Android let app know that media was mounted/unmounted while app was destroyed

Question

Is there a way to let my app know that Media (SDCard) was mounted/unmounted while my app was turned off? I mean that my app and its services were Destroyed, not only stopped. Probably, some ways to check MediaStore checksum are available?

Goal: decide if new music files were added or deleted in device memory to refresh general playlist.

Why not check if the SDCARD is mounted by using Environment.getExternalStorageState() upon restarting your app? The value you want it to be is Environment.MEDIA_MOUNTED. You could do it async and display a message somewhere stating that an update is in progress, however...

...if it's really the callback-ish thing you need, then you'll have to have a look at what John Willis wrote about registering a BroadcastReceiver.

But better to register Intent.ACTION_MEDIA_SCANNER_FINISHED - when MediaStore is already updated – Sergii Jul 11 '12 at 08:42

thanks, its right idea, but it's better to register Intent.ACTION_MEDIA_SCANNER_FINISHED - when MediaStore is already updated – Sergii Jul 11 '12 at 08:45
I think that answer by @ninetwozero is more informative, so I've accepted it. But I put "useful answer" for your advice. Thanks again! – Sergii Jul 11 '12 at 08:57
