When I launch my android app in InstantApp mode, it fails to open camera even after granting relevant Camera permission.

I am creating Android Instant App where a user can capture an image and upload on the server.

I am using Camera2 API. InstantApp doesn't allow MediaStore.ACTION_IMAGE_CAPTURE intent as Android doesn't permit external storage permission.

The app is able to open Camera after asking relevant permission if I launch in normal (non-instant) mode.

But When I launch in InstantApp mode, it fails to open the camera. I see these logs in logcat.

09-26 07:33:29.182 7846-7891/com.project.snapdrive W/Camera: An error occurred while connecting to camera 0: -74 (Not a data message)

If you want to have a look at code, My Project is here.

I am using emulator Nexus 5X, Android 6.0, API 23.

  • Try launching the same app in your phone. – Daksh Gargas Sep 26 '17 at 03:16
  • I don't have Pixel or Nexus. I have other variants but those are not whitelisted by Google. – Vikash Sep 26 '17 at 03:18
  • I ran your instant app and got `java.lang.SecurityException: Lacking privileges to access camera service` error. There is an open bug about CAMERA permission denial in instant apps https://issuetracker.google.com/issues/66942980 – Julia K Sep 27 '17 at 00:42
  • Instant app works with the standard camera intent https://developer.android.com/training/camera/photobasics.html. I created a sample app with `MediaStore.ACTION_IMAGE_CAPTURE` and confirmed that photos could be taken from instant apps with the camera app. – Julia K Sep 29 '17 at 18:45
  • @JuliaK It didn't work for me. Could you please post your solution [here](https://stackoverflow.com/questions/44829710/instant-apps-camera-intent), if you are able to make it work? Thanks. – Vikash Oct 03 '17 at 16:25

    @Vikash You know what, it only works on O for me atm. All I did was copy the code from “Take a photo with a camera app” and “Get the thumbnail” at https://developer.android.com/training/camera/photobasics.html The camera opened and I was able to get a result from it, no camera permission needed. https://issuetracker.google.com/issues/66942980#comment3 – Julia K Oct 06 '17 at 23:50

That looks like a bug reproducible on the Android O. It could be reproduced as well with the sample Camera2Basic project adapted into an Instant App: Sample code

Can you check status of bug on the Google tracker for update of this bug.
