Android HTTP API

While DXU Service is enabled and running, DXU Android provides an HTTP endpoint that can be used by local applications to control the scanner. This is useful for web-based applications that need to be able to control the scanner.

Conventions​

In the documentation below, the following conventions are used:

  • dxuPort is used to indicate the port on which DXU is running. The default value is 8080.

  • Only localhost connections are allowed, i.e. connections to http://127.0.0.1:dxuPort/scan.

  • All APIs, unless otherwise noted, are HTTP GET methods.

  • API responses return no content unless otherwise indicated.
