Do you see the attached image?

I don’t see it → Firefox

→ Chrome I see it.

[hammerhai (Nathan)]

@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…

[Matanel325 (Matanel Shmailov)]

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

Ok i will do it now
~
I did.

[Taifun]

@Matanel325

I did.

thank you… you also might want to replace IsExists by only Exists
Taifun

[Matanel325 (Matanel Shmailov)]

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

[eps_prieur (eps prof)]

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.

[eps_prieur (eps prof)]

Thank you indeed it is necessary to put true in text!

[Matanel325 (Matanel Shmailov)]

I don’t know to help you, sorry

[Taifun]

@eps_prieur

it is necessary to put true in text!

this is not how the extension should work…
the developer of the extension @Matanel325 might want to fix this and return a boolean value rather than a string

@Matanel325

Returns: ~boolean (true or false)

[Matanel325 (Matanel Shmailov)]

I will not do it because the code will not compile if i will do it.
In block “is enabled”, the code does if statement for if exists and also if statement for if enabled.
Sorry for this, but if i will remove the if statement of is exists, the if enabled will return error.

[Taifun]

@Matanel325

I will not do it because the code will not compile if i will do it.

which error message do you get?
what about

  @SimpleProperty()
  public boolean Exists() {
    ....
    return yourBooleanValue;
  }

Taifun

[Matanel325 (Matanel Shmailov)]

I will send you the code in pm

Dear @Matanel325

I saw your extension and it seems very good. As you seem to be quite expert in working with nfc in kodular, do you think you would be able to make a new extension that can make the NFC read-only? Thanks!

Ps. @Taifun if you have any suggestions…
