This answer is important:(taken from the link below)
"You are using MediaStore.Images.Media.EXTERNAL_CONTENT_URI which is only the external storage.For the internal there is MediaStore.Images.Media.INTERNAL_CONTENT_URI."
Loading all the images from gallery into the Application in android
Download Mobogenie Software.Then install it.Finally connect it with the Phone.Then you can move all your images stored in SDcard to mobile devices.

Currently I want to make a list like pictures and images on the server when I click on it, it will download the images to the memory device. If the image is downloaded, it will not download again and the image that is not there will be downloaded. Then I want to ask for a solution from everyone, how should I handle the download to be clean and good for performance. Or do you have an example for me to refer to? Thank you!
There are some ways to find out if your image already exists in your phone storage but the best way to find it out is by image name, compare image names before downloading.
Am developing an offline pdf reader, which will download pdf files from remote and store inside the directory(say Android->data->com.example.test) and it will be shown in my app and i can read both in online and offline.
My issue is, If I open any PDFViewers like Adobe,Radaee viewers I can see my PDF's.
How can i avoid this. I dont want to show them in other apps.
This is not intended behaviour. we can control. Am looking for solution.
Example : Whatsapp's media like albums,profilepictures will be stored in device. We can view it. If you open any external Imageviewers we cant see the Profile Pictures. We can see the Media files. But Profile pics will be hidden. I need the exact solution.
Any help will be much appreciated.
Thanks in advance.

Store the PDF on internal storage. You are presently storing the PDF on external storage.
When i develop a android app with download and caching image from internet, i see many app use MemoryLruCache or DiskLruCache to cache image after download. But i want to know why they use them, why don't use the way like: download image, then save image into sd card and after get image from sd card to show it( it is manual way).
I'm newbie in android dev. So please help me to understand it?
Thanks many many times.
well downloading a list of images from url will consume time and also fill up the user memory also....so its better to dynamically load images from url and make its cache and then preview the images from cache..
I hope you did got my point....check some example of lazy loading of image
Can someone please point me in the right direction. I have been googling for ages and I'm not getting great results.
I want my app to allow the user to download a file from the USB/SDcard. Specifically an image, which then later gets used in my app.
I can't seem to find anything, been searching for open file dialogs and nothing..
So:
1) User inserts USB device/SDCard.
2) User gets file browser dialog.
3) User finds image from USB/SDCard
4) App grabs image and stores it for later use.
Thanks :)
I think what you are looking for is how to work with external storage in Android. there is a very good tutorial from android site: http://developer.android.com/guide/topics/data/data-storage.html#filesExternal. hope this helps.
To browse for images on the SDCard this thread is very helpful:
How to pick an image from gallery (SD Card) for my app?
I would suggest using the Android Gallery interface for images as it is much easier for the user than browsing files.
Thanks for previous replies.
I want to store images that is residing in my sdcard to amazon s3 cloud. i have no idea to share the data from android to amazon, if anyone having idea, pls guide me.
Do you just want to upload the pictures then there are several apps in the market.
If you want to transfer the data programmatically then you can use the AWS SDK:
