Current behavior:
When calling to file.readAsDataURL (or any other read) the promise never resolves. it happens only when running WITHOUT live reload. it happens when loading few images to the storage (to the applicationData directory) and then trying to load them and display them.

Expected behavior:
the promise should resolve or reject.

Hi,

Same issue here !

I've noticed the problem is that this is never called back when cordova FileReader is patched by zone.js

Sometimes (I can't find a way to reproduce each time) File plugin script is loaded before zone.js patch and it breaks something.

My workaround was to move cordova.js script after zone one and it seems to be working...

Hope it helps

Thanks anyway for the great job

EDIT

seems to be same problem as #1174 and ionic-team/ionic-native#505 discussion is open here ionic-team/ionic2-app-base#126

So maybe it can be closed and we'll continue on it

Thank you @paulsouche ! i moved the cordova.js after vendor.js script (in the index.html) and it did solved it.
thank you very much!

I have the same problem when i use ReadAsText method from FileReader. onloadend event does not fired. Issue starts from update ionic up to 3.9.2 version.
Fix from @paulsouche works, but it is not a right way to solve this issue.

[paulsouche]

Hi @vzharkov ,

I think we should find a solution between cordova / Zone / file-plugin on this thread

[yosigolan]

@danielsogl why do you close this? is it fixed?

[franbueno]

We are on May and it works randomly. So it wasn't fixed. Thanks @paulsouche for your workaround.

[pistou]

Yep, definitly not fixed.

[lordgreg]

should be reopen.

[CarlosAyala]

@danielsogl
Hi, this needs to be reopen. Not fixed.

[CarlosAyala]

Update cordova-android to version 7.1.1 and zone.js to 0.8.26 to fix this issue in Ionic3.

[charles-dr]

Thanks , @paulsouche and @CarlosAyala
It works like a charm!
Moved the cordova.js after the vendor.js in index.html file

You don't need to suffer if you just don't use Ionic or you will suffer from bunch of nightmares forever

[julian-bruening-wiadok]

This seems to still be an issue. Is there a workaround?
Filesytem from Capacitor is working, but I dont know how to use it with the Video Capture Plus Plugin.
