I am following Google's instructions
to build Android on Ubuntu 12.04.
Somewhere on https://source.android.com/source/building-devices.html it says
If you don't already have those tools, fastboot and adb can be built
with the regular build system. Follow the instructions on the page
about Building and Running, and replace the main make command with
$ make fastboot adb
After using that command, the compile seems to complete fine. I then found an adb binary at
<path>/out/target/product/generic/system/bin/adb
However, when I try to use that I get an "cannot execute binary file" error.
Could it be that it was compiled for the wrong architecture? Do I need to configure something (e.g., with lunch) before the "make fastboot adb"?
Found the solution myself. I was looking at the wrong binary. The right one was at
<path>/out/host/linux-x86/obj/EXECUTABLES/adb_intermediates/adb
Now
adb devices
produces a list of devices (with one entry for the phone).

I am running android emulator in ubuntu-19.10 and I have attempted following solutions with no results,
Link-1
Link-2
Link-3
Error,
1:10 PM Emulator: pulseaudio: pa_context_connect() failed
1:10 PM Emulator: pulseaudio: Reason: Connection refused
1:10 PM Emulator: pulseaudio: Failed to initialize PA contextaudio: Could not init `pa' audio driver
Some notes on solution I tried,
When trying Link-1 i don't see "Qemu-system" in settings. Also created many different versions of AVDs but does seem to work.
After trying Link-2 pulseaudio -D command errors out.
I have also tried Link-3 which looks like widely suggested solution in multiple blog posts. But still I find the same error on emulator startup. I would like to note that I am not smart enough understand this solution.
Thanks in advance for helping out.
Same problem in Ubuntu 20.04, with Android Studio installed from Ubuntu Software. Tried everything (paprefs, this), nothing worked. Uninstall Android Studio Snap and reinstall from tar package downloaded from Android Studio website, works perfect.
I was having a similar issue on Ubuntu 20.04 but I fixed it by uninstalling the store version of Android Studio and following the installation instructions on the Official Android Studio website here: https://developer.android.com/studio/install
If you are running a 64-bit version of Ubuntu, you need to install some 32-bit libraries with the following command:
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
lib32z1 libbz2-1.0:i386
To install Android Studio on Linux, proceed as follows:
Unpack the .zip file you downloaded to an appropriate location for your applications, such as within /usr/local/ for your user profile, or /opt/ for shared users.
If you're using a 64-bit version of Linux, make sure you first install the required libraries for 64-bit machines.
To launch Android Studio, open a terminal, navigate to the android-studio/bin/ directory, and execute studio.sh.
Select whether you want to import previous Android Studio settings or not, then click OK.
The Android Studio Setup Wizard guides you through the rest of the setup, which includes downloading Android SDK components that are required for development.
I had the same issue, runing Intellij on Ubuntu 20.04. I solved it by adapting a solution from this link
I run this:
sudo ln -s /run/user/1000/pulse/native /run/user/1000/snap.intellij-idea-community/pulse
If you're using Android studio, just try to find "snap.intellij-idea-community" will be named differently, referring to your android studio installation.
On Ubuntu, is possible open the emulator with terminal and change the sound in System Preferences. Works with the instant version of Android Studio. It works with the snap version of Android Studio.
First is needed to add the emulator command to the PATH.
This can be done by editing .bashrc or .zshrc. Preferably these lines should be placed at the end of the file.
export ANDROID_SDK_PATH=$HOME/Android/Sdk
export ANDROID_NDK_PATH=$HOME/Android/Sdk/ndk
export PATH="$PATH:$HOME/Android/Sdk/platform-tools"
export PATH="$PATH:$HOME/Android/Sdk/emulator"
The PATH variable needs to be reloaded. This can be done manually, as shown below, or simply by opening another terminal:
source ~/.bashrc
# OR
source ~/.zshrc
Another way is to add adb and android-sdk-platform-tools-common packages to have the emulator command available. Package names may vary depending on the Ubuntu version.
After that, the emulator command can be used to list available emulators:
emulator -list-avds
Example of output:
Pixel_4_API_30
Pixel_C_API_30
Then can be opened one of the available emulators:
emulator #Pixel_4_API_30
Finally, the emulator probably will appear at the System Preferences:
If this is a Snap it's got strict requirements as far as i/o; that said, if the requirements are similar to those of running Androidx86 using Vbox on Debian (I realize Qemu is a different environment, however, this may be of use for both Jbaba as well as future reference. Step one: make sure that you belong to the group Qemu (or the equivalent for Ubuntu/Snap?). Step two: make sure you belong to the group pulseaudio. Step three: make sure that Qemu is explicitly permitted to access whatever your audio output device is and that it's the device that pulseaudio is configured to output to. There should be a fairly intuitive way of seeing this using Qemu (it's been awhile, so I am not able to tell you where to find it). As for pulseaudio; its GUI will show you.
I got crazy while trying to solve this issue but finally, it was solved. I figured out that we have to enable multiple simultaneous audio outputs in order to hear both sounds the emulator and the OS.
The solution is by installing paprefs small app as the following.
1- Install it:
$ sudo apt install paprefs
2- Open it:
$ paprefs
3- Go to the last tab Simultaneous Output and click on the only option there in order to enable the Simultaneous Output.
4- Restart it:
$ pulseaudio -k
5- If it fails then you have to restart the daemon
$ pulseaudio -D
6- Almost finished, go to the system settings and navigate to Sounds options and change the output sounds to the newly added one as below.
OS : Ubuntu 20.04.
Android studio (snap).
I tried all the methods, none worked for me.
By installing these libs, the sound works now.
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1 libbz2-1.0:i386
as Gigi mentionned before
I have updated android studio to Android Studio v2.3.3 (June 2017) and adb stopped showing logs when I launch app on android studio emulator
The log shows:
07/11 13:08:17: Launching app
$ adb push C:\Users\1\AndroidStudioProjects\Don'tWakeMeApp4\app\build\outputs\apk\app-debug.apk /data/local/tmp/oleksandr.ivanets.dontwakemeapp

Success
$ adb shell am start -n "oleksandr.ivanets.dontwakemeapp/oleksandr.ivanets.dontwakemeapp.MainActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
Client not ready yet..Waiting for process to come online
Connected to process 4429 on device Nexus_5X_API_26 [emulator-5554]
Click on below link
http://adbshell.com/downloads
and download the first link with name ADB Kits ( contains adb.exe and necessary .dll files).
After downloading replace these files with the ones in the path
Android/Sdk/platform-tools/
Now click on adb.exe and it will open cmd and will start the adb server.
Now it will detect the device and no problem. OOOOOllllaaaaa.....
If the Problem persists again then do the same... save the folder
somewhere.... just replace files... it will detect the device
automatically then
Preface: Although my answer focuses on Android Studio's perspective of ADB errors, I'm sure it is helpful for Windows ADB debugging in general!
#sHaRkBoY 's answer helped me look in the right direction. I used to get "Unable to detect adb version, adb output:" on Android Studio while trying to "run" the app onto the phone... and no devices showed up when phone was connected to PC.
I had tried all these (from different SO answers) but none of them worked!!!:
"Invalidate cache and restart" from File toolbar.
Turn off and turn on USB debugging on phone multiple times
Experimented with "MTP", "PTP", "Midi" and "Charging" modes to see if ADB detects something...
Checked my anti-virus software to see if adding exceptions to the adb directory works...
Installed various unnecessary C++ re-distributables
Tried a different USB cable (and USB port)
Restarted Android Studio and PC
and even uninstalled and re-installed Android studio!
The problem finally was that the platform_tools\adb.exe file downloaded by the official SDK tool manager was corrupted! So I used to get windows error code 0xc0000142 on launching adb.exe from command prompt! :(
SOLUTION:
For future readers (and victims xD) of the above ADB problem, please do the following:
Firstly, add the platform_tools\ directory into the system path environment variable.
Go ahead and replace the following 3 files in your platform_tools (C:\Users\{YourAccount}\AppData\Local\Android\Sdk\platform-tools) directory. (Please backup the same folder before, just in case.)
ADB kit (internal version number: 32)
Note: Please prefer this ADB kit (exe and dll files), compared to #sHaRkBoY 's ADB kit (2.0.0.0), since it has an updated version of AdbWinUsbApi.dll (2.0.0.1), where a race condition issue has been fixed!
I hope my answer saves your from the traumatic experience I went through while troubleshooting magical ADB for an entire day! :)
I have a program that I would like to install on an android phone (x86). The program can be installed on a Linux PC. The procedure of installing the program on the PC is:
$./configure
$make
$make install
Now I would like to do the above through android ADB so I can install it on the phone. What are the utilities needed? (I cannot find "make" in busybox http://www.busybox.net/live_bbox/live_bbox.html)
Building your program directly on the phone probably isn't going to be practical. The number of dependencies that make will wind up invoking during the build process will be huge, and either not exist or not work well on the device itself.
It would be better to look at cross-compiling, where you use a different system to build a binary that is suitable for your device.
It wouldn't be possible to provide more specific info without more detail, but be warned: you're probably in for a big project.
Maybe start here? http://forum.xda-developers.com/showthread.php?t=2723240
I'm using Terminal-IDE as my development environment. (Google code site here.)
