I need to let the user take a picture (from the gallery or from a camera app) with Android 6.0.
Because I don't need to control the camera, I wanted to use an intent as describe here:
However, if you don't need such control, you can just use an ACTION_IMAGE_CAPTURE intent to request an image. When you start the intent, the user is prompted to choose a camera app (if there isn't already a default camera app), and that app takes the picture. The camera app returns the picture to your app's onActivityResult() method.
https://developer.android.com/preview/features/runtime-permissions.html
But for this ACTION_IMAGE_CAPTURE, you need to fill the extra "MediaStore.EXTRA_OUTPUT" which is an Uri to a temp file (without this param I will have only a thumbnail). This temp file must be into the external storage (to be accessible by the camera app). You need the permission WRITE_EXTERNAL_STORAGE to create a file on the external storage.
So it's not possible to capture an image through native dialogs/apps without the permission android.permission.CAMERA or android.permission.WRITE_EXTERNAL_STORAGE. Is that correct?
Thanks
It is possible if you on android 4.4+, you can specify MediaStore.EXTRA_OUTPUT, to be a file under your package-specific directories
Starting in Android 4.4, the owner, group and modes of files on external storage devices are now synthesized based on directory structure. This enables apps to manage their package-specific directories on external storage without requiring they hold the broad WRITE_EXTERNAL_STORAGE permission. For example, the app with package name com.example.foo can now freely access Android/data/com.example.foo/ on external storage devices with no permissions. These synthesized permissions are accomplished by wrapping raw storage devices in a FUSE daemon.
