# Jitsi Meet mobile apps

Jitsi Meet can also be built as a standalone mobile application for
iOS and Android.  It uses the [React Native] framework.

First make sure the [React Native dependencies] are installed.

**NOTE**:  This document assumes the app is being built on a macOS system.

**NOTE**:  The app must be built for an actual device since the simulators don't
work properly with the native plugins we require.


## iOS

1. Install some extra dependencies

  - Install ios-deploy globally (in case you want to use the React Native CLI
    to deploy the app to the device)

    ```bash
    npm install -g ios-deploy
    ```

    You may need to add ```--unsafe-perm=true``` if you are running on [Mac OS 10.11 or greater](https://github.com/phonegap/ios-deploy#os-x-1011-el-capitan-or-greater).

2. Build the app

    There are 2 ways to build the app: using the CLI or using Xcode.

    Using the CLI:

    ```bash
    react-native run-ios --device
    ```

    When the app is launched from the CLI the output can be checked with the
    following command:

    ```bash
    react-native log-ios
    ```

    Using Xcode

    - Open **ios/jitsi-meet-react.xcworkspace** in Xcode. Make sure it's the
      workspace file!

    - Select your device from the top bar and hit the "play" button.

    When the app is launched from Xcode the Debug console will show the output
    logs the application creates.


3. Other remarks

    It's likely you'll need to change the bundle ID for deploying to a device
    because the default bundle ID points to the application signed by Atlassian.

    This can be changed in the "General" tab.  Under "Identity" set
    "Bundle Identifier" to a different value, and adjust the "Team" in the
    "Signing" section to match your own.


## Android

The [React Native dependencies] page has very detailed information on how to
setup [Android Studio] and the required components for getting the necessary
build environment.  Make sure you follow it closely.

1. Building the app

    The app can be built using the CLI utility as follows:

    ```bash
    react-native run-android
    ```

    It will be launched on the connected Android device.


## Debugging

The official documentation on [debugging] is quite extensive, it is the
preferred method for debugging.

**NOTE**: When using Chrome Developer Tools for debugging the JavaScript code
is being interpreted by Chrome's V8 engine, instead of JSCore which
React Native uses.  It's important to keep this in mind due to potential
differences in supported JavaScript features.
