Delta Chat Android Client
This is the android client for Delta Chat. For the core library and other common information, please refer to Delta Chat Core Library. For ready-to-use binaries, please go to https://delta.chat .
Build
When checking out deltachat-android, make sure also to check out the subproject deltachat-core:
-
When using Git, you can do this initially by
$ git clone --recursive https://github.com/deltachat/deltachat-androidor later bygit submodule update --init --recursive. If you do this in your home directory, this results in the folder~/deltachat-androidwhich is just fine. -
Alternatively, you can download the deltachat-android zip-file; in this case, also download the deltachat-core zip-file and place its contents to
jni/messenger-backend
Then, call ndk-build in the root directory to build the C-part;
this also builds deltachat-core. Afterwards run the project in Android Studio.
The project requires API 25.
With chance, that's it :) - if not, read on how to setup 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 called
android-studio; move this folder eg. to~/android-studio -
To launch Android Studio for the first time, open a terminal, navigate to
~/android-studio/bin, execute./studio.shand use all standard values from the wizard. -
Android Studio now ask you if you want to download 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). -
As Delta Chat uses API 25 for some reasons, click on the corresponding error message and install "Nougat 7.1.1 (API 25)" 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 Revision 14b from NDK Archives (Newer releases shall not be used currently, they are not compatible, see issues #197, #220, #248) and unzip the archive which contains a single folder called
android-ndk-r...; move this folder eg. to~/android-ndk-r... -
Export the folder path to your environment as ANDROID_NDK and add it to PATH. You can archive this eg. by adding the following lines to
.bashrc
export ANDROID_NDK=/home/bpetersen/android-ndk-r...
export PATH=$PATH:$ANDROID_NDK
The last two steps may be omitted by using the new Android Studio NDK options, however, thus far, we have not found the time to do so.
