Cloud music app is a very unofficial thing - remember that you don´t pay for anything, and it seems this music comes pirated from China or so.
It is not in any way an official App promoted or supported by UBports.
That said, I don´t know but for any questions you need to reach out to the app developer, which you probably can find in the Openstore details. But I don´t think anyone here will be able to help you, since we don´t know the developer at all.
Depending of your projects, but if you want to develop a "standalone" applications and Cross-platforms, i would recommend you to learn Qt QML with QtQuick Controls 2 first, so that you can test easily ( and quickly ) your app on your desktop.
Beware that ubuntu touch ships Qt 5.9.7 ( not 100% sure)
Clickable is the shortest path for a quick "hello world" on UT
@thepeter Yup it works. I believe bluetooth supports up to 7 devices at the same time. Not sure about the latest versions 🙂
Been using that setup for a long time with my Nexus 7 and 5. Slimport + BT Keyboard + BT Mouse + sometimes BT earphone.
Beware with some advanced BT mouse though especially those with extra buttons like in Logitech. They might be detected as keyboard as well so OSK will be hidden even without connecting a real keyboard. And there's a current bug that even after disconnecting it, the device won't detect it so OSK will still be hidden. In the edge channel, this can be worked around by enabling the new setting to show OSK even with a physical keyboard present.
@dobey I have had transmission installed in Libertine and ran only the backend there. I think from terminal. Transmission offers a webinterface, so I could just go to http://localhost:SOMEPORTNUMBER and that gave me a reasonable touch interface (website). I had no lifecycle problems that way, I think Libertine processes are not restricted that way. It's been a long time since I did that, but I don't think any of the relevant technology has changed.
