Android: How To Capture Multiple Photos With The Same Camera Intent

I made an Android app that takes photos one by one, stores them, gives a preview to the user, etc...all of these tasks are accomplished with an intent of type ACTION_IMAGE_CAPTURE.

Solution 1:

making an intent to "INTENT_ACTION_STILL_IMAGE_CAMERA"

This is not really analogous to any of your other options. For example, you have no idea if any pictures were taken, where they were stored, etc.

as a consequence, I think that is not possible to control the interface or the behavior of the called app

Correct. This is the same as with ACTION_IMAGE_CAPTURE.

using the package "Camera2"

This is the same as "make a picture taking code by yourself", except that you identified a particular Android API for it.

It is possible for a beginner-intermediate developer to accomplish this task following one of the way mentionned above (or a different one)?

Use a third-party camera library (Fotoapparat, CameraKit-Android, etc.).
