@CiberSheep Thank you for sharing this code with me.
I've noticed that the problem seems to exist for this app too, as the developer uses a timer to start playback with a delay.
I applied this in my code and it seems to work. I'll now be able to add a few features to it.
Thanks again.

Here's a code snippet if it helps anyone in the future. Timer interval (1500ms) to be adapted.

    Timer {
        id: playStarter
        interval: 1500
        onTriggered: {
            musicPlayer.play()
        }
    }
    MediaPlayer {
        id: musicPlayer
    }

    function pause() {
        musicPlayer.pause();
    }

    function play() {
        if (musicPlayer.source) {
            musicPlayer.pause();
            playStarter.restart();
        }
    }

@CiberSheep Thank you. I was using mediaplayer but the problem was the same. I'll dig up the subject again and go over the code. As my request is basic, the problem is certainly in my approach and my code.
I will be back.

@arubislander the Nextcloud API does not allow you to retrieve Ampache/Subsonic identifiers from the Music application.

I've looked at the UT Tweak Tool code but I don't have the skills for it.
UTTT allows you to interrupt an app. It's functional, I won't go any further.
Thanks!

@domubpkm Great, thanks.
Already, it works when I enable this option on my app.
That's a first step.
I'll see if I can integrate the option into my app to be independent of UT Tweak Tool.

I trigger a timer in an app (qml) but it pauses when the screen is off/locked.
In apparmor, I use “keep-display-on”.

In the code, although I don't think it's normally useful :

import QtSystemInfo 5.5
    ScreenSaver {
        id: screenSaver
        screenSaverEnabled: false
    }

Do you have a solution, please?

For the UT Nextcloud Music application, I'm looking to store the connection form data (url, user, password) to avoid having to retype them regularly.
I've managed to store this data in an sqlite database. Everything's working fine.
But I'm wondering about saving the password in clear text in a local database.
Is it secure?
Do I have to hash/salt it? Knowing that I have to do the reverse afterwards, which makes the method available to anyone?
Is it possible to use a system method? And if so, do you know a piece of QML code to store and retrieve this, please?

@Tilo_HH I have the same phone but I use deezer via Waydroid. The UT-Deezer app is too unstable for me.
Streaming services are very closed, the music's industry more than it. Maybe Spotify can be used via Waydroid.
That is, an android simulated on UT that allows you to install F-Droid (via the apk on the official f-droid site) then Aurora Store (via F-Droid) then Spotify (via Aurora Store).
Aurora Store enables you to use Google Play Store.
F-droid is an open-source application store.
You can also boycott companies that don't let you use them via open-source applications. However, they don't really care, given the small market share we represent. It's then possible to look for alternatives for listening to music. Spotify/Deezer & co are not The Music.

I'm sorry I can't help you more than to suggest you use the official app via Waydroid or listen to music other than via streaming services.

@ikoz Sorry, I misspoke.
I want the audio to play when I use this.play() (via a button, for example). It works except the first time.

1. this.play(): no playback
2. this.pause() then this.play(): playback
3. Other this.play() (for another song, for example): playback

I now display the audioplayer status.
On PC, it quickly goes from 2 (loading) to 6 (buffering).
On smartphone, it stalls at 2 (loading) until I do step 2 above, when it switches to 3 (loaded).
The behavior seems different. The player seems to be stuck at 2 (Loading).

        }

Hello everyone,

Thank you for the wonderful work everyone does here!
I'm trying to fix some issues I've encountered on two apps I'm developing (Radio Nova and UT Nextcloud Music) and that are already available on the store.

The first problem is audio playback at first launch. It is currently necessary to manually click on pause then play for the audio to actually launch. It's as if the player hadn't been properly initialized.
Here's an example of Main.qml code that reproduces this problem.
I don't have any problems with clickable desktop. Unfortunately, I can't test on my smartphone other than with a build because clickable doesn't work properly (issue 447 of clickable), so I don't have the execution logs on smartphone.

The second problem, perhaps linked to the system's audio management, is that the player does not skip to the next song if the application is not in focus.
In other words, everything's fine if the app is open on the screen, but if the player is put to sleep or another application is displayed, it doesn't skip to the next audio track.
If these problems are not related, I can open another topic.

Can you help me, please?

The imported libraries are certainly too numerous, contrary to my development skills.
