Within the app, I call an intent to open the Android Native Live Wallpaper Preview Screen like this:

    val intent = Intent( WallpaperManager.ACTION_CHANGE_LIVE_WALLPAPER )
    intent.putExtra( WallpaperManager.EXTRA_LIVE_WALLPAPER_COMPONENT,
        ComponentName(
            this,
            RendererWallpaperService::class.java
        )
    )
    intent.putExtra( "testtt", 123 )
    intent.flags = Intent.FLAG_ACTIVITY_CLEAR_TOP
    startActivity( intent )

And my RendererWallpaperService looks like this:

class RendererWallpaperService : WallpaperService()
{
    private var inputSensory : InputSensory?= null

    override fun onCreateEngine(): Engine
    {
        return GLESEngine()
    }

    override fun onStartCommand(intent: Intent?, flags: Int, startId: Int): Int {
        return super.onStartCommand(intent, flags, startId)
    }

    override fun onCreate() {
        super.onCreate()
    }

    internal inner class GLESEngine : GLEngine()
    {
      ....
    }
}

The problem is that I can’t access the ‘testtt‘ Extra from the intent from within the RendererWallpaperService. The getIntent method is available in Activity and since this is an WallpaperService class, there’s no such method.

I was hoping to get the intent from the onStartCommand, but it never gets called ether (but the wallpaper works).

All I want to do is to be able to distinguish if the Native Live Wallpaper Screen was called from within the app or from Android->Live Wallpapers section. I was hoping to simply pass the flag over the intent and that way I would know it was called from the app, otherwise if this flag is missing, then user opened the wallpaper through the android native UI.

How can I read the value from the intent or maybe there’s a better way to determinate if the RendererWallpaperService was ran from the app itself or from native android wallpaper selection screen? Thank you!

>Solution :

Here’s an easy hack:

private val changeWasOurs = false

class RendererWallpaperService : WallpaperService()
{
  companion object {
    fun setWasOurs() {
        changeWasOurs = true
    }
  }
}

The variable will be set to true when it was our change, and you can then skip it. Remember to set the variable to false when done with each onStartCommand.
