Description

This document provides information on how to start developing Status App.

Getting Started

To start developing clone the status-mobile repo in the directory of your choice.

git clone https://github.com/status-im/status-mobile.git

Then open a terminal and cd into this directory.

cd status-mobile

Then build the clojure terminal

make run-clojure

note: ⚠️ This might take a while if this is your first time.

This command installs nix and pulls in all the dependencies. Do answer with "Y" to all the prompts and press "Enter" when nix setup asks you to Acknowledge. This command builds the jsbundle and then compiles Clojure into JavaScript, watches for changes on cljs files, and hot-reloads code in the app.

wait till you see the following message :

[:mobile] Build completed. (1801 files, 52 compiled, 0 warnings, 9.52s)

Once the clojure terminal is running you need to run the appropriate command next for your platform in a separate terminal :

make run-android or make run-ios

These commands will build the app, start a metro bundler and deploy the app on your simulator OR connected device (android only). For building and deploying to connected iPhones use make run-ios-device instead of make run-ios Also check developing on a physical iOS Device.

Simulators and Devices

Android

You need to have an emulator like AVD, or Genymotion, or a real device running and visible to adb, before you run make run-android.

iOS

Running on a simulator

We highly recommend using either the iPhone 11 Pro or iPhone 13 simulator as its screen dimensions match with our design.

If you have Xcode v12.x (and above) installed in your system, you need to follow the below steps to add iPhone 13 simulator:

Open Xcode
Menu > Window > Devices and Simulators
Tap + button on bottom left
Select Device Type as iPhone 13
Leave the Simulator Name empty and tap on Create

NOTE ⚠️

Running make run-ios will target iPhone 13 by default.

If you need to run on any other simulator, you can specify the simulator type by adding the SIMULATOR flag:

make run-ios SIMULATOR="iPhone 15"

Build release

To build the app, you can simply run on of the following:

make release-android
make release-ios

For more make targets run make help.

Updating Dependencies

make nix-update-pods - iOS CocoaPods dependencies (updates ios/Podfile and ios/Podfile.loc)
make nix-update-gradle - Android Gradle/Maven dependencies (updates nix/deps/gradle/deps.json)
make nix-update-clojure - Clojure Maven dependencies (updates nix/deps/clojure/deps.json)
make nix-update-gems - Fastlane Ruby dependencies (updates fastlane/Gemfile.lock and fastlane/gemset.nix)

Manual Steps

There are a few manual steps you might want to do in order to start contributing.

Genymotion Virtualization

Optionally set up Genymotion if you don't want to use Android Virtual Device:

https://www.genymotion.com

Android Development Environment

You can also setup Android Development Environment + Simulator:

https://facebook.github.io/react-native/docs/getting-started.html

Configure GitHub Account

The optimal way of pushing to GitHub is using SSH instead of user/pass auth.

It's recommended that you add your public SSH key to your GitHub account.

Configure GPG Keys for signing commits

In order to increase security we require all commits in status-mobile repo to be signed with a GPG key.

Steps:

Additional requirements for developing on Physical iOS Device

To use a physical iPhone your device UDID must be added to provisioning profiles and your Apple account invited as Developer to Status team.

Get your UDID of your iPhone.
Request from someone with access like @cammellos or @jakubgs to

Add the UDID to development devices on Apple Developer Portal.
Invite your Apple account to be Developer in Status team.

Open XCode using the project from status-mobile/ios directory.

You might see error: Select a development team in the Signing & Capabilities editor
Select Status Research & Development GmbH as the development team.

In a new terminal execute make clean and then make xcode-clean
