Building Signal
|
|
===============
|
|
|
|
Basics
|
|
------
|
|
|
|
Signal uses [Gradle](http://gradle.org) to build the project and to maintain
|
|
dependencies. However, you needn't install it yourself; the
|
|
"gradle wrapper" `gradlew`, mentioned below, will do that for you.
|
|
|
|
Building Signal
|
|
---------------
|
|
|
|
The following steps should help you (re)build Signal from the command line.
|
|
|
|
1. Checkout the Signal-Android project source with the command:
|
|
|
|
git clone https://github.com/WhisperSystems/Signal-Android.git
|
|
|
|
2. Make sure you have the [Android SDK](https://developer.android.com/sdk/index.html) installed.
|
|
3. Ensure that the following packages are installed from the Android SDK manager:
|
|
* Android SDK Build Tools
|
|
* SDK Platform (API level 22)
|
|
* Android Support Repository
|
|
* Google Repository
|
|
4. Create a local.properties file at the root of your source checkout and add an sdk.dir entry to it. For example:
|
|
|
|
sdk.dir=/Application/android-sdk-macosx
|
|
|
|
5. Execute Gradle:
|
|
|
|
./gradlew build
|
|
|
|
Visual assets
|
|
----------------------
|
|
|
|
Source assets tend to be large binary blobs, which are best stored outside of git repositories. We host ours in a [Pixelapse repository](https://www.pixelapse.com/openwhispersystems/projects/signal-android/). Some source files are SVGs that can be auto-colored and sized using a tool like [android-res-utils](https://github.com/sebkur/android-res-utils).
|
|
|
|
Sample command for generating our audio placeholder image:
|
|
|
|
```bash
|
|
pngs_from_svg.py ic_audio.svg /path/to/Signal/res/ 150 --color #000 --opacity 0.54 --suffix _light
|
|
pngs_from_svg.py ic_audio.svg /path/to/Signal/res/ 150 --color #fff --opacity 1.00 --suffix _light
|
|
```
|
|
|
|
Setting up a development environment
|
|
------------------------------------
|
|
|
|
[Android Studio](https://developer.android.com/sdk/installing/studio.html) is the recommended development environment.
|
|
|
|
1. Install Android Studio.
|
|
2. Open Android Studio. On a new installation, the Quickstart panel will appear. If you have open projects, close them using "File > Close Project" to see the Quickstart panel.
|
|
3. From the Quickstart panel, choose "Configure" then "SDK Manager".
|
|
4. In the SDK Tools tab of the SDK Manager, make sure that the "Android Support Repository" is installed, and that the latest "Android SDK build-tools" are installed. Click "OK" to return to the Quickstart panel.
|
|
5. From the Quickstart panel, choose "Checkout from Version Control" then "git".
|
|
6. Paste the URL for the Signal-Android project when prompted (https://github.com/WhisperSystems/Signal-Android.git).
|
|
7. Android studio should detect the presence of a project file and ask you whether to open it. Click "yes".
|
|
9. Default config options should be good enough.
|
|
9. Project initialisation and build should proceed.
