How do I avoid saving captured image in my device?

I have to create functionality for an application where I have to take pictures and save it to a SQLite database. I have implemented the camera for now using the camera intent in android, but the image gets saved to the gallery. I have read the Camer2 and CamerX API documentation and the image still gets saved to a device folder. Is there any way to avoid this?

You can checkout https://stackoverflow.com/a/64651558/277368 on how to get in-memory image with CameraX. Then you need to serialize the image and save it to SQLite on your own.

Uploading image to a database

I'm trying to develop an android app which displays the images stored in a database hosted on a server . As of now , i'm using Firebase , which supports only text and i'm storing the url of the image to be displayed in my app .
Are there any other options for me to store images on the internet and retrieve them in my App ?

You can encode the images themselves using Base64 and storing them directly. But what you are doing is usually the best option.

Google+ share image using URL like Facebook

I'm currently looking for a way to share in Google+ using URL from web and not from local storage. Problem is that I've used UniversalImageLoader to cache my image and I don't have the image file of the images I wanted to post on my share. I wanted it to be as simple the way facebook done their sharing but using the setContentUrl(Uri.parse(IMG_URL)) will give me the way I wanted it minus the image URL below the post.
Other workarounds I'm thinking is to download the image using the URL, store it somewhere on the device then share it using the setStream(Uri.parse(IMG_URI)) but only problem is that I will need to wait more compared to sharing using URL.
Now is there's any way I can achieve a faster image sharing on Google+? Or if ever is there's a way I can convert the cached file back into image so that I can share it using Stream?

how to view all images in android's built- in gallery from a php page

I am developing an application to display all the images in android's built-in gallery in to a php page. I posted the uri (content://media/extrenal/images/media) of the gallery images to the php page. I was not able to recreate images by using webView's function loadUrl().
Should I need to upload the whole gallery to another directory and display the images?
Or passing the bitmap itself will do?
Please suggest me an idea to solve the problem.

I think you should make an ashynchronous connection of your application with an php application on the server, which will tell the android app to upload the requested image, and when the java app receives the upload command, make the app upload the picture to the server, and make the server php app display the image uploaded. I know this is a bit complicated, but this is the only thing that is comparatively easier than doing socket transports and other things. Good luck :)
