to start.
Code:
cd ~/AndroidSDK/tools
adb shell
After that the terminal says command not found and stuff.....anyone know how to set up adb shell on linux? (I'm running linux mint 10 specifically but I am a experienced linux user, i've used ubuntu and linux mint 10, so if you give me ubuntu commands for fixing this i can convert them into linux mint commands if need be).
Thanks for helping me get this set up on linux. I've mainly been a windows user and as easy as it would be for me to dual boot into windows instead i'm trying to make linux my main operating system slowly b/c i'm liking this operating system more than windows 7. so before i do that I want to make sure i know how to complete all the task i would want to do on windows 7 on linux instead, starting with adb shell

Those instructions are for an earlier version of android SDK. I am sure you downloaded and installed the latest from google's official website. If so, the adb command has moved to a different folder - platform-tools.
Do a search in the android sdk folder for "adb.exe", you should be able to find it and then use that folder as your base adb folder. Alternatively, you can setup the folder to be part of the path, that way you can execute adb from anywhere. If you need help, let me know.

What I found when setting up mine on linux was to start adb, navigate to the tools directory where you have it setup, and use the command "./adb shell" minus the quotes. This seems to work fine, I don't know why. I beat my head against the wall, and don't remember how I found out about this. It's safe to say, the ./adb should need to be used with all the adb commands.

Kifno check the dev section for my thread on how to install adb on Ubuntu should help you out. It might be buried but I posted a full guide.
Edit---- If you look on my thread on how to indtall adb in windows. On the bottom of the post its a link to my other thread..
Yea it's me Again. With the
Modified .HERO.

Step-by-step guide to setting up android sdk on linux:
1. On your linux box, go to http://developer.android.com/sdk/index.html and download the package for linux
2. Create a "androidsdk" folder in your home folder
3. Unzip the contents of the "android-sdk-linux_x86" from inside the tgz file - into the above folder. You should have "add-ons", "platforms", "tools" and "SDK-readme.txt" in the above folder
4. Open a terminal window and navigate to androidsdk -> tools directory
5. Execute command "android" without quotes - this should open a UI
6. Go to available packages and install all packages you need
7. Once it has installed everything, exit the application
8. Navigate to your androidsdk/platform-tools directory - you should have adb there.
Now you can run adb from here or setup your computer to run from anywhere - following steps are to setup so that you can run adb from anywhere...
1. Append the following code in your .profile file - replacing "full path to your platform-tools directory" with the actual path with quotes:
if [ -d "full path to your platform-tools directory" ] ; then
PATH="full path to your platform-tools directory:$PATH"
fi
2. Save your .profile
3. Logout and log back in.
Now you should be able to execute adb from anywhere on the linux box, when you login using your credentials.

Click to expand...
Click to collapse
the bold is where i'm having trouble....where is the .profile file located?
also would this be the correct full path leading to platform tools? (so i can know when i get ready to do the .profile file thingy once you explain that)
~/AndroidSDK/platform-tools
btw thanks for the help (clicking thanks button.....lol)
edit: i also just got this problem
Code:
kevin-Satellite-L305 platform-tools # ./adb shell
error: insufficient permissions for device
it won't let me launch adb shell even after i typed su and put in my password

.profile is in your home directory. You can get to your home directory from anywhere in linux by typing "cd $HOME" at the shell prompt without quotes and as is here. If you know of DOS, you can relate to a .profile file as an autoexec.bat, that executes everytime a user logs in.
You need the absolute path to the platform-tools folder - which you can get by being in that folder and typing "pwd" without quotes.
The last error, it has something to do with your computer OS not recognizing your device.
1. Go to /etc/udev/rules.d
2. Look for a file 99-android.rules - if one does not exist, create one
3. Append the following line to the file: SUBSYSTEM=="usb", SYSFS{idVendor}=="0bb4", OWNER="linux user name" GROUP="linux user group", replacing linux user name and linux user group with the actual values.
4. Save the file and restart your computer
This should do it.

