Ionic Pro: App does not load on the Ionic View app

I created an ionic 2 pro app that works fine on browser (localhost:). It also works fine when I create an apk out of it (using “ionic cordova build android”) and install it on my android.

However when I try to open it in the Ionic View App (both android and iphone), the app doesn’t work - I get the following errors

A white screen with this tiny message on the top - “Error 404, File not found” and in another one I get
"Wrong type of parameter “source” of Expected String, but got Undefined"

Can you please help me preview my app on the ionic view app so that I can share it with others?

i have the same problem but only with android app.

I have the same problem. Works locally and in the iOS Ionic View. Did you find any solution for it?

Update: I went into the Ionic Dashboard to the last build and took Package. From there I selected Android and clicked Package Build.
When it was done I could start it from Ionic View. Apperently I only package the iOS version.

I raised an issue with the ionic team and they recognize it as a bug (at least for Android). They said they have opened an internal ticket and will look into it.

I haven’t heard back from them since then.


I have the same issue. I hope about the fix

Currently having the same issue with ionic 4 beta. Anyone able to find a work around? I want to test the app properly before Ionic view gets canned. Thx
