Downloading a video from a server, but don't want to see videos in gallery

I am successfully able to download videos from sever but and I can see them in gallery. Is there any way to hide downloaded videos from gallery. We have this requirement for Unity 3D for android platform.
Thanks in advance.

You can place a blank file named .nomedia inside your download folder.
When the media scanner detects the .nomedia file, the media scanner does not scan that folder so the images and videos in that folder don't appear in the Gallery.

How to avoid saving picture at gallery or delete it automatically in Android?

The device is Samsung Galaxy III. I developed an APP to run the camera activity and capture an image. After analyzing the image, I print out some text information. Right now every captured image is saved at gallery. I don't need the image to be saved in gallery or SD card. I think either of the following two solutions will work for me, but I don't know how to program it:
avoid saving pictures to gallery.
delete the picture somewhere in the APP.
Any comments are appreciated.

Read Android Camera tutorial.

Storage - Are the images or videos your application generates intended to be only visible to your application or shared so that other applications such as Gallery or other media and social apps can use them? Do you want the pictures and videos to be available even if your application is uninstalled? Check out the Saving Media Files section to see how to implement these options.
or see this one: How to save image captured with camera in specific folder.

In the Camera intent when starting, add this:
intent.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(getTempFile(context)));

I solved my problem with following two steps:

delete all the images in that folder somewhere in the APP. How to Delete Image From SDCard in Android

When I try to push a photo onto the android emulator, I am not able to see the photo in Albums

I am new to Android and now trying to retrieve contact photo (thumb nail) from a content provider and set it onto my app. But for that as i am running on an AVD, i pushed some .png photos onto my 2.2 version. Now i tried to create a contact with the photo, but the Gallery is showing "No Media Found", hence i am stuck here.
Please help me in getting the photo visible in gallery.
Note : I am aware of the following facts :
I have restarted my AVD to force the Media Scanner to do its initial mockups.
Also i have seen the .png file through the File Explorer View of Eclipse Framework.
But strangely, I am not able to pull the file off the phone.
I have taken help of the link get the path of a Gallery Folder in Android for understanding the general view on Media Scanner.

I believe this is because the application doesn't know if there are images inside /data.
Try to put your images in:
/mnt/sdcard/Pictures

Android what's Difference between save image to Gallery and SDCARD,And How to save both?

Android how to save image in Gallery? and what's difference between save image to gallery or in sdcard Please Explain ....

You can not really save an image file into the gallery.The gallery is a native android app designed to show the image and video files on the SD card. However,when you save some media files into SD card, you can notify the mediascanservice to update the database of the gallery so that these files will be shown in gallery (by default ,not shown ).

Thumbnail location of Images/Videos in sdcard

I would like to know the location of the stored thumbnails in android sdcard. I used the adb push service to upload images and videos to the sdcard. But even after deleting few images, my application is loading the thumbnails of the deleted images which is creating problems. When I click the thumbnails, instead of the corresponding image, some other image is opening. How to delete/ re-populate the thumbnails? Also How to load the original image of the clicked thumbnail? How does android retrieve the original image corresponding to its thumbnail? what's the mapping between these two?
Thanks in advance.

Well, if you are are using system intents, like ACTION_PICK, then you probably need run media scanner ( Applications > Dev Tools > Media Scanner )