[GUIDE][ADB]Easiest How to use adb, logcat, etc for noobs and newbies

ADB:-
Android Debug Bridge
Very useful program made itself by Google for Programmers and developers. Its based on command line and basically communicates with your Android to respond to certain commands. There is vast amount of knowledge about adb but its most useful commands limit to getting:-
Logcat:-
A real time log of what is happening in background of our devices. It is really useful for developers to see which component has malfunctioned and helps to narrow down their search for what failed and what needs to be fixed. Several times users are asked to give logcats of their devices which are giving errors. We will go in detail that how to get logcats in every and easiest way possible.
App Installation and Management:-
adb proves really handy if you want to install apks directly from your PC or want to batch install or delete them.
Shell Execution:-
You must have heard of Terminal Emulator. It is an app for android to execute shell commands(linux commands) which are basically present as applets in /system/bin, /system/sbin or /system/xbin(in our case) folders. A very imporant applet called busybox is installed there mainly used for execution of basic commands during root browsing or ROM installation. Many times updater script of ROMs use busybox commands to install it. Well, these commands can be initiated from your device too but they can be initiated from adb also making it easy for programmers.
Pushing and Pulling:-
Most used commands of adb. adb makes it a piece of cake for new device developers to get an ideo of structure and basic knowledge of devices by pulling command. We can pull out i.e copy any files or folders from our devices to our PC, even the root directories without rooting the devices. It help rooters and ROM chefs of new devices to get an idea and implement their mods on them. Pushing is also very useful command. It copies your files and folders from PC to your device. Very useful in pushing some /system apps and other things
Remounting and setting permissions
Basic commands:-
Of-course basic commands such as rebooting and rebooting in recovery mode and download mode are supported.
Others:-
There are several other features of adb such as fastboot, aapt, etc
Setting up ADB
Pre Requirements:-
PC(This is a windows guide, if asked I will add linux and mac guide later)
Java Runtime environment or Java Developing kit
Your Device Drivers
An Android Device
USB Debugging MUST be turned ON in the device for ADB to see it & Developer options is hidden in Android 4.2 and
above, Hitting Build number 10 times in
About Phone/Tablet reveals the menu (Thanks lilHermit for reminding me to add it)
Assuming you all these ready and working properly, we continue
If you are having trouble completing Pre-Requisites, there are several guides featuring them too
Start
1. First Download Android SDK. Roughly about 70 MB
2. There may be any compressed zip file or exe file
If zip file, then extract it to C:\android-sdk
If exe file then double click on it and install it in C:\ Drive(or any other drive you want)
3. Now to get adb and other tools, you need to download 'Platform Tools'
To download them, go to the android-sdk folder and double click on SDK Manager
It will ask you which package to download? However, it is your choice which package to Download, but here, we will only talk about platform
Tools. So, simply tick on Platform Tools and click on install. Once you have done it. Go to the platform-tools folder in the directory where you installed android-sdk. You will find several files there like adb, fastboot, aapt, etc
4. Now, you can backup the whole folder of android-sdk to any external storage that will make you not download package
again if you want to. You can have it placed in any computer and run it as it does not require registry to work
5. Now, you are just one step away from using adb. Next step is SKIPPING SETTING ENVIRONMENT VARIABLE (If you however want to set environment variables. Click on Show Content)
We can easily append the sdk platform-tools and tools folder to your systems environmental path variable directly from command line(cmd) by simply issuing one command and performing a system reboot:
Code:
[COLOR=Black]SETX PATH "%PATH%;[/COLOR][COLOR=Indigo]SDK_Install_Path[/COLOR][COLOR=Black]\platform-tools;[/COLOR][COLOR=Indigo]SDK_Install_Path[/COLOR][COLOR=Black]\android-sdk-windows\tools" -m[/COLOR]
Just replace the "SDK_Install_Path" in the above with the proper path of your SDK installation. Example: C:\android-sdk-windows
(Thanks to WugFresh for telling me :victory
Many guides on internet say that it is to be done for making it easy for users and if you have some basic knowledge of Command Prompt,
you will know that to execute any application with command prompt, you first need to change the directory to the one where application is
placed. And to skip changing the directories every time you open CMD, you need to put that application is environment variable. However, we will not do so.
6. Type cmd in the search bar. Copy cmd.exe from there. Go to the directory where you have installed android-sdk. Go to platform-tools folder. Paste cmd there, right click on it and in the settings, select Run as Administrator.
7. You are done. Now what to do in it?
ADB Commands
Type adb in command prompt. And several commands will show up on your screen. It is very difficult to analyse these all commands, so we will only talk about most used and important commands
Connect your device via USB cable
And open the CMD in platform-tools folder(Make a shortcut of it on desktop). And type the suitable commands
Code:
adb devices
Will show the list of devices attached to the PC andtheir serial numbers. If this shows up correctly on your PC, then it means that everything is fine for continuing.
Logcat
Code:
adb logcat
It will display the real time log of your device
