How do I change the color of the StatusBar text in the versions before?

and ` this.platform.ready().then(() {

this.statusBar.overlaysWebView(true);
this.statusBar.styleDefault();
(window as any).StatusBar.styleDefault();
this.statusBar.backgroundColorByHexString(’#fff’);

      {"value": "Open", "onclick": "OpenDoc"},

    export interface Menuitem {
        value: string;
        onclick: string;
    }

    export interface Popup {
        menuitem: Menuitem[];
    }

    export interface RootObject {
        popup: Popup;
    }
}

what should i write in success funtion so the above response convert automatically into Example.ts

$.ajax({
               url:'URL',
                      type: "GET",
      success : function(responseText)

      },
    error: function(XMLHttpRequest, textStatus, errorThrown)

Hi,

I have a problem with ionic version 4.rc-0 and tab-bar position.
Every thing is correctly displayed when you add directly or

But if you want to be dynamic like :
<ion-tab-bar [slot]=“tabplacement”>
(tabplacement is changed in the constructor)
it always display the tab bar at the bottom.

I tested it with the tab starter in ionic cli.

Any idea to correct this ?

Thank you !

Hi,

I’ve a page with a custom back button to show a confirmation box if this user is sure they want to go back cause they’ll lose data. However i can still swipe from left to right to go back and i can’t seem to capture this event nor can i disable it on this page alone.

I was wondering if anybody had any idea how to achieve this.

With best regards,

Good Morning,

I am new with regards to the development of ionic and I want to develop a project but I am confused whether to do it in ionic 4 beta or in its version 3, I would like you to recommend which version you should use.

also if using version 3 and update the project to version 4 when it is officially released, it could be done without problems

Thanks

Hello

Recently for some errors that show me in project I decide star a new project from scratch,

After creating the project with ionic start myApp tabs --type = angular (I have created it in two diferents computers and the same thing happens to me)
I get a message that there is a high severity vulnerability, I execute the command suggested by npm audit fix, but it does not fix it and says to do it manually, the problem is with some webpack-dev-server. Should I worry? How do I fix it?

2019-01-03_16-32-31-f61a31732efefae5daf8393a7bb8b3a8.jpg1228x889

The second question is: When I get these Warnings, when I’m installing a native Api, what should I do? It says that it requires certain libraries. Should I install them? How do I install them?

Thanks for advance

Hi there. I’m having some trouble to use the ECMAScript Internationalization API.

Initially on my project I’ve used the Globalization API from ionic, cordova which worked fine. While trying to lint my project I’ve got the following error

WARNING: […]: Globalization is deprecated: With the ECMA Internationalization API now supported on iOS, Android and Windows devices, this plugin is not required any more.
Migrating from this plugin to the ECMA Internationalization API is explained in this Cordova blog post.

I’ve read the migration post, which seems rather simple. By just using the navigator which is a global variable then you can make use of the globalization functions, such as the getPreferredLanguage function which I’m interested on for initializing the language based on the device (mobile or browser) locale. There doesn’t seem to be any extra configuration.

But then while trying to compile I’m getting

error TS2339: Property ‘globalization’ does not exist on type ‘Navigator’.

This seems rather strange to me, I’ve installed the “cordova-plugin-globalization” plugin on my package.json, also on my config.xml file and then both my andorid.json and browser.json files in the plugins folder. Yet this isn’t detected. I’ve tried to overpass this error while compiling by doing something like

let nav: any = (navigator as any);
if (nav.globalization) {
    nav.globalization.getPreferredLanguage(
         (res) => {
                console.log('globalization lang ', res);
          },
          (error) => {
                console.error('error ');
          }
    );
} else {
     console.log('no globalization');
}

but this always evals to ‘no globalization’. Does someone stumbled with this problem or knows a possible solution?

Good morning people and good year, I am with a problem that I have been carrying for weeks and he looked for many solutions for all Google and none works for me, since I ask you to forgive me for my bad English! I tell them maybe someone can help me:

I am in a phone tracking system that works perfectly with ionic 3.9.2 and observe the follow-up with the angular angle in the latitude and longitude of the data that the application sends a firebase, until then everything is great. But I have a small problem when it comes to the application work in the background, I have installed background mode, background geolocation and powermanagement and this happens to me:
Lock the phone with the lock button and send the coordinates a firebase for no more than 2 min.
If I refer to a middle button that is in the background, it directly stops me from passing the coordinates.
What I need is to be able to use the phone normally and the application.

I hope you have explained me well!
Thanks and I hope someone has already gone through this and you can help me!
Thanks again !!
