问题 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 . So, each time that the user wants to make a photo, he should click on the "take photo button" that starts an intent, and after having waited some seconds to start the camera, the user is able to take a picture; after that the photo is taken and accepted by the user, the camera closes and the picture taken is given

问题 I have searched around and found a few different solutions to this problem but none of them are really what I am looking for. I am developing an app that lets the user take an image by opening the camera via a MediaStore.ACTION_IMAGE_CAPTURE Intent as so...