Best time to do it is when your device boots up
Now, many users ask me how to copy the logcat and upload it from CMD
There are several methods:-
1. Right click on the Title Bar of Command Prompt. Hover the cursor over edit and select mark. Select all the things you want to copy and then click enter. All the things will be copied to clipboard.
2. This is the correct way of getting logcat saved.
Code:
adb logcat > logcat.txt
This command will create a logcat.txt document in platform-tools folder with the complete logcat of the device. Ofcourse you can type any name instead of logcat.txt
3. I prefer taking logcat this way as it neatly compiles logs of different time
Code:
adb logcat -v long > logcat.txt
This is a very nice way to get logcat.
Installing Apps
Code:
adb install %PATH OF APK%
This will install an app on your Android
For example, if my app AreeB.apk is in G:\ drive (G:\AreeB.apk)
Then I will type
Code:
adb install G:\AreeB.apk
Be sure your apk is not in a folder that has space in its name, else the command will break at space bar.
For eg:-
G:\Program Files\AreeB.apk
Note:
If you have spaces in path of apk, you can execute the command without breakage if you include the path inside quotes. (Thanks to etcman)
Eg:-
Code:
adb install "G:\Program Files\AreeB.apk"
Mounting
However, I never found any problem in tweaking with system files with adb, but some users said that they couldn't do it, so the problem was that their system partition was mounted as Read Only(R/O)
So, it is necessary now to tell how to mount system partition as Read Write(R/W)
Code:
adb remount
It is easiest way to do so, if it does not work then
There is another method that we will discuss in ADB Shell commands section
Pushing and Pulling
For pushing,
Type
Code:
adb push %PATH TO BE PUSHED% %PATH WHERE TO BE PUSHED%
Suppose I have an app named SystemUI.apk(PATH = G:\SystemUI.apk) which I want to push in /system/app/ on my android(or in other words, install an app as a system app). Then I would type
Code:
adb push G:\SystemUI.apk /system/app/
More examples
G:\Dance.txt file to be pushed in Dance folder in sdcard
Code:
adb push G:\Dance.txt /sdcard/Dance/
OR
Code:
adb push G:\Dance.txt /mnt/sdcard/Dance/
G:\Movies folder to be transferred in SDCARD in Videos Folder
Code:
adb push G:\Movies /sdcard/Videos/
G:\system\framework\framework-res.apk to be pushed in /system/framework/
Code:
adb push G:\system\framework\framework-res.apk /system/framework/
For pulling,
push command replaces with pull and paths are swapped​
Code:
adb pull %PATH TO BE PULLED FROM% %PATH TO PLACE PULLED FILE%
Example,
All system apps are to be pulled to G:\ROM\system\app
Code:
adb pull /system/app G:\ROM\system\app\
build.prop to be extracted to desktop
Code:
adb pull /system/build.prop C:\Users\Areeb\Desktop\
However, if a folder is in platform-tools folder, you don't need to type full path
Suppose if I type
Code:
adb pull /system/ system
Then a folder named system will be created inside platform-tools with all the files in system in it
If a file is in platform-tools folder, then also no need to type full path
For example,
There is an app name DeskClock.apk in this folder then, to push it to /system/app, type
Code:
adb push DeskClock.apk /system/app/
ADB Shell Commands
This mode of adb allows you to execute linux shell commands from your PC
These commands can aldo be executed through the mobile using Terminal Emulator
To initiate shell mode
Type
Code:
adb shell
You will get an prompt like this
sh-3.2#
Now you are in shell mode
adb commands won't work here and a new set of commands will work here. But we will only go in a little detail here.
Assuming you are in adb shell mode, I will only type commands that will work on shell. Note:- These commands won't work if you type them alone on cmd. But, these command will directly work on your mobile's Terminal Emulator
As these commands can also work on mobile, I am going to tell you a way of taking logcat on mobile
Type
Code:
logcat
You will see log of your device
To save this
Type
Code:
logcat > /sdcard/log.txt
A file named log.txt will be generated in sdcard
Uninstalling Applications
Code:
cd /data/app
This will change the directory to /data/app
Code:
ls
This will show the list of files in there
Suppose, there is an app named com.opera.browser (Opera Mobile) you want to uninstall it
Type
Code:
rm -r com.opera.browser
This will uninstall the app
Mounting Command:-
Code:
mount -o rw,remount /dev/block/mtdblock3 /system
Miscellanous commands:-
su: Initiates root request
du: Shows file foldrs and size
date: Shows todays date
ls: Shows list of directory
cd: Changes working directory
rm: Removes the file
logcat: Displays logcat
mount: Mounts the partition
busybox: Busybox Applets

[How-To] Starting ADB once installed

Depending on what windows version you are, for windows 7 you have to right click on an open spot on the desktop
and go to properties>advanced> Environment Variables, but for windows 8 you have go into control panel>system>Advanced setting > Environment Variables= Add new,
then the name should be ADB, and the path should be(go into the folder C:\Android\android-sdk\platform-tools,
click in the address bar of the folder and right-click to copy the address and paste that) and press ok ok ok.
Now open cmd(command prompt) and it should say C:\USER\(NAME OF YOUR COMPUTER) then after that you type: cd C:\Android\android-sdk\platform-tools (or whatever the file path is that you copied earlier, but "cd" before it tells your computer that is reading that file path as a virtual CD) now press enter. now type: "adb.exe" minus the quotation marks, this will start ADB. Now you can type whatever anyone has told you to type. Good Luck.
Please correct me if I am wrong and message me for clarification.

CD does not mean read as CD. It literally translates to Change Directory
Also if you add to path there is no reason to CD to the directory. That's the whole point of adding to path variables.
