Hi,
I have an Ionic4 app that calls some web services using HttpClient;

import { HttpClient } from '@angular/common/http';
...
constructor(private plt: Platform, private  httpClient:  HttpClient,...) {...}
...
  login(username, password) {
    const loginUrl = this.settingsManager.getBaseWsUrl() + '/auth/login';
    return  this.httpClient.post(loginUrl, {
      email: username,
      password: password
    });
  }

I’ve tried this app, with this code on some Android devices and it works well.
It works well in debug mode with Chrome.
Now I’ve installed this app on a Huawei device (Honor Play COR-L29 with Android 9) and on this device the httpClient call fails.
I can’t see the error, so I can’t understand what is the problem.
The device is online.

I’ve installed the Ionic Dev app on this device to try the app, but I can’t login because it seems that Ionic Dev too doesn’t reach the Network.
So, is it a problem between the network plugin of Ionic and Huawei?
Do you ever had this problem?
Are there any other tests I can do to debug the problem?
I have no idea.

Thank you very much

Claudio

i was able to build fine in the morning, but when i came back from lunch, i instantly got this error.

i have tried to remove and add android back, but that was no luck.
after that i tried to add the following in my platform/android/project.properties

from

cordova.system.library.2=com.android.support:support-v4:27+

to

cordova.system.library.2=com.android.support:support-v4:27.1.0

in between building i had added file opener plugin and androidpermissions plugin, but im unsure if this would cause the problem. i have uninstalled androidpermissions and that didn’t work. i have also uninstalled the file opener but this didn’t work either.

Hi guys !

I’m implementing a simple progress bar in my Ionic 4 project, but it doesn’t progress at all while I’m uploading a file unless I click anywhere on my app.
If I don’t click, it juste stays at 0, but when I click somewhere, the progress bar gets updated so it progresses.

How to do to make it progress without clicking anywhere ?

Here’s my ts file:

export class MyUploadPage implements OnInit {

    uploadPercent: any = 0;
    videoFileUpload: FileTransferObject;

    constructor(...) {}

    this.videoFileUpload.onProgress((data) => {
          this.uploadPercent = Math.round(data.loaded / data.total);
    });
}

Here’s my progress bar:

<ion-row class="uploading">
  <ion-col text-center>
    <ion-progress-bar [value]="uploadPercent"></ion-progress-bar>
  </ion-col>
</ion-row>

Any ideas ? Thanks !

now i only have one mac and want to try ionic 4 also on ios with xcode. here is where i need a localy ionic 4 installation and no globally - so i am still able to maintenance and build the ionic 3 apps like before.

Hello,
I’m using Firebase for authentication (specifically the phone auth method),
and it’s working fine (validation etc.), except for one thing;
If the user enters the wrong code, or dismisses the validating prompt, he can’t re-enter the cycle again (prompt -> receiving message -> validate) because I can’t reset the recaptcha, and because of that he needs to reenter the app in order to reset everything.

How do I fix this ?

CODE:

html:

<ion-content padding class="popup-bg">
  
  <form [formGroup]="profile" (ngSubmit)="submitProfile()">
     ...
    <button  id="submitButton" ion-button full [disabled]="!profile.valid" (click)="submit()">submit</button>
  </form>
  <div id="recaptcha"></div>
</ion-content>

.ts:

        declare var grecaptcha: any;
...
	private _recaptchaVerifier: auth.RecaptchaVerifier;

...
	ionViewDidLoad() {
			
			this._recaptchaVerifier = new auth.RecaptchaVerifier('submitButton', {
				'size': 'invisible',
				'callback': function(response) {
					this.submitProfile()
				},
				'expired-callback': ()=>{
					this.resetReCaptcha()
				}
				
			});
		}
		
...
private submitProfile() : void{
			
			if(!this.checkPhone()){
				return;
			}
			let profile: object = {
				name: this.profile.get('name').value,
				phone: this.profile.get('phone').value
				
			};
			
			let validPhoneNumber: string =String(profile['phone'])
			//auth().settings.appVerificationDisabledForTesting = true;
			this._authAf.auth.signInWithPhoneNumber(validPhoneNumber, this._recaptchaVerifier).then(result=>{
				const alertSignIn = this._alertCtrl.create({
					title: 'enter code',
					inputs: [{type: 'number', name: 'vCode'}],
					buttons: [{text: 'validate', handler: data => {
						
						const loadSignIn = this._loadingCtrl.create({})
						loadSignIn.present().then(()=>{
							
							result.confirm(data['vCode']).then(() =>{
								this._userHandler.init();
								this._userHandler.addUser(profile);
								// this._messagingHandler.getToken();
								loadSignIn.dismiss()
							}, e=>{
								loadSignIn.dismiss()
								this.resetReCaptcha();
								return
							})	
						});
					}}
				]
			});
			alertSignIn.present();
		}).catch((e)=>{
			
			this.resetReCaptcha();
		})
	}
...

