我的任务是将Phonegap + Sencha projecto从Phonegap 1.2.0升级到2.1.0以及Sencha 2，我一直在Chrome + jetty下调试工作，这里修改之间的迭代更快。
在与迁移部分进行了一些讨论后，我得到了一个项目在Chrome上启动的点（即：我可以在调试器上执行我的启动方法，并且应用程序加载），但是当我在Android上尝试同样的事情时，我得到了未捕获的ReferenceError：app未定义。
在android中调用的HTML文件如下所示：

首先，我知道应用程序对于全局对象来说是一个糟糕的选择，我认为特定的东西在1.4.0和1.5.0之间发生了变化，因此，虽然对launch（）方法的原始调用如下：
app.launch（）;
我发现这在2.1.0中不起作用，我可以称之为：
app.app.launch（）;
这在Chrome中可以正常工作，从上面粘贴的代码调用fireCreateLocalStore（）结束调用它。
现在，当我在Eclipse中编译它并使用debug选项进行部署时，我看到logcat通过创建数据库对象（就在之前），当它到达launch（）行时，我从标题中得到错误：Uncaught ReferenceError：未定义app
我尝试将违规的全局更改为不那么冲突的东西，比如html和App.js中的MyApp（加上默认视图）无济于事，因此现在，我有点坚持这个。
顺便说一句，我的App.js看起来像这样：
// Main application entry point
Ext.application({
name: 'app',
phoneStartupScreen: '../resources/images/LOADING_01.png',
tabletStartupScreen: '../resources/images/LOADING_01.png',
glossOnIcon: true,
fullscreen: true,
autoCreateViewport : true,
// the controller will take care of creating the view
//controllers: ['Configuration', 'ImmediateAlert', 'Guardian', 'Log'],
controllers: ['Configuration', 'ImmediateAlert', 'Guardian'],
// You could delete this, here only to illustrate
// the sequence of events
initialize: function () {
console.log('app initialize');
this.callParent();
},
launch: function() {
console.log(app);
this.launched = true;
Ext.create("app.view.Viewport");
this.mainLaunch();
},
mainLaunch: function() {
//if (!device || !this.launched) {return;}
if (!this.launched) {return;}
console.log('MainLaunch : loading in ' + currentPlatform );
Ext.getCmp('navigationView').getNavigationBar().add({id: 'save',
text: 'Guardar',
ui: 'light',
align: 'right',
})
if (app.store == undefined)
app.store = new Object();
app.store.contacts = Ext.create('Ext.data.Store', {
model: "app.model.Contact"
});
app.store.alerts = Ext.create('Ext.data.Store', {
model: 'app.model.Alert',
});
app.service.ProsegurLocalStorageStore.populateStores(app.store.alerts);
app.service.ProsegurLocalStorageStore.populateContactStores(app.store.contacts);
var config = app.service.ProsegurLocalStorageStore.getConfiguration();
console.log('ATENCION' + app.configuration.GeneralConfiguration.fireAlertService());
if (config.data.wsBaseURL != null && config.data.wsBaseURL != '') {
app.configuration.GeneralConfiguration.prosegurServiceBaseURL = config.data.wsBaseURL;
}
if (config.data.wsBaseCriticalURL != null && config.data.wsBaseCriticalURL != '') {
app.configuration.GeneralConfiguration.prosegurServiceCriticalBaseURL = config.data.wsBaseCriticalURL;
}
if (currentPlatform == "MacOS"){
navigator.geolocation.getCurrentPosition();
}
Ext.MessageBox.YESNO=[{itemId:'no',text:'NO'},{itemId:'yes',text:'Si'}];
Ext.MessageBox.OK = {itemId:'ok',text:'Aceptar'};
Ext.MessageBox.OKCANCEL=[{itemId:'cancel',text:'Cancelar'},{itemId:'ok',text:'Aceptar'}];
Ext.Date.dayNames = [
'Domingo',
'Lunes',

];
Ext.Date.monthNames = [
'Enero',
'Febrero',
'Marzo',

Ext.Date.monthNumbers = {
'Ene': 0,

};
if (Ext.is.Android) {
Ext.EventManager.onWindowResize(function() {
Ext.Viewport.scrollToTop();
Ext.Viewport.updateBodySize();
Ext.Viewport.fireEvent('resize', Ext.Viewport, Ext.getBody().getSize());
app.views.viewport.getActiveItem().fireEvent('resize');
});
};
app.service.ProsegurServiceCallbackDaemon.run();
}
});
“app”很可能与“navigator.app”冲突，后者是一个PhoneGap API。如果您可以更改Sencha应用程序的名称，那么这可能是您最好的选择。
