I am developing an app which captures an image and stores it in gallery with a name returned by the currentTimeInMillis() method of java.lang package. For better recognition I want to rename those images but i found there is no rename option in the gallery.
Can anybody is there any issue behind not giving this option.
The gallery application scans the filesystem and shows the pictures as they appear. If you need to change the filename, you can do this with the File.renameTo() method.

My Flutter app will be used to capture image then save to device. I want to remove all images in my device at a preset time. Is there a way to do that?
I think it not because if an app can delete all the images in device so it will not safe to use that app but I still hope it have because it needs for my app.
Things are changing with the recent releases of Android. Access to file system is not going to be same. but you are going to save the captured image in a folder where you have write access, there you can delete all the pictures without a problem

Thank you For Your Help
Unfortunately, this is impossible. Your app can launch the Camera with INTENT_ACTION_STILL_IMAGE_CAMERA intent, but it has no control over the way the Camera app will work.
Luckily, when (and if) the Camera app is closed and control is back to your app, you can scan the MediaStore for new images, wherever they are on the device. Your app should have r/w access to these images, and then it can simply move all of them (or some of them) to alternative directory.
My app saves images to a subfolder of the DCIM folder on the SD-card in the phone.
I do not wish these images to be shown in the androids gallery app.
How can I achive this?
add an empty file called .nomedia in the directory where you store the images
To hide your image file add . to file name for example sdcard/DEIM/yourapp/.yourimage.jpg
this will hide an Image.
If you want to hide one folder add . to the folder name sdcard/DEIM/.yourapp/image1.jpg
I found this solution: Stop saving photos using Android native camera
The idea is to check which files are in the gallery just before taking the picture and just after it, delete that one that is new.
It's not the cleanest solution but it works.
May It will helps you!
My app is saving some images on the SD Card, in the AppImages directory
The inbuilt gallery app is detecting these images and showing them on the gallery.
It is possible to hide these images and to be visible only for my app?
Thanks
Rename the directory from AppImages to .AppImages. The dot "hides" this folder from the system.
On an unrelated note, consider naming the folder something less generic to lessen the chance that it already exists.
You could stop the gallery from picking up your apps photos by putting a .nomedia file in the folder where they are stored. This will stop the gallery app from detecting your images, but a user still can open them in the gallery by using a file manager to navigate to the directory and selecting an image.
Hiding the images from both the user and the gallery is not possible, AFAIK.
No Need to hide the Picture.. just Rename the Extension like ".txt" it will show the pic like unsupported file
When I take pictures using android.hardware.camera and I save them to the following location /sdcard/dcim/camera/ they don't appear when I launch the gallery. Is there a process for getting them to show up in the gallery that I missed?
I can see my images using a file explorer and know they have been saved.
You need to run MediaScanner on the type of media that you have saved to make your changes(SDcard writes) transparent throughout the system.
MediaScanner is bundled with devTools package so you can either run it manually or you can also do it via Java code(right after the write to SDcard op). Google "MediaScanner" you will find plenty of examples.
Hope that helps.
