# OpenKeychain (for Android)
|
|
|
|
OpenKeychain is an OpenPGP implementation for Android.
|
|
For a more detailed description and installation instructions go to http://www.openkeychain.org .
|
|
|
|
### Branches
|
|
* The development of OpenKeychain happens in the "master" branch.
|
|
* For every release a new branch, e.g., "3.2-fixes" is created to backport fixes from "master"
|
|
|
|
### Travis CI Build Status of master branch
|
|
|

## Development
|
|
|
|
Development mailinglist at http://groups.google.com/d/forum/openpgp-keychain-dev
|
|
|
|
### Build with Gradle
|
|
|
|
1. Clone the project from GitHub
|
|
2. Get all external submodules with ``git submodule update --init --recursive``
|
|
3. Have Android SDK "tools", "platform-tools", and "build-tools" directories in your PATH (http://developer.android.com/sdk/index.html)
|
|
4. Open the Android SDK Manager (shell command: ``android``).
|
|
Expand the Tools directory and select "Android SDK Build-tools (Version 21.1.2)".
|
|
Expand the Extras directory and install "Android Support Repository"
|
|
Select everything for the newest SDK Platform, API 22, and also API 21
|
|
5. Export ANDROID_HOME pointing to your Android SDK
|
|
6. Execute ``./gradlew build``
|
|
7. You can install the app with ``adb install -r OpenKeychain/build/outputs/apk/OpenKeychain-debug-unaligned.apk``
|
|
|
|
### Run Tests
|
|
1. Use OpenJDK instead of Oracle JDK
|
|
2. Execute ``./gradlew clean testDebug --continue``
|
|
|
|
### Run Jacoco Test Coverage
|
|
1. Use OpenJDK instead of Oracle JDK
|
|
2. Execute ``./gradlew clean testDebug jacocoTestReport``
|
|
3. Report is here: OpenKeychain/build/reports/jacoco/jacocoTestReport/html/index.html
|
|
|
|
### Development with Android Studio
|
|
|
|
We are using the newest [Android Studio](http://developer.android.com/sdk/installing/studio.html) for development. Development with Eclipse is currently not possible because we are using the new [project structure](http://developer.android.com/sdk/installing/studio-tips.html).
|
|
|
|
1. Clone the project from Github
|
|
2. Get all external submodules with ``git submodule update --init --recursive``
|
|
3. From Android Studio: File -> Import Project -> Select the cloned top folder
|
|
|
|
## Libraries
|
|
|
|
### Bouncy Castle
|
|
|
|
#### Spongy Castle
|
|
|
|
Spongy Castle is the stock Bouncy Castle libraries with a couple of small changes to make it work on Android. OpenKeychain uses a forked version with some small changes. These changes will been sent to Bouncy Castle, and Spongy Castle will be used again when they have filtered down.

## Build System
|
|
|
|
We try to make our builds as [reproducible/deterministic](https://blog.torproject.org/blog/deterministic-builds-part-one-cyberwar-and-global-compromise) as possible.
|
|
|
|
#### Update Gradle version
|
|
* Always use a fixed Android Gradle plugin version not a dynamic one, e.g. ``0.7.3`` instead of ``0.7.+`` (allows offline builds without lookups for new versions, also some minor Android plugin versions had serious issues, i.e. [0.7.2 and 0.8.1](http://tools.android.com/tech-docs/new-build-system))
|
|
* Update every build.gradle file with the new gradle version and/or gradle plugin version
|
|
* build.gradle
|
|
* OpenKeychain/build.gradle
|
|
* run ./gradlew wrapper twice to update gradle and download the new gradle jar file
|
|
* commit the corresponding [Gradle wrapper](http://www.gradle.org/docs/current/userguide/gradle_wrapper.html) to the repository (allows easy building for new contributors without the need to install the required Gradle version using a package manager)
|
|
|
|
#### Update SDK and Build Tools
|
|
* Open build.gradle and change:
|
|
```
|
|
ext {
|
|
compileSdkVersion = 21
|
|
buildToolsVersion = '21.1.2'
|
|
}
|
|
```
|
|
* Change SDK and Build Tools in git submodules "openkeychain-api-lib" and "openpgp-api-lib" manually. They should also build on their own without the ext variables.
|
|
|
|
#### Add new library
|
|
* You can add the library as a Maven dependency or as a git submodule (if patches are required) in the "extern" folder.
|
|
* If added as a Maven dependency, pin the library using [Gradle Witness](https://github.com/WhisperSystems/gradle-witness) (Do ``./gradlew -q calculateChecksums`` for Trust on First Use)
|
|
* If added as a git submodule, change the ``compileSdkVersion`` and ``buildToolsVersion`` in build.gradle to use the variables from the root project:
|
|
```
|
|
android {
|
|
compileSdkVersion rootProject.ext.compileSdkVersion
|
|
buildToolsVersion rootProject.ext.buildToolsVersion
|
|
}
|
|
```
|
|
* You can check for wrong ``compileSdkVersion`` by ``find -name build.gradle | xargs grep compileSdkVersion``
|
|
|
|
#### Slow Gradle?
|
|
|
|
* https://www.timroes.de/2013/09/12/speed-up-gradle/
|
|
* Disable Lint checking if it is enabled in build.gradle
|
|
|
|
#### Error:Configuration with name 'default' not found.
|
|
|
|
Gradle project dependencies are missing. Do a ``git submodule init && git submodule update``
|
|
|
|
#### Build on Mac OS X fails?
|
|
|
|
Try exporting JAVA_TOOL_OPTIONS="-Dfile.encoding=UTF8"
|
|
|
|
## Translations
|
|
|
|
Translations are hosted on Transifex, which is configured by ".tx/config".
|
|
|
|
1. To pull newest translations install transifex client (e.g. ``apt-get install transifex-client``)
|
|
2. Config Transifex client with "~/.transifexrc"
|
|
3. Go into root folder of git repo
|
|
4. execute ``tx pull -af --skip``
|
|
|
|
see http://help.transifex.net/features/client/index.html#user-client

|
## Coding Style
|
|
|
|
### Code
|
|
* Indentation: 4 spaces, no tabs
|
|
* Maximum line width for code and comments: 100
|
|
* Opening braces don't go on their own line
|
|
* Field names: Non-public, non-static fields start with m.
|
|
* Acronyms are words: Treat acronyms as words in names, yielding !XmlHttpRequest, getUrl(), etc.
|
|
* Fully Qualify Imports: Do *not* use wildcard-imports such as ``import foo.*;``
|
|
|
|
The full coding style can be found at http://source.android.com/source/code-style.html
|
|
|
|
