mobilefirst app ionic crashes upon tapping android button (which override app.overridebackbutton() ).
i wrote simple test app (new project, new workspace), first without ionic adding ionic references: without ionic works fine, no inherent errors in console, with ionic 2 errors:
as app starts:
"error in success callbackid: app1084986710 : error: unknown event action undefined", source: file:///android_asset/www/default/worklight/cordova.js (309)
when tap button (from page 2)
w/unimplementedwebviewapi(21373): unimplemented webview method onkeydown called from: android.webkit.webview.onkeydown(webview.java:2389)
updates:
if remove wl.app.overridebackbutton(goback); , wl.app.resetbackbutton(); js functions both errors persist, , app still crashes upon tapping button.
if link/include ionic css , js remove ionic content (no ng-app property, no app.js reference index.html) button override works fine.
index.html
<!doctype html> <html style="height:100%" ng-app="mytryout" id="content"> <head> <meta charset="utf-8"> <title>tryout</title> <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=0"> <link rel="stylesheet" href="css/main.css"> <link rel="stylesheet" href="css/ionic.css"> <link rel="stylesheet" href="css/ionicons.css"> <script>window.$ = window.jquery = wljq;</script> </head> <body onload="initload()"> <div id="container"> <!-- content loaded here --> </div> <script src="js/main.js"></script> <script src="js/messages.js"></script> <script src="js/initoptions.js"></script> <script src="js/ionic-bundle.js"></script> <script src="js/app.js"></script> </body> </html> page1.html

<!doctype html> <html> <h2>page 2</h2> <button class="button button-block button-assertive" onclick="goback()">back</button> </html> main.js
function wlcommoninit(){ } function initload() { goback(); } function gotopage2() { $("#container").load("html/derp.html",function(){ console.log("i'm in page 2"); wl.app.overridebackbutton(goback); }); } function goback() { $("#container").load("html/dorp.html",function(){ console.log("i'm in page 1"); wl.app.resetbackbutton(); }); } app.js
var mymodule = angular.module('mytryout', ['ionic']);
sorry i've been busy. i'm writing outcome of requested tests here in struggle clarity.
i tried, in order:
1 - virgin mfp app (new mf project --> run as.. --> run on mf server --> build apk)
2 - added myoverride() function main.js , onload event body tag in index.html (see code below)
3 - virgin "hello mobile first" app references ionic source files, no ionic login (i.e. no ng-app attribute on body element)
4 - virgin "hello mobile first" app button override code (as above), references ionic source files, no ionic login (i.e. no ng-app attribute on body element).
5 - virgin "hello mobile first" app button override code (as above), references ionic source files, , ng-app attribute on body element.
in 5 cases upon starting app got these errors in logcat:

//// main.js //// function myoverride() { wl.app.overridebackbutton(function(){ alert("you pressed button!"); }); } this looks quite straightforward reproduce anyway, i'd appreciate if test on end , see if behaves same. clearer mayhem, guess...
