How do i read an image file and display that image in java onto the android platform. I understand i need to use intents and activities, but i'm not sure how to do it.
Basically i want to make an app on android that reads an image file and then write/display it. This can be done using intents and activities. When the user clicks on the read button, the image file gets read, and then when the user clicks on the write button the image gets displayed.
I'm not sure how to read an image file and then to display that image onto the android platform.

I do not think it is possible to bypass the video editor. You need to go through it.
I want to make an photo gallery app, so I want something like I upload pics to a webpage and it automatically gets displayed in that app.
I don't want to edit the coding for every single image and yess I don't want "WebView" all I want is a pure native android app, that gets data (images/audios/videos) from a webpage and display it in my native android app activity.
What you need to use is a grid view, you pass an array with the links to download the image and place them in each row.
Here is an [example] (http://www.tutorialspoint.com/android/android_grid_view.htm) of how to use it.
Hope it helps

how to Capture screen in android and covert it to image
I need to capture an screenshot of screen activity, but I'm developing an external library, so I can't get current activity of the application to get the View and then flush the bitmap into canvas. Is there another way to capture a screenshot?
If you are trying to save the image from Snapchat, you need to save the Bitmap in another way.
With a rooted phone you can access the apps storage and copy the image while the app shows it.
That way the app wont notice you took a "Screenshot" :)
I am developing an Android app which reads images from external storage for image processing, creates a new folder in "pictures" on external storge and stores the processed images in it.
It takes the standard android gallery a long time or even a reboot to recognize the new folder.
Is there a way to update android gallery programmatically so my new folder gets recognized from gallery?
Trigger the mediascanner to read all the media files again. Use this piece of code :
sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://" + Environment.getExternalStorageDirectory())));
This is very inefficient though since it'll begin reading the entire SDCard for changes.
I am developing an Android application that retrieves the photographs taken by the phone camera and converts it to an alternative format. How can I retrieve the photograph that has just been shot as well as those that have been shot some time ago but still exists on the phone?
Converting the image format for existing images is just a matter of recursing file storage for images, usually the sd card but not limited to it. As far as hooking into the existing camera application you'll have to review its source to see if that is possible but you can have a service listen for the camera button and start checking for new images to convert. Android does not keep a central database of images or discriminate between "camera" and "other sources" meaning someone or something will have to decide what to convert.
You also may want to consider using the existing camera app as a library and extending it so that you are guaranteed to get the image right after its created.
