There are various ways to transfer files between a computer and an Android device:
- USB cable
- special USB sticks / regular USB stick with adapter
- Arch Linux software with Android counterparts
- client or server for protocols that can be used to transfer files (eg. SSH, FTP, Samba or HTTP)
- KDE Connect ( ) – integrates your Android device with the KDE or Gnome desktop (featuring synced notifications & clipboard, multimedia control, and file/URL sharing).
- cloud synchronization clients
- AUR – cross-platform file sharing
- AUR – transfer files over wifi from your computer to your mobile device by scanning a QR code
You can install it with the AUR package.
The Android Studio Setup Wizard installs the required #SDK packages and places the SDK by default in
Android SDK packages can be installed directly from upstream using #Android Studio's SDK Manager or the sdkmanager command line tool (part of the Android SDK Tools). Some Android SDK packages are also available as AUR packages, they generally install to
The required SDK packages are:
|Android SDK Package||SDK-style path||AUR package||AUR dummy||CLI tools|
|Command-Line Tools||tools||AUR||AUR||apkanalyzer, avdmanager, lint, retrace, screenshot2, sdkmanager|
|SDK Build-Tools||build-tools;version||AUR||AUR||aapt, aapt2, aidl, apksigner, bcc_compat, d8, dexdump, dx, lld, llvm-rs-cc, mainDexClases, split-select, zipalign|
|SDK Platform-Tools||platform-tools||AUR||AUR||adb, dmtracedump, e2fsdroid, etc1tool, #fastboot, hprof-conv, make_f2fs, make_f2fs_casefold, mke2fs, sload_f2fs, sqlite3, systrace|
|SDK Platform||platforms;android-level||older versionsAUR,||AUR (unnecessary)|
- Since the Android SDK contains 32-bit binaries, you must enable the multilib repository. Otherwise you will get
error: target not found: lib32-*error messages.
- If you choose to directly install SDK packages from upstream, install the AUR packages of the AUR dummy column to pull in the required dependencies.
- If you get a
java.lang.NoClassDefFoundErrorexception when attempting to run
sdkmanager, use OpenJDK 8's JRE temporarily, by installing the package and switching the Java environment.
The Android Emulator is available as the
emulator SDK package, the AUR package, and there is also a dummy package for it: AUR.
Other SDK packages in the AUR
Making /opt/android-sdk group-writeable
The AUR packages install the SDK in
/opt/android-sdk/. This directory has root permissions, so keep in mind to run sdk manager as root. If you intend to use it as a regular user, create the android-sdk users group, add your user.
# groupadd android-sdk # gpasswd -a <user> android-sdk
Set an access control list to let members of the newly created group write into the android-sdk folder. As running sdkmanager can also create new files, set the ACL as default ACL. the X in the default group entry means "allow execution if executable by the owner (or anyone else)"
# setfacl -R -m g:android-sdk:rwx /opt/android-sdk # setfacl -d -m g:android-sdk:rwX /opt/android-sdk
Re-login or as <user> log your terminal in to the newly created group:
$ newgrp android-sdk
Android Studio is the official Android development environment based on IntelliJ IDEA. Alternatively, you can use Netbeans with the NBAndroid-V2. All are described below.
Install NBANDROID README.AUR package and follow the instructions from the
Vim / Neovim
It is possible to write
flutter applications for Android and iOS using (Neo)vim like an IDE. Install coc using a Vim plugin manager. Also install the coc-flutter extension for autocompletion (like in Android Studio) and to load the code into an Android emulator.
Marvin is a tool which helps beginners set up an Android development environment. InstallingAUR helps you set up the following things: JDK, Android SDK, IDE(s), and AVD.
Please note that these instructions are based on the official AOSP build instructions. Other Android-derived systems such as LineageOS will often require extra steps.
As of 2020/April, to build either AOSP 10 or LineageOS 17.1 you need (possibly a subset of), , , , , , , , , , , , , , , , , , , , , , , , AUR, AUR, and a TTF font installed (e.g. ). In particular, no Python2 or Java are required, as they are provided by AOSP/Lineage. The AUR metapackage provides them all for simple installation.
What follows below is only relevant to obsolete Android versions:, , , , , , , , , , , , , , , , , , , , AUR, , , , AUR.
Additionally, LineageOS requires the following packages:AUR, , , . They can be installed with the AUR metapackage.
