Uri localUri = localContentResolver.insert(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, localContentValues);
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, localUri));
public static ContentValues getVideoContentValues(Context paramContext, File paramFile, long paramLong)
{
　　ContentValues localContentValues = new ContentValues();
　　localContentValues.put("title", paramFile.getName());
　　localContentValues.put("_display_name", paramFile.getName());
　　localContentValues.put("mime_type", "video/mp4");
　　localContentValues.put("datetaken", Long.valueOf(paramLong));
　　localContentValues.put("date_modified", Long.valueOf(paramLong));
　　localContentValues.put("date_added", Long.valueOf(paramLong));
　　localContentValues.put("_data", paramFile.getAbsolutePath());
　　localContentValues.put("_size", Long.valueOf(paramFile.length()));
