You can put any file name in the image-provider's DATA column
("_data").As long as your image is in the image-provider, other gallery apps will see your image. If you don't add the image yourself (getContentProvider().insert(...)), then the MediaScanner will do this for you when it's run (upon remount of your SD or Phone storage). Note that using MediaStore.Images.Media.EXTERNAL_CONTENT_URI only allows for inserting/handling images on your SD-card. Any phone without an SD card (many HTC Incredibles, for example) won't run your app properly. On Jun 30, 1:18 am, Julian <[email protected]> wrote: > Thanks (belatedly) for your reply.