Java Development Kit
The required JDK version depends on the Android version you are building:
- For Android 9 (Pie) and up, Java is included with the Android source and no separate installation is needed.
- For Android 7 and 8 (Nougat and Oreo), OpenJDK 8 is required, which is available with the package.
- For Android 5 and 6 (Lollipop and Marshmallow), OpenJDK 7 is required, which is available with the package.
Set JAVA_HOME to avoid this requirement and match the Arch Linux installation path. Example:
$ export JAVA_HOME=/usr/lib/jvm/java-version-openjdkThis change will be valid only for the current terminal session.
Setting up the build environment
Install the package.
Create a directory to build.
$ mkdir ~/android $ cd ~/android
The Android build process expects
python to be python2. Prepend it to the
$ mkdir bin $ ln -s /bin/python2 bin/python $ export PATH=$PWD/bin:$PATH
Alternatively, create a python2 virtual environment and activate it:
$ virtualenv2 --system-site-packages venv $ source venv/bin/activate
- This activation is only active for the current terminal session. The virtual env will be kept in the
- Passing "--system-site-packages" to virtualenv2 points your virtual environment to your installed python2.7 modules. This should give you all python modules you need for the build, assuming you have installed the required dependencies such as python2-mako.
- If during the build you still receive errors pertaining to missing python modules a quick and dirty fix might be to symlink /usr/lib/python2.7/* to ~/android/venv/lib/python2.7/ (Change ~/android to reflect your build directory if different than above).
$ ln -s /usr/lib/python2.7/* ~/android/venv/lib/python2.7/
or (assuming build directory Data/Android_Build):
$ ln -s /usr/lib/python2.7/* /Data/Android_Build/venv/lib/python2.7/
Downloading the source code
This will clone the repositories. You only need to do this the first time you build Android, or if you want to switch branches.
-jswitch that operates similarly to the one used with
make. Since it controls the number of simultaneous downloads, you should adjust the value depending on downstream network bandwidth.
- You will need to specify a branch (list of branches) to check out with the
-bswitch. If you leave the switch out, you will get the so-called master branch.
$ repo init -u https://android.googlesource.com/platform/manifest -b master $ repo sync -j4
$ repo sync -j8 -c
-c switch will only sync the branch which is specified in the manifest, which in turn is determined by the branch specified with the
-b switch, or the default branch set by the repository maintainer.
Wait a long time. Just the uncompiled source code, along with the
.git directories that are used to keep track of it, are very large. As of Android 10, at least 250 GB of free disk space is required.
$ repo sync
Building the code
This should do what you need for AOSP:
$ source build/envsetup.sh $ lunch full-eng $ make -j4
If you run lunch without arguments, it will ask what build you want to create. Use -j with a number between one and two times number of cores/threads.
The build takes a very long time.
- Make sure you have enough RAM. Android will use the
/tmpdirectory heavily. By default the size of
/tmpis half the size of your RAM. If it fills up, the build will fail. 4 GiB of RAM or more is recommended. If
/tmpis not large enough, you can increase it. Make sure you have the combined RAM and swap space to back it. Alternatively, you can get rid of the tmpfs from fstab all together.
- From the Android Building and Running guide:
- GNU make can handle parallel tasks with a
-jNargument, and it is common to use a number of tasks N that is between 1 and 2 times the number of hardware threads on the computer being used for the build. E.g. on a dual-E5520 machine (2 CPUs, 4 cores per CPU, 2 threads per core), the fastest builds are made with commands between
- GNU make can handle parallel tasks with a
Testing the build
When finished, run/test the final image(s).
Creating a flashable Image
To create an image that can be flashed it is necessary to:
make -j8 updatepackage
This will create a zip image under
out/target/product/hammerhead (hammerhead being the device name) that can be flashed.
In some cases, you want to return to the stock Android after flashing custom ROMs to your Android mobile device. For flashing instructions of your device, please use XDA forums.
Fastboot (as well as ADB) is included in the package.
- Restoring firmwares using
fastbootcan be quite tricky, but you might want to browse XDA developers forums for a stock firmware, which is mostly a
*.zipfile, but inside of it, comes with the firmware files and
flash-all.shscript. For example, Google Nexus firmwares include
flash-all.shscript or another example could be for OnePlus One - XDA thread, where you can find firmwares with included
- If you get a
no permissionserror or execution just hangs with
< waiting for any device >then you need to run
fastbootas the root user. Alternatively you can install or the AUR package AUR and reconnect your device.
