How to build the app on Ubuntu 18.04

Clone repository and select branch fairchat-master (or mergeWith1.n.n)

$ git clone git@git.fairkom.net:chat/fairchat.ReactNative.git
$ cd fairchat.ReactNative
$ git checkout fairchat-master

(or checkout the branch with latest merge from upstream Rocket.Chat-ReactNative)

Install OpenJDK 8 (version 11 may have problems as some libraries are deprecated like java.se.ee) and check if both java and javac are the same version 8
Install Android Studio custom set-up with checkboxes on for:

Android SDK
Android SDK Platform
Android Virtual Device

```bash
export ANDROID_HOME=~/Software/AndroidSDK
```

Install dependencies from working dir and be sure to have a stable node version (10.13 works fine, not 8, 12 is not yet supported by realm package as of Oct 2019)

$ sudo apt install nodejs npm curl
$ sudo npm cache clean -f
$ sudo npm install -g n
$ sudo n 10
$ sudo npm install -g yarn
$ sudo npm install -g react-native-cli 
$ sudo chown -R $USER:$(id -gn $USER) /home/ras/.config 
$ npm install --save realm
$ yarn global add react-native-cli
$ yarn config set cache-folder /media/someGBstorage/yarn/cache/
$ yarn

forward 8081 ports if device is connected via USB (or change dev settings in device to connect via same WIFI to port 8081 on pc)
```
$ adb reverse tcp:8081 tcp:8081
```
Run Metro handler on port 8081 in separate terminal window in same working dir
```
$ npm start
```

You might need to restart it after major commits with new dependencies.

Build and run application

$ react-native run-ios

$ react-native run-android

Changing branch or merging commits requires full rebuild (react-native should not require this ...)

   $ git checkout newfeature
   $ yarn 
   $ react-native run-android

If you want to rebuild the storybook

yarn add --dev jest
yarn global add jest
jest --updateSnapshot

Remove checks with pre-commit (syntax checks)

rm -f .git/hooks/*

For a release build, install keystore https://git.fairkom.net/chat/fairchat.ReactNative/issues/23 and run

 $ react-native run-android --variant=release
 ```
