KDE Software on Android

Android is currently the mobile platform regarding market share and number of provided applications. Hence, it is a platform very well suited to increase the availability and usage of applications by the KDE community.

Getting Applications

Stable releases for our Android apps are available on Google Play and F-Droid.

Nightly test builds can be found in the Nightly F-Droid repo.

Build Environment

There are different ways to setup a build environment:

Ready-to-Build Docker Container with Craft - This is the most convenient way to setup a system. It also brings the advantage to have a clear separation between your Linux build system and your cross-compile system; in particularly when you require several cross-compiled libraries for your application.
Setup your Build Environment Manually - This tutorial for setting up the cross-compiling environment requires considerably more time and brings the disadvantage to make no clear separation between your system and the cross-compile environment.
DEPRECATED Use Ready-to-Build Docker Container with android tooling - This works very similar to using Craft since it uses a docker environment too. However the tooling is now deprecated and no longer supported. You should use Craft in a container instead.

You can also get the binaries from binary-factory.kde.org. Here's some explanation about how it works:

Building

Example: Building Marble

cd /opt/android
git clone kde:marble
mkdir marble/build
cd marble/build
cmake -DCMAKE_TOOLCHAIN_FILE=/PATH/TO/ECM/toolchain/Android.cmake -DECM_ADDITIONAL_FIND_ROOT_PATH=${Qt5_android} -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=../export  ..
make install/strip

Note:

/PATH/TO/ECM/toolchain/Android.cmake must be replaced with the actual path to toolchain/Android.cmake, if using the docker image it probably is at /opt/android/kde/install/share/ECM/toolchain/Android.cmake
make install/strip strips build symbols from the binaries and reduces sizes considerably

Building with KDESRC-BUILD

For building the below mentioned frameworks on Android, you can use the following kdesrc-buildrc config file:

cd /opt/android
git clone git://anongit.kde.org/scratch/cordlandwehr/kdesrc-conf-android.git
mkdir -p extragear/kdesrc-build
git clone git://anongit.kde.org/kdesrc-build extragear/kdesrc-build
ln -s extragear/kdesrc-build/kdesrc-build kdesrc-build
ln -s kdesrc-conf-android/kdesrc-buildrc kdesrc-buildrc
./kdesrc-build extra-cmake-modules frameworks-android

Packaging and Deployment of APKs

See ECM Android Toolchain documentation.

KDE Frameworks 5 & Third Party Libraries

supported frameworks are listed at [1]

Third Party Libraries

libintl-lite: is required for KI18n, since BIONIC does not fully support gettext