Samsung devices cannot be flashed using Fastboot tool. Alternatives are Heimdall and Odin (by using Windows and VirtualBox).
To download original Samsung firmware, a platform independent script, samloader can be used.
Arch Linux (host) preparation:
- Install VirtualBox together with its extension pack and guest additions.
- Install your preferred, but compatible with Odin, Windows operating system (with VirtualBox guest additions) into a virtual hard drive using VirtualBox.
- Open VirtualBox settings of your Windows operating system, navigate to USB, then tick (or make sure it is ticked) Enable USB 2.0 (EHCI) Controller.
- At VirtualBox running Windows operating system, click in the menu bar Devices > USB Devices, then click on your Samsung mobile device from the list, which is connected to your computer via USB.
Windows (guest) preparation:
- Install Samsung drivers.
- Install Odin.
- Download required Samsung firmware (Android) for your smartphone model.
Check if configuration is working:
- Turn your device into Download mode and connect to your Linux machine.
- In virtual machine toolbar, select Devices > USB > ...Samsung... device.
- Open Odin. The white box (a big one at the bottom-left side) named Message, should print a line similar to this:
which means that your device is visible to Odin & Windows operating system and is ready to be flashed.
Use Android on GNU/Linux
There are several projects and methods which support running Android on GNU/Linux:
- Anbox: container-based software to run Android on Linux kernels
- Android-x86: a direct port of Android for the x86 architecture
Android Studio: Android Virtual Devices show 'failed to load'.
Make sure you have exported the variable
ANDROID_HOME as explained in #Android Studio.
Android Studio: 'failed to create the SD card'
If you try to run an AVD (Android Virtual Device) under x86_64 Arch and get the error above, install the multilib repository.package from the
Eclipse: During Debugging "Source not found"
Most probably the debugger wants to step into the Java code. As the source code of Android does not come with the Android SDK, this leads to an error. The best solution is to use step filters to not jump into the Java source code. Step filters are not activated by default. To activate them: Window > Preferences > Java > Debug > Step Filtering. Consider to select them all. If appropriate you can add the android.* package. See the forum post for more information: http://www.eclipsezone.com/eclipse/forums/t83338.rhtml
ValueError: unsupported pickle protocol
One fix is to issue:
$ rm ~/.repopickle_.gitconfig
If that does not work, then try this:
$ find /path/to/android-root -name .repopickle_config -delete
libGL error: failed to load driver: swrast OR AVD does not load and no error message displayed
Sometimes, beginning to load an AVD will cause an error message similar to this to be displayed, or the loading process will appear to finish but no AVD will load and no error message will be displayed.
The AVD loads an incorrect version of libstdc++, you can remove the folder libstdc++ from
~/.android-sdk/emulator/lib64 (for 64-bit) or
~/.android-sdk/emulator/lib (for 32-bit) , e.g.:
$ rm -r ~/.android-sdk/emulator/lib64/libstdc++
Note that in versions before Android Studio 3.0, this directory was in a different location:
$ rm -r ~/Android/Sdk/emulator/lib64/libstdc++
Alternatively you can set and export ANDROID_EMULATOR_USE_SYSTEM_LIBS in ~/.profile as:
Reference: Android Studio user guide
Fix for the .desktop file might be achieved by using env command, prefixing the Exec line Desktop entries#Modify environment variables
sh: glxinfo: command not found
Here is the full error:
Cannot launch AVD in emulator. Output: sh: glxinfo: command not found sh: glxinfo: command not found libGL error: unable to load driver: swrast_dri.so libGL error: failed to load driver: swrast X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 154 (GLX) Minor opcode of failed request: 24 (X_GLXCreateNewContext) Value in failed request: 0x0 Serial number of failed request: 32 Current serial number in output stream: 33 QObject::~QObject: Timers cannot be stopped from another thread
You can try to install glxinfo () but if your computer has enough power you could simply use software to render graphics. To do so, go to Tools > Android > AVD Manager, edit the AVD (click the pencil icon), then select Software - GLES 2.0 for Emulated Performance > Graphics.
Android Emulator: no keyboard input in xfwm4
In xfwm4, the vertical toolbar buttons window that is on the right of the emulator takes focus from the emulator and consumes keyboard events. (bug report)
You can use the workaround described in :
- Open the xfwm4 settings.
- Switch to the Focus tab.
- Change the Focus Model to "Focus follow mouse".
- Disable Automatically raise windows when they receive focus option below.\
