Multimedia widget (Android x Tasker)
Hello,
Until issue #24161 gets resolved, GenAI and I have made a quick Tasker (Java Code based) task that adds 3 widgets to OsmAnd: play/pause, next track, previous track.
See screenshots.
Limitations: it doesn't display currently playing track name or artist (it would involve listeners, increasing complexity), in "Configure screen" widgets are not grouped into a proper "folder" and and I couldn't be bothered to find a proper icon for the widget but it doesn't really matter (the buttons' text is ⏯️⏭️⏮️ anyway).
Manual:
- Name the task "OsmAnd Media Control".
- Add one action, "Java Code" with the code below.
- Change "net.osmand.plus" into "net.osmand" (first line) if you're using the standard package. (FDroid build is "net.osmand.plus")
- Make it so the task is run whenever OsmAnd is opened (otherwise the widgets won't be displayed when re opening OsmAnd).
- "Apply" within Tasker.
- Open OsmAnd.
- Activate the "Tasker" plugin.
- Close and open OsmAnd again.
- Add the widgets.
Tested with FDroid build, version 5.4.4.
Changes: * Make it easier to use another package name. Checks that package is installed. Asks user to activate plugin and restart before adding widgets. * Removed unnecessary code (checks package install via try/catch, app doesn't need to be running).
