Angular2 custom request

I am using a custom HTTP request class for adding a Authorization Header to all of my requests, this works fine on almost every android device. Wired thing now is that I got some customer complaints that they are getting the 'No internet connection' error although they have a working network connection (other apps work and the errors are transmitted to the Sentry servers also).
As I am using Sentry error tracking I found out that these customers are all getting the error because the timeout error is thrown after 10 seconds for the first request at app start.
I guessed that something has to be wrong with this request so I built an alpha version for a limited number of users to track down the error (I send the options of every request to Sentry), but the requests look fine.
Next guess was that something is wrong with cordova-plugin-nativestorage on these devices but as I am catching them it should at lease return an empty token. No clue how to fix it right now. Any advice is appreciated!
export class CustomRequest {
apiToken: string = '';
constructor(private http: Http) { }
protected request(options: any): Observable<any> {
// If Native Storage doens't find a token, return an empty
let errorNativeStorage$ = function (): Observable<any> {
return Observable.of({ Token: '' });
};
// Get Token form Native Storage
let token$ = Observable.fromPromise(NativeStorage.getItem('JWT'))
.catch(errorNativeStorage$);
// Handle request errors
let genericError$ = function (error: Response | any): Observable<any> {
let errMsg: string;
if (error instanceof Response) {
const body = error.json() || '';
const err = body.error || JSON.stringify(body);
errMsg = `${error.status} - ${error.statusText || ''} ${err}`;
} else {
errMsg = error.message ? error.message : error.toString();
}
console.error(errMsg);
Raven.captureException(error, { extra: { errorMsg: errMsg } });
return Observable.of({
Errors: { General: 'No internet connection.' }
});
};
// the request
let request$ = (options) => {
return this.http.request(new Request(options))
.retryWhen(error => error.delay(1000))
.timeout(10000, new Error('timeout'))
.map((res: Response) => res.json())
.catch(genericError$);
};
// get the token and build request
return token$
.map(jwt => {
if (options.body) {
if (typeof options.body !== 'string') {
options.body = JSON.stringify(options.body);
}
options.body = options.body.replace(/ /g, '').replace(/\r?\n|\r/g, '');
}
options.headers = new Headers({
'Content-Type': 'application/x-www-form-urlencoded, application/json'
});
if (jwt.Token) {
options.headers.append('Authorization', `Bearer ${jwt.Token}`);
}
Raven.captureMessage('request options', { level: 'info', environment: 'live', extra: options });
return options;
})
.switchMap(options => request$(options));
}
}
I am using:
Ionic 2.0.0-beta.11
Angular 2.0.0-rc.4
Most recent version of NativeStorage plugin from github
Devices with the error (only two examples, there are more):
Samsung SM-N910F (Webview: Chrome Mobile 53.0.2785, Android 6.0.1)
Samsung SM-G800F (Webview: Chrome Mobile 53.0.2785, Android 5.1.1)

If somebody's interested: The root cause was that people that upgraded Android somehow lost the chrome webview app and Angular was not working without one (of course). I solved it by packaging the crosswalk-webview in my app!

Keypress event not working on Android device

I have a directive which controls my input value desired formatted or not.
directive('validNumber', function(shareDataService)
{
return
{
require: 'ngModel',
link: function(scope, element, attrs, ngModelCtrl)
{
if(!ngModelCtrl)
{
return;
}
ngModelCtrl.$parsers.push(function(val) {
if (angular.isUndefined(val)) {
var val = '';
}
var clean = val.replace(/[^-0-9\.]/g, '');
var decimalCheck = clean.split('.');
if(!angular.isUndefined(decimalCheck[1]))
{
decimalCheck[1] = decimalCheck[1].slice(0,2);
clean = decimalCheck[0] + '.' + decimalCheck[1];
}
if (val !== clean)
{
ngModelCtrl.$setViewValue(clean);
ngModelCtrl.$render();
}
return scope.hesapla(clean);
});
element.bind('keypress', function(event) {
if(event.keyCode === 32) { // space
event.preventDefault();
}
});
element.bind('keypress', function(event) {
if(event.keyCode === 45) { // - key
event.preventDefault();
}
});
}
};
})
It's working on browser perfectly but keypress event not working on the device.Tried to inspect device with google chrome but not firing. I also tried keyup or keydown but still not working. How can I get this done?
Thank you

