I set video as live wallpaper and it work fine. But when i change that video by replacing the path. In Preview it show the video changed but after click on "SET WALLPAPER" the previous one is not changed. How can i change the current video with new one while my live wallpaper is in running on phone. source code for my wallpaper is below:
class VideoLiveWallpaperService : WallpaperService() {
val PREFS_FILENAME = "com.billionaire.wallpaper.prefs"
val wall = "wall"
var prefs: SharedPreferences? = null
override fun onCreateEngine(): WallpaperService.Engine {
return VideoEngine()
}
internal inner class VideoEngine : WallpaperService.Engine() {
private val TAG = javaClass.simpleName
private val mediaPlayer: MediaPlayer
init {
Log.i(TAG, "( VideoEngine )")
// get pref for wallpapers
prefs = baseContext.getSharedPreferences(PREFS_FILENAME, 0)
val wall_path = prefs!!.getString(wall, "null")
val f = File(Environment.getExternalStorageDirectory().toString() + "/"+wall_path)
// System.out.println("Path >>>>>>>>>????? " + Environment.getExternalStorageDirectory().absolutePath+"ibad.mov");
if (wall_path.equals("null") && !f.isDirectory) {
mediaPlayer = MediaPlayer.create(baseContext,R.raw.test)
mediaPlayer.isLooping = true
} else{
val uri = Uri.parse(Environment.getExternalStorageDirectory().toString() + "/"+wall_path)
mediaPlayer = MediaPlayer()
mediaPlayer.setDataSource(baseContext, uri)
mediaPlayer.prepare()
mediaPlayer.isLooping = true
}
}
override fun onSurfaceCreated(holder: SurfaceHolder) {
Log.i(TAG, ":::::::::: onSurfaceCreated")
mediaPlayer.setSurface(holder.surface)
mediaPlayer.start()
}
override fun onSurfaceDestroyed(holder: SurfaceHolder) {
Log.i(TAG, "( :::::::: INativeWallpaperEngine ): onSurfaceDestroyed")
playheadTime = mediaPlayer.currentPosition
mediaPlayer.reset()
mediaPlayer.release()
}
}
companion object {
protected var playheadTime = 0
}
}
When i change the link in preference then i call live wallpaper by following code:
try
{
val intent = Intent(WallpaperManager.ACTION_CHANGE_LIVE_WALLPAPER)
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
intent.putExtra(WallpaperManager.EXTRA_LIVE_WALLPAPER_COMPONENT,
ComponentName(this@AnimattedViewpagerActivity, VideoLiveWallpaperService::class.java))
startActivity(intent)
}
catch (e:Exception) {
val intent = Intent()
intent.setAction(WallpaperManager.ACTION_LIVE_WALLPAPER_CHOOSER)
startActivity(intent)
}
the above code open Preview mode of live wallpaper. in this mode the wallpaper changed but after i click on "Set Wallpaper" button in this Preview, it can't change that previous video. Please help me.
