Not able to parse bug report in Battery Historian

Submitted by Arpita Singh on Tue, 10/01/2019 - 01:28

Hi,

I'm able to generate a bug report from TC75 and analyze it using Battery Historian.
But when I try to do the same with TC57 and TC77 it throws me an error saying : "Exception found in battery dump."

It says that it is unable to find the zone info file in the generated bug report.
I'm following the same process with all 3 devices.

I've attached an image with the error for reference.

Thanks in advance,
Arpita

Hello. I'm testing the connection to a ZTC ZT230-203dpi ZPL printer. I tried using the demo program ZSDK_DemosAndroid provided in the link-os sdk package. However, a ZebraPrinterLanguageUnknownException is thrown when this line of code is being run:
printer = ZebraPrinterFactory.getInstance(printerConnection);

Here's the URL of the printer:

Any ideas? Thanks in advance!

Restrictions on non-SDK interfaces with Android Pie

Submitted by Darryn Campbell on Thu, 09/26/2019 - 02:51

Starting with Android Pie (API level 28), Android will start restricting which APIs your application can call if they are not part of the public API.  These restrictions apply whenever an app references a non-SDK interface or attempts to obtain its handle using reflection or JNI but do not affect calls to the EMDK or other third-party APIs.

Variable Data Scans In Enterprise Browser

Submitted by Jack Christensen on Tue, 07/16/2019 - 11:29

I am trying to develop a web app that allows users to scan variable text into text inputs, print a label with the variable data on it, then reset the fields. I would like to embed all the label data into the html file so that the labels don't have to be exported to every printer on the network.

I can print static ZPL from the web app but I can't seem to get my printData function to recognize a variable with HTML data. Is there a way to do this?
