Delta Chat Android Client
This is the Android client for Delta Chat.
It is available on F-Droid and
the Google Play Store.
The APK can also be downloaded from GitHub
(only for experienced users).
For the core library and other common info, please refer to the
Delta Chat Core Library.
Build
When checking out deltachat-android, make sure also to check out the
subproject deltachat-core-rust:
- When using Git, you can do this initially by
$ git clone --recursive https://github.com/deltachat/deltachat-android
or later bygit submodule update --init --recursive. If you do this in your
home directory, this results in the folder~/deltachat-androidwhich is just fine.
Then, open ndk-make.sh in an editor and follow the instructions
to set up a rust build environment. This is needed only once.
After that, call ./ndk-make.sh in the root directory to build core-rust.
Afterwards run the project in Android Studio. The project requires API 25.
With chance, that's it :) - if not, read on how to set up a proper development
environment.
Install Development Environment
-
Some libs required by Android Studio may be missing on 64 bit Linux machines
Source], so for Ubuntu execute
$ sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1 libbz2-1.0:i386
and for Fedora execute
$ sudo yum install zlib.i686 ncurses-libs.i686 bzip2-libs.i686. -
Download Android Studio from https://developer.android.com (android-studio-ide-...-linux.zip)
and unpack the archive which contains a single folder calledandroid-studio;
move this folder e.g. to~/android-studio. -
To launch Android Studio for the first time, open a terminal, navigate to
~/android-studio/bin, execute./studio.shand use all the standard values
from the wizard. -
Android Studio now asks you if you want to open an existing project;
choose~/deltachat-androidas created in the "Build" chapter (Android Studio starts to
build the project, however, there are some steps missing before this will
succeed). -
If components are missing, click on the corresponding error
message and install eg. required SDKs and the "Build-Tools" (you should
also find the option at "Tools / Android / SDK Manager / SDK Platforms").
Now the build should succeed - but the app still misses the native part. -
Download Android NDK from
NDK Archives
and extract the archive containing a single folder
calledandroid-ndk-r…; move this folder e.g. to~/android-ndk-r…. -
Export the folder path to your environment as
ANDROID_NDKand add it toPATH.
You can achieve this e.g. by adding the following lines to.bashrc
export ANDROID_NDK=/home/USERNAME/android-ndk-r…
export PATH=$PATH:$ANDROID_NDK.
