Like I said earlier everything was working fine but suddenly stopped. I restarted my phone many times, I change phone and nothing. I did Invalidate Caches/Restart but still have the problem.


Solved! It was because of my home wifi network. I turned on hotspot on another phone and connect my laptop and phone to test and worked. I still don't understand how earlier everything was working on my home wifi and suddenly stopped.
Someone know how is it possible?

AzureSpatialAnchors basic demo not saving

I just checked out the spatial anchors demo from GitHub, changed the keys and deployed it to my Samsung S8 successfully.

Its Working fine in android lower versions.

As the Problem shows: You need to add internet access permission in the app.

And at last when app asks for internet access in popup allow the app to use internet!

There can be two problems. First the firewall can prevent access. Switch it off for a test. Second: Maybe Tomcat is bound to localhost/127.0.0.1 only. Have a check in its settings.

Fixed,My public IP of my PC is different,Public IP of android phone is different(connected to another wi-fi),But both should be same

also I've added in my AndroidManifest.xml following lines:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
but still getting the same exception

Simple solution: set your target SDK back to 22
Clean Solution: Request the Runtime Permissions
