In phonegap, buffer the outputs to console.log to help hunting down errors that would otherwise be missed.

console_buffer.js

var console_buffer = {
  isBuffering: false,
  logBuffer: [],
  preservedConsoleLog: null,
  start: function() {
    "use strict";
    console.log('INFO: log buffer starting'); // will be lost
    console_buffer.preservedConsoleLog = console.log;
    console_buffer.isBuffering = true;
    console.log = function() {
      // needs to be from within scope
      console_buffer.preservedConsoleLog.apply(console, arguments);
      if (console_buffer.isBuffering) {
        console_buffer.logBuffer.push(arguments);
      }
    };
    console.log('INFO: log buffer started');
  },
  empty_buffer: function() {
    console_buffer.logBuffer = [];
  },
  end: function() {
    // TODO: Auto-end with a timeout in case never called.
    console_buffer.isBuffering = false;
    for (var i = 0; i < console_buffer.logBuffer.length; i++) {
      console.log('BUFFERED:' + console_buffer.logBuffer[i][0]);
    }
    console_buffer.empty_buffer();
    console.log('INFO: log buffer ended');
  }
};