I'm running Terminal-IDE v 2.02 - the very latest. My Android versions are:
Android 4.0.3
Software version 2.14.531.3 71ORD
(the rest aren't likely pertinent, but more on request)
I'm in a suitable development directory with a simple enough c source code file ready and run 'make'.
I have never yet gotten any compilation to work successfully. Most likely, there's a version mis-match with regard to what executable is available versus what the software is looking for.
Here's the command and error message:
terminal-gcc -c -Wall -I/data/data/com.spartacusrex.spartacuside/files/local/include tester.c -o tester.o
/data/data/com.spartacusrex.spartacuside/files/system/bin/terminal-gcc[43]: arm-eabi-gcc: not found
make: *** [tester.o] Error 127
Snafu, of course. I'm not at all sure how to find out what the right compiler file name(s) should be because, on this non-rooted phone, I don't have permissions to hunt through the PATH and find the actual executables.
It may also be that PATH is set wrong. All input appreciated.
...I'm not sure what's supposed to happen, but I found in the Terminal-IDE directory tree the file:
$IDESYSTEM/android-gcc-4.4.0.tar.gz
I also found that terminal-gcc is a bash script. Looking inside it seemed to say that a gcc tree should exist in "$HOME", which is the installation directory. So, I unzipped, then un-tarred the file identified above and put the resulting directory tree as a top-level subdirectory.
Well well, what do you know? Success.
I went a little further and created soft links to the actual compiler in ~/bin for both gcc and just cc, and suddenly all my previously created "Makefile" scripts used in other projects I wanted to move over started working perfectly.
Apparently, even though I thought I'd done it right, I overlooked running this script:
./system/bin/install_gcc
It extracts the tar, like I did, but does not create the links you may need.
Hey, if you're glad I got here before you, give it a thumbs up!
A credit goes to #Richard T for his enthusiasm regarding Terminal IDE. The answer is intended to enumerate the steps needed for running a C code.
To run a C code
Run Terminal IDE and extract the gcc package by executing
install_gcc
Create a directory for your projects within the Terminal IDE directory tree. Then in the directory create a source .c file with some code (filename.c here). Compile it
terminal-gcc -c filename.c
Create the executable file
terminal-gcc filename.o -o filename.out
Run the output file
./filename.out
If you'd like to use the PC (laptop) keyboard you can telnet Terminal IDE.
To Telnet Terminal IDE
From Terminal IDE start the telnetd deamon by executing
telnetd
Connect the Android device to the PC (laptop) and type
adb forward tcp:[port] tcp:8080
telnet 127.0.0.1 [port]
P.S. Telnet's default port is 23.
Update
After doing some more experiments, I have to reformulate my question completely as I was fooled by my terminal. It just didn't showed the error message when I issued sudo ./adb.
If I cd into the ANDOID_SDK/platform-tools directory and run ./adb, I get:
command not found: ./adb
Here the output ls -l adb in the same directory:
-rwxrwxr-x 1 myuser myuser 159620 2011-12-20 19:30 adb
Running which adb gives me:
./adb
The same happens for all other binary executable files in that directory like aapt, aidl, dexdump, etc.
I could just imagine that this has something to do with me trying to run it on a 64bit Ubuntu, but the ELF header or something similar not being recognised. However, the android tool in ANDOID_SDK/tools is running fine (besides failing to execute adb after downloading new packages).
Really strange...
Original question
I downloaded the latest Android SDK. If I try running adb as an ordinary user, I get "command not found". I must run it as "sudo ./adb" and it works. Why is that and how do I fix it? I'm running Ubuntu 64 11.10.
I used the SDK on older Ubuntu versions and there, I could run it as ordinary user without problems. Any ideas?
I found the solution. I investigated again if I really got ia32-libs installed. On a first glance, it looked fine in aptitude. However, on a second glance I noticed that the ia32-libs package was installed, but not all dependencies. I was not able to resolve that with aptitude, but instead I had to remove ia32-libs with KDE package manager and install it again. Now, all missing 88 dependencies were installed, too. adb is now working fine.
I'm not 100% sure why aptitude failed here, but I suspect that it is suffering from this bug on my installation, too: https://bugs.launchpad.net/ubuntu/+source/aptitude/+bug/831768 I also have duplicate entries in aptitude for all entries.
Add platform-tools to environmental variable,for that
Append the following line to last of the /home/yourUserName/.bashrc file in your home folder..
export PATH="your/path/android-sdk-linux/platform-tools/:${PATH}"
Run 'chown' on the android sdk folder to make your user account the owner of the folder. It sounds like it's owned by the root user at the moment. I can't remember the syntax, but there'll be plenty of examples online.
