Android Question NFC in background and send the code to another app

[August Jimenez]

Hi,

I need to develop an APP to read a NFC card in backgroung and to paste the code to the active application. The behavior should be like the barcode reader. For example, I have a form in Chrome and the cursor in a text field. I need to read a NFC card and see the NFC ID in this field.

The code to read a NFC card is clear for me, but my problem is how to paste into the form field (like explained in the example before).

Thanks

Hi,

I'm assuming that the text field is in chrome so a good starting point https://www.b4x.com/android/forum/t...webpage-with-webview-and-webviewextras.34418/ have a look at post 10.

Thanks Jamie,

It is not exactly what I need. Imagine you have anything app opened, for example the "notes". What I need is to read a NFC card and see the ID in the note. The real need is to use a form in Chrome, but the behavior would be the same; paste the ID in the app opened.

Regards

The feature to read the NFC Code must be in the Notesapp then. You do not have any control over other apps.

The real need is to use a form in Chrome

Learn javascript, add a javascriptinterface to the page viewed and inject javascript-code to change any Dom-Element.

You can copy the code to the clipboard and show a toast message that tells the user to paste it.
