Android vision - Face detector dependencies are no

问题:

I am trying to test the google mobile vision api, for face detection, so I started with the demos from GitHub mobile vision. I tried both apps, FaceTracker and photo-demo, and the same issue rises with downloading the native face detector library.

For Nexus 5x, Galaxy S6 Edge not working, Galaxy S4, Galaxy Alpha is working.

What I see in the logs, when not working is:

For the app:

After doing some digging in the logs, by applying the vision filter for tags I see:

Similar questions:

1. Google Vision barcode library not found
2. FaceDetectorHandle﹕ Native face detector not yet available. Reverting to no-op detection

Tried the solution with freeing up space, clearing cache, no result.

What can I do next ? Is it possible to manually download the libraries ? Does anyone have a clear indication why is the library not downloading ?

EDIT

So it looks like there is an issue with the Mobile Vision api https://github.com/googlesamples/android-vision/issues/98. Hope the developers come with a solution soon.

EDIT

The issue has been resolved by updating the play service library.

According to the release notes of Google Play Services v9.0 there was a bug in the service and it was disabled.

In release v9.2 it was enabled again. Check out the release notes: https://developers.google.com/vision/release-notes#bug_fixes

My problem was with text (TextRecognizer) not face and the problem was storage, I had 300MB free but it needed 10% of my phone according to this link

When is the intent ACTION_DEVICE_STORAGE_LOW broadcasted?
