HOW TO: Use the Navigate control

Error Code 4003 & 404 in Navigation function

I've identified the problem and submitted a fix for review on our end. In the meantime, you can sideload an updated version of the companion for Android or join Apple TestFlight for the latest beta version.

Oh good news.
If it is companion bug, do you think if the app build, then no problem happened??

Thanks for you response.

If you use the modified companion app and it works, why not try a compiled app and see if it works ?

[Kang_HeeYoung]

Great!! It works

hi
This bug causes navigation to not work when building the .apk. And the companion is an older version than the current companion. A companion upgrade is needed quickly. How can I solve problems with companion upgrade and build?

How can I solve problems with companion upgrade and build?

Sorry, you cannot presently build your app using the Companion 2.70d1u , The Companion 2.70d1u ONLY works in development mode at the present time.

Everyone has to wait until MIT fixes the bug, until then you will not be able to build using Navigate. When will it be fixed? days, weeks, or more.

This 404 error issue was fixed July 7th

Changes between nb196 and nb197 (July 7, 2024)

This is a component release which includes bugfixes and improvements. It includes a new Android MIT AI2 Companion versions 2.71 (from Google Play) and 2.71u (directly downloaded from MIT App Inventor).

Features:

• New user interface. Go to Settings > User Interface Settings > Neo to try it out
• ChatBot component adds a new block, ConverseWithImage to ask questions about images (API key needs payment for gpt-4)
• Palette categories can be independently expanded/collapsed
• The main body of MIT App Inventor now loads via the CloudFlare content delivery network. This should result in faster startup of MIT App Inventor.
  • Note: Sites with restrictive firewalls will need to unblock access to https://.appinv.net (where the “” means any site name). This domain (appinv.net) is used exclusively to distribute the code of MIT App Inventor. Different host names are used for different versions.
• You can now set the “Origin” of Image Sprites. The origin is used to calculate when a Sprite is involved in a collision as well as the point it rotates around.
