Purpose

A minimal Android Mobile project connecting to iDempiere besides the highly complex SFAndroid/SpinSuite that its creators have no intention to work with the also equally complex iDempiere ERP project.
A completely originally done project managed by me so that I can answer, maintain and improve it without reference to an alien project that no one can properly address.
Thus the project source-code easily understood and modifiable with no debugging hassle.
With well described instructions in technical forum to guide developers and users.

Using Android Studio SDK version 25 usable backward minimal 15.
Only two simple short main classes to read and maintain
Integration to download ZXing Barcode scanner that is set to read up to QR code.
Reference how I solve simple developer issues:
- Connecting to Postgres database directly
- Handling basic activity and views
- AsyncTask handling of UI thread

SQL writing made to be open and dynamic for any table-field to be updated directly.
QR-code printout format: UPDATE [Table] SET [Set]=[Set2] WHERE [Where]=[Where2]
Optimal response popup of success/fails
Handle multiple scans before Update DB
Immediate Kanban board reflection for high user experience.

Performance for using direct jdbc connection instead of Web Services
- It is not an issue for low controlled offloading updates. iDempiere server also need not be up for 24X7 shopfloor operations.
Security
- Can be controlled by many other means as this is Open Source for implementor to harden it. Code is only two main classes, very short for fast understanding.
Logging
- Is automatic by use of pg_log at Postgresql level.