// I've tried this. not working

private resetReCaptcha(){
		this._recaptchaVerifier.render().then(function(widgetId) {
			grecaptcha.reset(widgetId);
		})
	}

hello, My app crashes when reading data from local sqlite storage. I have determined that the Select statement crashes the app when the no.of rows in the table exceeds 180,000. At this time app uses Storage of about 43Mb and memory usage is about 120MB (from app info) Select query format is 'Select col1,col4,col5 from table1 where date = date(‘2019-04-29’); In my test scenario the select query should return all the data of 180,000 rows. How do I make this perform better? I am testing the app on a Samsung Galaxy S7 with Android version 8.

Hi, I’m using Ionic 3 and for some reason when testing my app with ionic serve and using F12 to adjust the screen, I sometimes want to check the styles but the styling list shows nothing, when I add a class to something it does show and chenges it in the display but does’t display the styles in there. It only does it after I’ve cancelled the compilation with Ctrl + C and even then I’m unable to properly alter them.

Also, another problem that perhaps goes along with this one is that whenever I update my project after changing a few things it doesn’t refresh, pressing F5 doesn’t update it either, it just stays with the project it got when I compiled with ionic serve, I have to cancel it and recompile it to see the changes, it’s tiresome working like this, perhaps these 2 issues are related?, yeah they do happen in the same project:

Hi there,

somehow I need to get the name of the last shown page.

There are three pages: Page one, two and three.

Starting at the first page, I click around over the second straight ahead to the third page. When I go back from the third page to the second page, either by clicking on back in html, calling navCtrl.back() or pushing the smartphones back button, I need to know at the showing state of the second page, if the last page was the first or third page. It’s that simple.

I cannot use the way over GET-parameters in the calling route path for the second page, when pushing any back buttons. A way over a singleton/service is imaginable, but isn’t there an eleganter way?

Best regards
Sue

Hey,
we are in the middle of developing and testing our app on various devices and encounter an issue with android:

The ionic app doesnt expand to the areas next to a “notch” or a non present toolbar at the bottom.

ios handles it quite well:

Screenshot 2019-05-02 at 19.29.23.jpg842×1716 96.3 KB

The upper area besides the notch stays black (iOS iphone x handles it quite well and styles the area)
The lower black bar is where the deactivated toolbar would be i guess.

How can i make my android app behave like on the iPhone X where all these areas are covered properly?

Thanks for any hints/advice!

Hi all!

I’ve used Ionic in the past, but only for mobile alone. I’m about to start a new project and am still in the decision-making process of choosing frameworks and Ionic is the plan as of now.

My problem is that I don’t know if it’s suitable to use Ionic alone for this project, or if it complicates things for the desktop-development. I know Ionic supports desktop, but I don’t want it to be a struggle compared to building pure desktop outside of Ionic.

The app I’m building will be targeting desktop in the first hand, but we think a great portion of our users will use it directly in their mobile browser, which is why we’re considering Ionic. We do not have any plans on releasing it as an app in the stores, since we don’t require any native functionality at all.

So, I’m leaning towards these two options, and would love your guidance on this:

1.) Build everything in Ionic, even if the main-target is desktop-browsers
2.) Build the desktop-browser part outside of Ionic (in pure Angular), but with a shared code-base that extends to our Ionic app which will be used for mobile. So in reality two apps but with shared code in-between.

My main concern is that option 1 will complicate things, compared to running Angular alone, since Ionic is built for mobile in the first place.

Thanks for your input!

Hi,
I’m developing an Ionic4 app.
I can see that if you create a new brand app the components the @ionic-native components are at the version 5.0.0.
For example:
"@ionic-native/core": "^5.0.0",

I can see that all these components are upgradable to the version:
"@ionic-native/core": "^5.5.1",

Since I have some problem with the @ionic-native/barcode-scanner I don’t know if I should upgrade all the @ionic-native components to the last version.

So the question is when we should upgrade our @ionic-native components?
And should they be all to the same version?

Thank you very much
