Autoenter after Suspend / Hibernation disabled

Hello, we are developing for Android-Device TC8000 with Enterprise Browser.

 

We have encoutered a problem if the Device wakes up from Suspend / Hibernation with the Enterprisebrowser still open.

 

The Scanner takes a short while to become active again ~10 - 20 Seconds the AutoEnter is not working.

 

First we tried to solve it with the EB.Barcode API but havent found a OnWakeup event or something like that.

 

Then we used the rhoapi-modules.js and elements.js API  with Metatags:

 

<META HTTP-Equiv="scanner" Content="Enabled:SCN2">

<META HTTP-Equiv="scanner" Content="AutoEnter:Enabled">

<!--   <META HTTP-Equiv="scanner" Content="Start"> -->

<META HTTP-Equiv="scanner" Content="picklistMode:hardwareReticle">

 

We changed the EB.Barcode to the "scanner" equivalent.

 

scanner.enabled = 'SCN1';

scanner.autoEnter = 'enabled';

 

Now the AutoEnter works, but the Scanner ist still deactivated for ~10-20 Seconds until you can Scan again.

 

Is there a way to increase the Performance to Wakeup the Scanner?

Do we have to use the rhoapi-modules to solve the Autoenter Problem? I am asking this since ZEBRA suggests to use the EB. APIs.

 

Thanks in advance!
