I have a mass storage device that when I write on a sector, it does something on this sector and write on it again. I wrote a program in Android that writes on mass storage device's sectors, but when sector was changed, the value in the file does not change. I want to refresh my mass storage device so that changes are visible. I am sorry about my bad grammar, I am Iranian and I can't speak English well

I have had same issue.. Please try this..

sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,
Uri.parse("file://" + Environment.getExternalStorageDirectory())));

or

sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://" + Environment.getExternalStorageDirectory())));

or you can refer this link also..

SD card files updated programmatically are not updated in windows explorer

Hope this might help you..

  • Have you try this code?? MediaScannerConnection.scanFile (this, new String[] {file.toString()}, null, null); Add this line before sendBroadcast method.. it might work.. – Raghav Mehta Feb 03 '16 at 05:46
