Android App that listens to HTTP requests and executes commands -- 2

Description: Android App that listens to HTTP requests and executes commands Goal: To print, open cash, display text on external digital display from another device on the network through curl HTTP POST requests. Notes: Print, open cash register, and display text on external digital display examples are provided in the SDK attached. SDK printing supports special characters and barcodes. Screenshots of the example app in that same SDK are attached to show functionality. Testing: -Teamviewer will be provided to test progress on the device. Hardware: -ELO PayPoint Android with integrated printer, cash register, and digital display. Requirements -App should listen/catch HTTP POST requests (HTTP POST requests are sent with PHP curl command from another device on the network) -Possible variables can be passed on the HTTP request: print, opencash, displayonscreen. -App should either print the text, open cash register, or display text depending on which variable was passed -Print variable should support printing of barcodes, special characters and end of lines (all supported in SDK). -The GUI should only be a real time log of the HTTP requests received with scroll bars, 100 lines of log is enough. Example: $time - $OriginIP - $variablepassed(Print/openregister/displaytext) - $valueofvariable End of line. -App should run in the background. Example 1: -HTTP request sent to android IP with variable name="print" value="print this text" -Android prints "print this text" Example 2: HTTP request sent to android IP with variable name="opencash" value="1" -Android opens cash register Example 3: HTTP request sent to android IP with variable name="displayonscreen" value="Total: 19.99" -Android displays on the external digital display "Total: 19.99" Example HTTP POST app should respond to (request is sent with php from another device on network): <?php $params=['print'=>'Print this') $defaults = array( CURLOPT_URL => 'IPOFANDROID', CURLOPT_POST => true, CURLOPT_POSTFIELDS => $params, ); $ch = curl_init(); curl_setopt_array($ch, ($options + $defaults)); ?>
