Try to desperately to capture exceptions and log them to the console.

exceptionwrapper.js

// http://stackoverflow.com/questions/5931033/how-can-i-know-if-a-javascript-exception-occurred-in-a-phonegap-application-and

(function(){

window.onexception = function(e) {
  console.log("Got an exception ", e, e.stack);
};





/**
 * Wrap function with exception caturer.
 * */
var captureExceptions = function(origFn) {
  return function () {
    try {
        origFn.apply(this, arguments);
    }
    catch  (e) {
      window.onexception(e);
      throw e;
    }
  };
};


/**
 * Wraps callbacks in object methods
 *
 * */
var wrapCallbackFunction = function(obj, fnName, callbackIndex) {
  var origFn = obj[fnName];

  obj[fnName] = function() {
    var args = [].slice.call(arguments);
    args[callbackIndex] = captureExceptions(args[callbackIndex]);
    origFn.apply(this, args);
  };

};



wrapCallbackFunction(window, "addEventListener", 1);
wrapCallbackFunction(Node.prototype, "addEventListener", 1);
wrapCallbackFunction(window, "setTimeout", 0);
wrapCallbackFunction(window, "setInterval", 0);



}());

How to capture rest of the exceptions?
