You’re right. I just tried to create a new project and the error appeared.

As soon as I add this: yarn add @ionic/vue
And update the main.js file.
The error appears.

I don’t know what to do.

the problem may be because you are generating multiple <ion-content> tags. There should be only one per page: https://ionicframework.com/docs/api/content

Hope this helps.

This helped me a lot. I will post here my code with a function that check if device is using cordova, check if a dir already exists, check if file already exist and then save the file. If device is not using cordova, it will save the file using other method (for browsers). I made some changes as my function already receive the data formatted for my desired format, GeoJSON. Another thing that I changed was the version of File Transfer plugin, now using the updated method/version. This don’t get the file from any server, the data “downloaded” is already on device, I hope this helps someone:

fileTransfer: FileTransferObject = this.transfer.create();
download(file, name) {
	if (this.platform.is('cordova')) {
		this.file.checkDir(this.file.externalRootDirectory, 'downloads')
		.then(
			// Directory exists, check for file with the same name
			_ => this.file.checkFile(this.file.externalRootDirectory, 'downloads/' + name + '.geojson')
			.then(_ => {alert("A file with the same name already exists!")})
			// File does not exist yet, we can save normally
			.catch(err =>
				this.fileTransfer.download(file, this.file.externalRootDirectory + '/downloads/' + name + '.geojson').then((entry) => {
			    	alert('File saved in:  ' + entry.nativeURL);
			    })
			    .catch((err) =>{
			    	alert('Error saving file: ' + err.message);
			    })
			))
		.catch(
			// Directory does not exists, create a new one
			err => this.file.createDir(this.file.externalRootDirectory, 'downloads', false)
			.then(response => {
				alert('New folder created:  ' + response.fullPath);
			    this.fileTransfer.download(file, this.file.externalRootDirectory + '/downloads/' + name + '.geojson').then((entry) => {
			    	alert('File saved in : ' + entry.nativeURL);
			    })
			    .catch((err) =>{
			    	alert('Error saving file:  ' + err.message);
			    });
		
			}).catch(err => {
				alert('It was not possible to create the dir "downloads". Err: ' + err.message);
			})			
		);			 

	} else {
		// If downloaded by Web Browser
		let link = document.createElement("a");
		link.download = name + '.geojson';
		link.href = file;
		document.body.appendChild(link);
		link.click();
		document.body.removeChild(link);
		link = null;
	}
}

How do i solve this problem?

Muito obrigado, isso resolveu p/ mim

I want to have classic style of select box so I use

<select class="box" name="al">
            <option value="all">all</option>
            <option value="a">A</option>
            <option value="b">B</option>
        </select>

but in this case…how can I detect value is selected?
I don’t think I can use jquery…

I still don’t understand why ion-select is too much different than classic select box…
I don’t want to select any value from popup when I use selectbox.

Thanks a lot, @boltex, it seem really a solution.

I’m listing the devices of my phone in a ionic 4 app using Angular7 and cordova. Calling navigator.mediaDevices.enumerateDevices() I got all audioinput and videoinput but the labels are empty. I know I have to call to this method when the audio and video permissions are granted and I do that.

Connecting to a webrtc sample through Android browser works but through Android WebView not.

Why the labels are empty? How can i list all devices of my android phone?
Thanks

Hi all I’m picking up an old Ionic 1 project from a couple of years ago. To keep our app in the Google play store I need to somehow generate a 64 bit APK. I’m a little lost on how to do that - I’ve not touched ionic for the last 2 years and a hell of a lot has changed.

I’ve got a couple of questions,

1. is crosswalk still needed? It looks like that plugin (or atleast the version of cross walk I have installed includes some .so files which will apperently prevent a 64 bit version?
2. I don’t seem to be able to reinstall all my plugins. I’ve tried ionic state reset but apparently that’s been removed in CLI 3. I’ve tried ionic cordova prepare but I get Error: Your MyApplication platform does not have Api.js…
3. What CLI version should I be running to build an old ionic 1 app, bearing in mind I need to generate a 64 bit APK.

If anyone could help or point me in the right direction that would be awesome.

ionic info gives me:

cli packages: (/usr/local/lib/node_modules)

    @ionic/cli-utils  : 1.19.1
    ionic (Ionic CLI) : 3.19.1

global packages:

    cordova (Cordova CLI) : 7.0.1

local packages:

    Cordova Platforms : android 5.1.1 ios 3.9.2
    Ionic Framework   : ionic1 1.1.1

System:

    ios-deploy : 1.9.1
    ios-sim    : 5.0.13
    Node       : v8.11.3
    npm        : 5.6.0
    OS         : macOS High Sierra
    Xcode      : Xcode 10.0 Build version 10A255

Environment Variables:

    ANDROID_HOME : not set

Misc:

Thanks in advance

@pantarmj Maybe this can help you (I haven’t implemented it myself):

Hello,

I am currently developing an application with Ionic. I use for this, a model of the application to do the same, with colors, fonts (in px), image, etc …

My question is, should I use the EM or PX unit for the font ?

I ask myself this question because for me the unit EM is supposed to be more adapted to all types of screen. However, the fonts transmitted with the models are in PX and therefore more complicated to make a model identical with the EM unit.

I would just like to know if the EM unit is really useful or not, using Ionic.

Thanks for your help

We have same problem. And its big trouble now. The app is working since 2 month on android and on iOS we can not get it though the test in Appstore.

Hello,

I have the same problem. I tried with ionViewWillEnter but doesn’t work.In the page A I put the method ionViewWillEnter with a console.log(). In the same page I have a button with the atrribute routerLink="/pageB". In pageB I put the back button . When I come back to the page A, the console.log doesn’t print.

Anyone know what is my problem? I’m new on ionic/angular

Thank you!
