Question

I am using Sencha Touch 2.3.1 with Sencha CMD 4.0.2.67 in conjunction with Cordova 3.4.

The purpose of my doing is to know how to use Sencha tools to create the mobile app and then using Sencha CMD + Cordova to build and run on Android and Windows Phone 8 platforms.(I have set up both environment on my PC and managed to build and run my mobile app just with Cordova for Android and WP8).

Now, I followed the tutorial on Sencha about creating the 1st app(http://docs.sencha.com/touch/2.3.0/#!/guide/first_app), encountered many odd crashes but fortunately, I somehow fixed all of them(I'm surprised by myself). The learning procedure is very exciting for me so far and I found that Sencha CMD and even starts WP and Android emulators!

Now the problem is, when I execute the command sencha app build -run native, both platforms have my app generated and run, but the panels I created under Sencha, do not show up. What I get is the launching screen with 4 flashing dots.

It supposes to show a UI which has 3 tabPanels.

Here is my app.js:

launch: function () {
        // Destroy the #appLoadingIndicator element
        Ext.fly('appLoadingIndicator').destroy();

        Ext.create("Ext.tab.Panel", {
            fullscreen: true,
            tabBarPosition: "bottom",

            items: [
                {
                    title: 'Home',
                    iconCls: 'home',
                    cls: 'home',

                    html: [
                         '<img src="http://staging.sencha.com/img/sencha.png" />',
                        '<h1>Welcome to Sencha Touch</h1>',
                        "<p>You're creating the Getting Started app. This demonstrates how ",
                        "to use tabs, lists, and forms to create a simple app.</p>",
                        '<h2>Sencha Touch</h2>'
                    ].join("")

                },
                { // the 2nd item}, {// the 3rd one}

And here is what the Sencha generated under MyApp/cordova/platforms/wp8 in index.html

As you can see here "Ext.Blink(id......., .... ,...., js:[xxxx,'app.js'])".

So here is the app.js under wp8/www folder

(function(){var global=this,...many code more than 570000 letters, so I have to cut the m down..................if(window.scrollY!==0){window.scrollTo(0,0)}}})}}});Ext.define("Ext.viewport.WindowsPhone",{requires:[],alternateClassName:"Ext.viewport.WP",extend:Ext.viewport.Default,config:{translatable:{translationMethod:"csstransform"}},initialize:function(){var a=function(d){var c=d.srcElement.nodeName.toUpperCase(),b=["INPUT","TEXTAREA"];if(b.indexOf(c)==-1){return false}};document.body.addEventListener("onselectstart",a);this.callParent(arguments)},supportsOrientation:function(){return false},onResize:function(){this.waitUntil(function(){var c=this.windowWidth,f=this.windowHeight,e=this.getWindowWidth(),a=this.getWindowHeight(),d=this.getOrientation(),b=this.determineOrientation();return((c!==e&&f!==a)&&d!==b)},function(){var b=this.getOrientation(),a=this.determineOrientation();this.fireOrientationChangeEvent(a,b)},Ext.emptyFn,250)}});Ext.define("Ext.viewport.Viewport",{constructor:function(b){var c=Ext.os.name,d,a;switch(c){case"Android":d=(Ext.browser.name=="ChromeMobile")?"Default":"Android";break;case"iOS":d="Ios";break;case"Windows":d=(Ext.browser.name=="IE")?"WindowsPhone":"Default";break;case"WindowsPhone":d="WindowsPhone";break;default:d="Default";break}a=Ext.create("Ext.viewport."+d,b);return a}});Ext.define("MySenCha.view.Main",{extend:Ext.tab.Panel,xtype:"main",config:{tabBarPosition:"bottom",items:[{title:"My Home",iconCls:"home",styleHtmlContent:true,scrollable:true,items:{docked:"top",xtype:"titlebar",title:"Welcome to Sencha Touch 2"},html:["You've just generated a new Sencha Touch 2 project.

Reload now?",function(a){if(a==="yes"){window.location.reload()}})}});

I finally found where my code, as you might see that my code has been included in the app.js under wp8/www folder.

But when I tried to run from the index.html or deploy the app onto my device, I only got Cordova splash screen and a blue screen, no my tab panels at all.

I also checked the log generated during building and running my app and found that when running WP8 app, it said:

[TypeError: undefined is not a function]

Then I when to the generated index.html and did find many of them.

Incidentally, I ran my app on 3 browsers: IE10, Chrome (latest), Firefox (just downloaded). Only Firefox can run the Sencha Touch app successfully. The rest of others just can show the blue screen in the demo without characters and pic, no tab panels docked at the bottom either.

I feel like I am very close to the final success of my learning.

Here is the log for running: cordova run --device.

Update 3

Here are commands I ran to generate app and deploy on my device:

  1. sencha -sdk /path/to/touch-sdk generate app TestSenchaApp TestSenchaApp
  2. cd TestSenchaApp
  3. sencha cordova init com.test.myApp
  4. edit 'cordova.local.properties' 4a. change the line cordova.platforms=ios to cordova.platforms=wp8 4b. save the file and exit your editor
  5. sencha ant cordova-sencha-prepare
  6. cd cordova
  7. cordova serve wp8 -> I tested on IE, Chrome and Firefox, it runs on all of them without an error.
  8. cordova run --device

Ran step 8, still got the same issue.

Was it helpful?

Solution 2

Finally, I spotted the culprit of this problem.

It was because I have a messy cordova at .cordova/lib. So what I did was deleted the entire .cordova under C:\Users\\

And reinstalled cordova.

Then the problem solved :)

Hope it helps, cheers

OTHER TIPS

@Franva, now I can see the problem. Is really the "require". I will explain:

Sencha Touch is a framework with a lot of components. When you use the "x-type" you are using a inheritence of a specific component.

Example:

"Ext.create("Ext.tab.Panel"": you are using Panel, and the components are modular in sencha, you can see the source here

When you are developing, the micro-loader of sencha touch will load this file "on the fly" for you. But when you use cmd, the generated package will only contain the parts of sencha touch that you define. That is to not make a package with big size with components that you wont use.

So, for your package works you have to define the requires in your components/app. If going to use MVC (model-view-controller) or another multiple files system to create your app so you can put the requires specifics for each file, the cmd will add the component once.

The list of components that you are using:

  • Ext.tab.Panel
  • Ext.dataview.NestedList
  • Ext.Panel
  • Ext.form.Panel
  • Ext.field.Text
  • Ext.field.TextArea
  • Ext.field.Email
  • Ext.Button

If you open your console on development (ff or chrome) sencha touch will show you a warning about this missing requires.

I didnt search about another errors, but with this change require everything probably will show:

requires: [
    'Ext.MessageBox',
    'Ext.tab.Panel',
    'Ext.Panel',
    'Ext.dataview.NestedList',
    'Ext.form.Panel',
    'Ext.field.Text',
    'Ext.field.TextArea',
    'Ext.field.Email',
    'Ext.Button',
],

You should read the docs about compoenents, will help you.
