Riot-Android Jenkins Weblate Android Matrix room #riot-android:matrix.org Quality Gate Vulnerabilities Bugs

Riot is an Android Matrix client.

Get it on Google Play

Get it on F-Droid


Please refer to CONTRIBUTING.md if you want to contribute the Matrix on Android projects!

Build instructions

This client is a standard android studio project.

If you want to compile it in command line with gradle, go to the project directory:

Debug mode:

./gradlew assembleDebug

Release mode:

./gradlew assembleRelease

And it should build the project (you need to have the right android SDKs)

Recompile the provided aar files until we have gradle

generate olm-sdk.aar

sh build_olm_lib.sh

generate matrix-sdk.aar

sh build_matrix_sdk_lib.sh

generate the other aar files

sh build_jitsi_libs.sh

compile the matrix SDK with the Riot-android project

sh set_debug_env.sh

Make your own flavour

Let says your application is named MyRiot : You have to create your own flavour.

Modify riot-android/vector/build.gradle

In "productFlavors" section, duplicate "app" group if you plan to use FCM or "appfdroid" if don't.

for example, with FCM, it would give

    appmyriot {
        applicationId "im.myriot"
        // use the version name
        versionCode rootProject.ext.versionCodeProp
        versionName rootProject.ext.versionNameProp
        buildConfigField "boolean", "ALLOW_FCM_USE", "true"
        buildConfigField "String", "SHORT_FLAVOR_DESCRIPTION", "\"F\""
        buildConfigField "String", "FLAVOR_DESCRIPTION", "\"FDroid\""
  • if you use FCM, duplicate appImplementation at the end of this file and replace appImplementation by appmyriotImplementation.
  • if you don't, update the "if (!getGradle().getStartParameter().getTaskRequests().toString().contains("fdroid"))" to include your flavor.

Create your flavour directory

  • Copy riot-android/vector/src/app or appfroid if you use FCM or you don’t.
  • Rename it to appmyriot.
  • If you use FCM, you will need to generate your own google-services.json.

Customise your flavour

  • Open riot-android/vector/src/appmyriot/AndroidManifest.xml
  • Change the application name to myRiot with "android:label="myRiot"" and "tools:replace="label"" in the application tag.
  • Any other field can be customised by adding the resources in this directory classpath.
  • Open Android studio, select your flavour.
  • Build and run the app : you made your first Riot app.

You will need to manage your own provider because "im.vector" is already used (look at VectorContentProvider to manage it).

Customise your application settings with a custom google play link

It is possible to set some default values to Riot with some extra parameters to the google play link.

  • Use the https://developers.google.com/analytics/devguides/collection/android/v4/campaigns URL generator (at the bottom)
  • Set "Campaign Content" with the extra parameters (e.g. is=http://my__is.org%26hs=http://my_hs.org). Please notice the usage of %26 to escape the &
  • Supported extra parameters:
    • is : identity server URL
    • hs : home server URL
  • Generate the customised link
  • The application may have to be installed from the Play Store website (and not from the Play Store application) for this feature to work properly.