Include jQuery Mobile file
What you need to do is just include a jQuery file into your project. A file named jQuery.mobile.js or quite similar (ex. jQuery.ui.js) of any version can help you.
You can download it from : Download | jQuery Mobile

Ionic - disable hardware backbutton in Windows Phone 8.1 not working

I'm developing using IONIC framework. I'm having trouble with the hardware back button.
In android the hardware back button works perfectly, but the windows phone did not work out.
When I use the back button on windows phone minimizes the application and returns the device's home.
This function only works on android:
$ionicPlatform.registerBackButtonAction(function () {
console.log("Not work in WP");
}, 100);
help !!

I found solution.
In site
https://www.hoessl.eu/2014/12/on-using-the-ionic-framework-for-windows-phone-8-1-apps/
have a post calling -> Not fixed yet: Back Button
Not fixed yet: Back Button
With Windows Phone 8.0, listening on the “backbutton” event was pretty
simple, just as with android. On WP8.1, this event is not triggered
anymore. I haven’t figured out how to enable it yet. Any hint would be
appreciated.
But a user commented the solution. follows the passage that worked in
my case
Back Button Fix :
Set your $ionicPlatform.registerBackButtonAction
$ionicPlatform.registerBackButtonAction(function (evt) {
if (evt && evt.type == ‘backclick’) {
$ionicHistory.goBack();
return true;
}
}, 100);
Hookin WinJS and send it to Ionic :
if(ionic.Platform.isWindowsPhone)
{
WinJS.Application.onbackclick = function (evt) {
$ionicPlatform.hardwareBackButtonClick(evt);
return true;
}
}
Easy Fix, long time figuring it out

Example for placing the code inside app.js
angular.module('starter', ['ionic', 'starter.menu', 'starter.services'])
.run(function ($ionicPlatform, $ionicHistory, $state, ...) {
$ionicPlatform.registerBackButtonAction(function (evt) {
if (evt && evt.type == 'backclick') {
$ionicHistory.goBack();
return true;
}
}, 100);
...
$ionicPlatform.ready(function () {
...
if (ionic.Platform.isWindowsPhone()) {
WinJS.Application.onbackclick = function (evt) {
if ($state.current.name == 'app.home') {
//function responsible for exiting the application in Windows phone 8.1
cordova.exec(null, null, "ExitApp", "execute", []);
} else {
$ionicPlatform.hardwareBackButtonClick(evt);
return true;
}
}
}
}); ...
$stateProvider
.state('login', {
url: '/login',
templateUrl: 'templates/login.html',
controller: 'LoginCtrl',
onEnter: function ($state, UserService) {
console.log("##### - " + UserService.get().isLogged);
if (UserService.get().isLogged) {
$state.go("app.home");
}
}
})
.state('app', {
url: '/app',
abstract: true,
templateUrl: 'templates/menu.html',

})
.state('app.secretary', {

}
})

