NFC - my third extension [FREE]

[Matanel325 (Matanel Shmailov)]

Write a short description

this extension has only 2 blocks - for check if NFC exists, and if turned on.
Note: I developed this extension because in the build-in component, does not have these functions!

Add a picture of all the blocks

Returns: ~boolean (true or false)

Returns: ~string (Return string (true or false). If not exists return: Your phone does not have NFC sensor).

You might want to resize the icon.

[Matanel325 (Matanel Shmailov)]

@bodymindpower

[bodymindpower (Anke)]

Do you see the attached image?

I don’t see it → Firefox

→ Chrome I see it.

@Kodular is there a way you can force this to be 16x16 no matter what size image is uploaded? Often people will make larger images for better resolution… If the img element has a specified size, it shouldn’t affect the image resolution.

[Matanel325 (Matanel Shmailov)]

yes, in kodular it is always working
just in app inventor it look like real size…

In this extension there was a big bug that caused other imported components to crash!

The repair is now done and the file is up to date. Anyone who downloaded - please delete the file immediately, and save the new file. If not - the system will crash.

thank you for your contribution!

Please remember to follow the naming conventions

Naming conventions for extension developers

If you are developing an extension, then please follow the naming conventions, which is UpperCamelCase for property, method and event names (i.e. the first letter should be a capital letter) and lowerCamelCase for parameter names, no underscores . Example [naming] All components and extensions follow the naming conventions… and these naming conventions have been setup by the MIT App Inventor team, see also the App Inventor Extensions document see here why naming conventions make sense …

Thank you

[Matanel325 (Matanel Shmailov)]

Ok I did it.
Also I changed the IsEnabled to only Enabled.

Hello and first of all thank you for this application.

I think there is a little problem with “enable”.

If I activate my NFC and click on “do it”, I get the message “true”. If I disable “False”, so far no problem.

On the other hand if I put a condition of the style when nfc is activated:

“call NFC.enable = true” then do it returns “false” to me when NFC is activated (so true). The result is identical if I activate or not the nfc or if the condition is true or false. the result is always the same “false”.

Also noted that if I want to put “nfc.enable” directly in an IF condition, it is impossible to attach (it is possible with then or else) while it works with “exists”.

@eps_prieur

Also noted that if I want to put “nfc.enable” directly in an IF condition, it is impossible to attach

Because it is a String, not a boolean. Check the first post for more info.

[eps_prieur (eps prof)]

Ok, but why do I get this result when dmon nfc is on? or off?

[WatermelonIce (Bryan)]

You’ll have to wait the developer’s reply.

Btw, you should use the red String “true” instead of the green one.
