hey all,

I’m trying to run a blank ionic 4 app (angular) and it takes more than 60 seconds to initial load and also and reloads after doing changes.

I would expect this is not to be the normal case and wanted to know if anyone else is also seeing the same. And if this is a know issue, any fix. I had a quick search and couldn’t find anything related to ionic4

Following are my ionic info

Ionic:

   ionic (Ionic CLI)             : 4.5.0 (/usr/local/lib/node_modules/ionic)
   Ionic Framework               : @ionic/angular 4.0.0-beta.17
   @angular-devkit/build-angular : 0.10.7
   @angular-devkit/schematics    : 7.0.7
   @angular/cli                  : 7.0.7
   @ionic/angular-toolkit        : 1.2.0

System:

   NodeJS : v8.10.0 (/usr/local/bin/node)
   npm    : 6.5.0
   OS     : macOS High Sierra

and I can see the following in my command line

hi, I am using ionic 3 and testing on Android 6.0 - Samsung Galaxy S7.

I added the native plugin ("@ionic-native/background-mode": “^4.17.0”) to my app and it is working as expected when app goes into the background and comes out again.
But, I see the following behaviour as well- couple of pages on my app request permissions from the user when they run the app the first time after installation - to use location when user tries to scan for bluetooth devices (plugin ionic-native/bluetooth-serial": “^4.5.3”) and read/write permission when they write a file to the phone (ionic-native/file": “^4.7.0”).

After adding backgroundmode plugin the app goes into background when the permission modals open for location and file writing.

I am listening to these events-

this.backgroundMode.on(“activate”)
this.backgroundMode.on(“deactivate”)
this.backgroundMode.on(‘failure’)

Thank you so much for reading. If you need more information about my setup please ask. Any help is appreciated. If this is a bug, how do I report this? Cheers!

Hello,

In a part of my app, I have to get html content from web service and put it on the screen. The content come from the service usually contains p, img and h tags.
I did this part with [innerHTML] attribute. But when I want to use Image Viewer, it didn’t work.
I tried the package without innerHtml. It worked.

So how can I use Ionic Image Viewer with innerHtml?

I tried Pipe but it didn’t work for me.

Sample content:

<p>Title</p>
<img src="www.site.com/image.png" imageViewer />

Html file:

<ion-content padding>
  <div [innerHTML]="content | safeHtml"></div>
</ion-content>

Typescript file:

this.http.get('http://myurladdress.com/', {}, {})
    .then(data => {
      this.content = JSON.parse(data.data);
    })
    .catch(error => {

I’ve downloaded and installed Python on my machine, added it to the path and it doesn’t make any difference. I might find a solution to this by messing around but I’m documenting it for newcomers to Ionic. If you follow the “getting started” procedures on the Ionic page, this should work out of the box and not require any messing around. I’ve been working on an app since Ionic v1 and rebuilt it many times (currently rebuilding it in the latest Ionic v4) so I don’t know what my old machine has installed to fix this problem anymore. What does a new machine need to have installed to make this work?

I’ll try rolling back to node 10 first and see what that does.

I want to prompt the notification after 1 sec. How can I do it ?

Hi. I have an app that builds fine as a Package on the Ionic site. The IPA runs fine on iOS. But when I install the APK on my Android device it fails. It seems to load the app and then clearly something breaks it as it just halts.

The app runs fine when using “ionic serve”. It also runs fine on Android through the Ionic Dev app. It’s only when I compile the APK that it has problems.

I am running Linux and don’t have Android studio installed (and I’d really rather keep it that way).

Is there any way I can get feedback about what is causing the app to fail?

Thank you!

Hi there, I get this error anytime I try to run my app on an android emulator or device.

image.png1046x194 24.7 KB

From looking it up online its likely something to do with my java versioning… but on my Mac I’m really not sure how to resolve.

I’ve now downloaded a correct java version (I think), but I’m not sure how to point JAVA_HOME to it.
Ive also tried deleting Java and reinstalling but cordova seems to still be pointing at the wrong version.

Please help as I now cannot continue the development of an app

Many thanks!

I have used ionic 1 and 2 and had no trouble with compiling for iOS on XCode and Android on Android Studio on macOS. I have every package available from the Google repositories installed on my Android/sdk and I cannot get either ionic 3 or ionic 4 apps compiled on Android Studio 3.2.1 and I’m getting quite frustrated as I have been working on this for about a week. I have zero problems with either 3 or 4 and XCode. I have hacked at the files to try to get a working gradle wrapper. Now I’m getting mips library message and nothing I do fixes the issue. I have overwritten the build.gradle file with one that works fine on native Android apps. I know my Android environment works. When opening an ionic android platform it also messes with my Android Studio Tools menu and the AVD Manager and SDK Manager options go away. I’m sure I can make it work with some file removal and fixing things myself. I have a lot of web sites in Angular 4 with Bootstrap 3.3.7 and I would really like to be able to use ionic, but right now, it looks like I may have to go back to Xamarin Forms apps that work fine with VS 2017 for Mac.

Even my wife likes the ionic sidemenu apps better than my Xamarin work, and so do I.

But if ionic apps won’t work on Android natively, and not using Ionic DevApp, I will have to abandon ionic … probably for good.

hello to all, my problem happens when I implement the update of the profile image in my application, the first time it does the user changes the default image and places the one I previously loaded, but if the user tries to change the image again, still shows the previous one, what happens is that the server saves the image with the “id” of the user therefore the route does not change I think that is why the new image is not updated in the view, or I do not know if be cache problem.

Right now we have a multi-select box. They wanted some way to add a select all to it.
I knew the select box used some alert values so my original idea was to add a third button that would toggle the list, either select them all or deselect them all.

Not as easy as I would like. Even though the documentation for ion-select does say it uses the options that alert controller has, there is no way that I can see to add or even change the buttons. (only the title).

Next is adding in an extra row with this.
(ionSelect)="selectAll($event)

As far as I can tell this only gets called when the checkbox is being checked, when it gets unchecked it doesn’t fire.
Is there an easy way to do this?

WifiWizard2.conect ();

but now with ionic4 this is not so.

can someone help me to know how to use WifiWizard2 on ionic4?