Ext.device.notification.show creating errors in Phonegap - Sencha Touch 2

I have a Sencha Touch 2 project and everything works great in the web browser. No errors in the console, and everything looks good. Once I package it with Phonegap and run it on a mobile device, however, things don't work as well.
I am using ext.device.notification.show in two places in my application. At first, I was doing requires: 'Ext.device.*' and while it worked in web, the app wouldn't run on mobile and eclipse would give me the error message Uncaught TypeError: Cannot read property 'name' of undefined. I switched over to requires: Ext.device.Notification (exact spelling and capitalization) and now the app runs but when I click a button that should create a message box, I get the error Uncaught TypeError: Cannot call method 'confirm' of undefined. The problem is I have no method called confirm. In one case I have a method called confirmItem, but for the second button that should be invoking a message box I have no method remotely close to "confirm."
I'll post one of the controllers below (this one has the confirmItem method):
Ext.define('MyApp.controller.MainController',
{
extend: 'Ext.app.Controller',
requires: ['Ext.device.Notification'],
config:
{
refs:
{
mainView: 'mainview',
btnConfirm: 'mainview button[action=confirmItem]',
},
control:
{
'btnConfirm':
{
tap: 'confirmItem'
},
mainView:
{
onSignOffCommand: 'onSignOffCommand'
}
}
},
// Transitions
getSlideLeftTransition: function ()
{
return {
type: 'slide',
direction: 'left'
};
},
getSlideRightTransition: function ()
{
return {
type: 'slide',
direction: 'right'
};
},
onSignOffCommand: function ()
{
var me = this;
console.log('Signed out.');
loginView = this.getLoginView();
//MainView.setMasked(false);
Ext.Viewport.animateActiveItem(loginView, this.getSlideRightTransition());
},
confirmItem: function ()
{
Ext.device.Notification.show(
{
title: 'Confirm',
message: 'Would you like to Confirm?',
buttons: ['No', 'Yes'],
callback: function (button)
{
if (button == "Yes")
{
MyApp.app.getController('MainController')
.confirmPickup();
}
else
{
console.log('Nope.');
}
}
});
},
confirmPickup: function ()
{
var me = this;
var loginStore = Ext.getStore('LoginStore');
mainView = this.getMainView();
mainView.setMasked(
{
xtype: 'loadmask',
message: ' '
});
if (null != loginStore.getAt(0))
{
var user_id = loginStore.getAt(0).get('id');
var name = loginStore.getAt(0).get('name');
var winner = loginStore.getAt(0).get('winner');
}
if (winner === 1)
{
console.log('success');
}
else
{
console.log('fail');
}
}
});
I only assume this is a problem because whenever I push the button that should be calling confirmItem I get the error. Am I using Ext.device.Notification correctly, or Have I missed something needed to make it work in Phonegap?

I found the solution! Everything was fine from a Sencha Touch point of view in terms of using requires: Ext.device.Notification but some things were missing on the Phonegap side. Specifically, I needed to install the appropriate plugins.
Open a terminal and type: Phonegap local plugin list to see your currently installed plugins. I had none. I went ahead and installed:
org.apache.cordova.device
org.apache.cordova.dialogs
org.apache.cordova.vibration
by using the following reference: http://docs.phonegap.com/en/3.0.0/cordova_device_device.md.html and selecting options from the menu on the left.

Qt 5.1 Android program does not send keypresses

I am creating a program in Qt 5.1 and Qt Quick 2.0 for Android but my phone doesn't seem to send keypresses. The same code works when i run it on my desktop so the focus seems to be okay.
Both the Keys.onPressed and the Keys.onBackPressed don't work, the back key just closes the program. I am debugging on a Android 4.2 device via ADB.
Main.qml
Rectangle {
id: container
focus: true
Keys.onPressed: {
console.log(event.key)
if (event.key === Qt.Key_Backspace) {
if (rectangleDetails.visible === true) {
console.log("Left key pressed")
rectangleDetails.visible = false
listViewIndex.visible = true
event.accepted = true
} else {
Qt.quit()
}
}
}
Keys.onBackPressed: {
console.log("Back key pressed")
if (rectangleDetails.visible === true) {
rectangleDetails.visible = false
listViewIndex.visible = true
event.accepted = true
} else {
Qt.quit()
}
}
Thanks in advance

Try Keys.onReleased. This should solve your issue. See here for more information http://qt-project.org/forums/viewthread/29366
