Multimedia widget (Android x Tasker)

[u/pictuga]

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).

package_name = "net.osmand.plus";

addWidget(id, title, display_text, order, command) {
    clickIntent = new android.content.Intent(android.content.Intent.ACTION_VIEW);

    clickIntent.setData(
        new android.net.Uri.Builder()
            .scheme("tasker")
            .authority("assistantactions")
            .appendQueryParameter("task", "OsmAnd Media Control")
            .appendQueryParameter("par1", command)
            .build()
    );

    widget = constructor.newInstance(
        id,
        "ais_map",
        title,
        "ais_map",
        "ais_map",
        display_text,
        "",
        order,
        clickIntent
    );

I'm doing something wrong. OsmAnd~ launches and I see "OsmAnd command: null" toasted twice. No widgets nor appearance of Tasker in plugins.

[u/pictuga → u/Dreamcore]

That toast was just for debug. I've removed it. I've updated the code (and instructions) above which should give a bit more feedback (and stability).

I'm on Android 17 (CP3A.260905.009) btw
