AR View 3D won't work on Android devices

Bugs and Other Issues
1

The AR View 3D “Starttracking” block reports an error:

invoke: no method named `StartTracking' in class java.lang.Boolean
when used. It only works on iOS. Does anyone have a solution, such as a third-party software or a way to fix this bug in app inventor?

Where did you find such a block?

I can't find it in any component in Ai2.

You can see in the screenshot. The StartTracking method can be found in the ARView3D catergory.

This component was shown during the 2019 summit at MIT, it only works on iOS, as far as I remember. The server it was on wasn't able to build anything. What server are you using or is the extension released. It is not on App Inventor Extensions | Pura Vida Apps

The AR component is used in this project: Augmented Reality: Chicken Bowling

That is just a test server https://ar.appinventor.mit.edu/. Like I said, you can not build from that server.

It needs also a special companion

On the tutorial page it says:
Note: Support for Alexa projects is discontinued following the conclusion of our Amazon Future Engineers collaboration. Some features may not work properly. Please proceed at your own discretion.

Is there a way to get this template onto the normal MIT app inventor server? (https://ai2a.appinventor.mit.edu/)
When I tried exporting this project and then importing it to the normal server, it reported a bug and wouldn’t open the project.

Same. That happened to me too. I exported the .aia file, but when I import it, it says that the normal MIT App inventor server doesn’t have the Augumented Reality tab. It is like that the Augumented Reality tab is an extension or something that the Chicken Bowling template had already.

Given the life support level Ai2 MIT budget, this looks unlikely.

Maybe you can fund an extension writer?

If you are testing the AR capability on Android, you will need to sideload the companion app published on that server. This functionality is not yet part of the core Android app published through the Play Store.
