1. Overview
ET-L10 is the device that is suitable for light work which is located between the conventional
rugged handy terminal and a smart phone. This document is a development guidebook written
for the ET-L10 application developers.
ET-L10 was developed as the device for customers who want to use smartphones for work but
are not satisfied with smartphones.
Conventional rugged handy terminal required specialized knowledge to control barcode scanner,
but ET-L10 does not need it.
From the getting date, it is set to be able to read all barcodes with standard Android
application.
Customers who want to make advanced settings for the barcode scanner can use the setting
tool instead of modifying their application.
Of course, they can control the barcode scanner also from the application by issuing scanner
intents.
Refer to the "Barcode scanner control manual" for details on the setting tool and the intent for
controlling the barcode scanner from the application.
