+# Jitsi in Element Android
+
+Native Jitsi support has been added to Element Android by the PR [#1914](https://github.com/vector-im/element-android/pull/1914). The description of the PR contains some documentation about the behaviour in each possible room configuration.
+
+Also, ensure to have a look on [the documentation from Element Web](https://github.com/vector-im/element-web/blob/develop/docs/jitsi.md)
+
+The official documentation about how to integrate the Jitsi SDK in an Android app is available here: https://jitsi.github.io/handbook/docs/dev-guide/dev-guide-android-sdk.
+
+# Native Jitsi SDK
+
+The Jitsi SDK is built by ourselves with the flag LIBRE_BUILD, to be able to be integrated on the F-Droid version of Element Android.
+
+The generated maven repository is then host in the project https://github.com/vector-im/jitsi_libre_maven
+
+## How to build the Jitsi Meet SDK
+
+### Jitsi version
+
+Update the script `./tools/jitsi/build_jisti_libs.sh` with the tag of the project `https://github.com/jitsi/jitsi-meet`.
+
+Currently we are building the version with the tag `android-sdk-2.9.3`.
+
+### Run the build script
+
+At the root of the Element Android, run the following script:
+
+```shell script
+./tools/jitsi/build_jisti_libs.sh
+```
+
+It will build the Jitsi Meet Android library and put every generated files in the folder `/tmp/jitsi`
+
+### Link with the new generated library
+
+- Update the file `./build.gradle` to use the previously created local Maven repository. Currently we have this line:
+
+```groovy
+url "https://github.com/vector-im/jitsi_libre_maven/raw/master/android-sdk-2.9.3"
+```
+
+You can uncomment and update the line starting with `// url "file://...` and comment the line starting with `url`, to test the library using the locally generated Maven repository.
+
+- Update the dependency of the WebRTC library in the file `./matrix-sdk-android/build.gradle`. Currently we have this line:
+
+```groovy
+implementation('com.facebook.react:react-native-webrtc:1.84.0-jitsi-5112273@aar')
+```
+
+- Update the dependency of the Jitsi Meet library in the file `./vector/build.gradle`. Currently we have this line:
+
+```groovy
+implementation('org.jitsi.react:jitsi-meet-sdk:2.9.3') { transitive = true }
+```
+
+- Perform a gradle sync and build the project
+- Perform test
+
+### Sanity tests
+
+In order to validate that the upgrade of the Jitsi and WebRTC dependency does not break anything, the following sanity tests have to be performed, using two devices:
+- Make 1-1 audio call (so using WebRTC)
+- Make 1-1 video call (so using WebRTC)
+- Create and join a conference call with audio only (so using Jitsi library). Leave the conference. Join it again.
+- Create and join a conference call with audio and video (so using Jitsi library) Leave the conference. Join it again.
+
+### Export the build library
+
+If all the tests are passed, you can export the generated Jitsi library to our Maven repository.
+
+- Clone the project https://github.com/vector-im/jitsi_libre_maven.
+- Create a new folder with the version name.
+- Copy every generated files form `/tmp/jitsi` to the folder you have just created.
+- Commit and push the change on https://github.com/vector-im/jitsi_libre_maven.
+- Update the file `./build.gradle` to use the previously created Maven repository. Currently we have this line:
+
+```groovy
+url "https://github.com/vector-im/jitsi_libre_maven/raw/master/android-sdk-2.9.3"
+```
+
+- Build the project and perform the sanity tests again.
+
+- Update the file `/CANGES.md` to notify about the library upgrade, and create a regular PR for project Element Android.
