The yellow buttons are defined as triggers so they can't be detected as keys in standard Javascript. However, if you use Zebra Enterprise Browser then you can detect triggers using the EB.KeyCapture.captureTrigger() method as detailed here : https://techdocs.zebra.com/enterprise-browser/5-0/tutorial/keycapture/

Because the yellow keys will only work with a Zebra device, you could capture the onKeyUp/Down in the Android plugin, such as here in this sample project https://github.com/NDZL/ionic-cap-echo/blob/main/android/src/main/java/com/ndzl/cap/echo/EchoPluginPlugin.java 

When the key code is captured, pass it back to the common UI code as I did here  with notifyListeners  https://github.com/NDZL/ionic-cap-echo/blob/b00a7f102a9dd1874edc020a0097bacee6c7d808/android/src/main/java/com/ndzl/cap/echo/EchoPluginPlugin.java#L73 

Finally, in the js/ts code, receive the value in a locally defined listener such as this one

https://github.com/NDZL/ionic-cap-use-datawedge-echoplugin/blob/c421ff32dbb3acd6229137c474e27abeb9320ece/src/app/tab1/tab1.page.ts#L24

Please recall that the yellow buttons are mapped to trigger the barcode scanner, so if you just need to scan, refer to DATAWEDGE https://techdocs.zebra.com/datawedge/13-0/guide/about/, which relies on Intents to deliver data and be configured.

Hello,

i checked in android Logcat view during press HW button (Left, Right and Scan buttons)

i found that 136, 137 and 138 code getting when press button.

can you please suggest how to "HardKeyDownEvent" event handle in cordova application  using javascript or plugin?

Thank you

Hi Patel, in my previous answer above, I showed you a way to achieve what you requested. 

Did you try it? Can you share the challenges/results you faced?

Thanks
 

Hello Nicola

yes, i checked but not return keycode value in app side

i need to only keycode value when button press, because i using cordova plugin for scanner, not using DATAWEDGE
like,. after return key code value, i will decide this key to start RFID or 2D scanner (both are working with cordova plugin)

can i directly, find keycode value in app after press Hardware button?

Thank you
Chetan Patel
