AI 2 : RCS and Ubuntu touch : little hope ! RCS on Ubuntu Touch: Technical Feasibility and Possible Solutions Your Question Can the RCS protocol be easily ported to the alternative ROM Ubuntu Touch based on Ubuntu 24.04 or 26.04? Are there technical solutions? Direct Answer Yes, Ubuntu Touch presents favorable technical opportunities for porting RCS, but no solution is currently officially operational. Favorable Architecture of Ubuntu Touch Unlike AOSP-based ROMs, Ubuntu Touch relies on a Linux-native architecture with Qt/QML technologies for its applications. The official messaging app uses a history-service backend and currently only supports SMS/MMS, but its modular design offers the flexibility necessary to integrate an RCS stack without the constraints imposed by the Google Play Services ecosystem. Three Identified Technical Paths 1. Native Qt/QML RCS Client This approach would allow directly implementing GSMA specifications within Ubuntu Touch's open code. However, this would likely require GSMA certification and potentially direct agreements with telecom operators to access their RCS servers. 2. Waydroid as Android Container Ubuntu Touch already includes experimental support for Waydroid, allowing Google Messages to run isolated in an Android container within the Linux system. This would provide full RCS functionality while maintaining the de-googled base system, although this maintains some indirect dependency on Google services. 3. Porting Third-Party Applications via Click/OpenStore Ubuntu Touch's Click package system already allows deployment of complex applications like Delta Chat. A compatible RCS client could therefore theoretically be ported to this ecosystem without resorting to proprietary frameworks. Prerequisite Conditions Required Regardless of the chosen approach, several conditions remain essential: Access your operator's specific RCS servers as they vary by region Obtain GSMA certification if developing an independent client rather than using Google's Manage history integration with the existing history-service backend to ensure data consistency between SMS, MMS, and RCS Current Status and Outlook As of today, no official RCS implementation is available on Ubuntu Touch. These proposals are based on technical discussions documented within the UBports community which identified these possibilities. True viability will depend on mobilizing active contributors with the necessary knowledge in telecommunications protocols and Qt/QML development. Without dedicated community investment, these technical paths will remain theoretical despite their demonstrated architectural feasibility.

@iceman198 The clickable software will output a .click "Clickable" From what you posted you have installed the clickable software on your Ubuntu machine as a Snap package. I have it installed from the ubuntu apt repo. If the software is now working for your needs then it's nothing to worry about.

pparent said: I've noticed a bug that is a bit problematic: I cannot allow a QML5 app to have access to the microphone. For example if I install the Recorder app, without previous install, I cannot record anything, because I cannot allow it to access to the microphone, no authorization dialog shows up. I guess the same may apply to position permission. After a reboot the problem seems gone. I don't really understand because I had tried with several different apps and got the same problem.

@gpatel-fr I've posted a new version of Touch Piano, that now runs on 24.04-2.x, you can retry your tests with it if you want. My guess is that at least part of the packets included into the bundle could be removed to use the system libraries on 24.04-2.0, but I will wait for official Qt6 app guidelines before doing that.
