Karen Tran closed CB-9314.
--------------------------
Resolution: Not A Problem
Closing because this ended up not being a problem. Someone else had
cherrypicked something that was causing the error in our cordova branch.
> Reading input element using filereader.readAsDataURL returns FileNotFound
> Exception
> -----------------------------------------------------------------------------------
>
> Key: CB-9314
> URL: https://issues.apache.org/jira/browse/CB-9314
> Project: Apache Cordova
> Issue Type: Bug
> Affects Versions: 3.4.0
> Environment: Android 5.0
> Reporter: Karen Tran
> Labels: FileReader.readAsDataURL
>
> Added a simple FileReader to index.html to select an image and display it,
> but always errors out.
> Expected:
> - Click 'Choose File' button
> - Select an image file
> - Get 2 alerts, 1 for entering the Openfile function, and the second for
> entering Onload
> - Image should display
> Actual:
> - Never gets to the Onload function, so image doesn't display
> - Goes to onError
> I have traced through the native side in CordovaActivity and
> CordovaChromeClient and it seems to get the result URL fine, but when it
> returns to the javascript side, the result ends up being null. I'm not too
> familiar with how the bridging works, so maybe there is some type of
> disconnect there.
> In the log, I am using the Cordova File plugin, but the issue still occurs
> even if I am not using the plugin. Everything is the same with or without the
> plugin, native side gets the result, but javascript side gets null.
> {code}
> <input type='file' accept='image/*' onchange='openFile(event)'><br>
> <img id='output'>
> <script>
> var openFile = function(event) {
> alert("Inside Openfile Function");
> var input = event.target;
> var reader = new FileReader();
> reader.onload = function(){
> alert("Inside Onload Function");
> var dataURL = reader.result;
> var output = document.getElementById('output');
> output.src = dataURL;
> };
> reader.onerror = function() {
> console.log('An error occurred while reading a file.');
> console.log(reader.error);
> };
>
> reader.readAsDataURL(input.files[0]);
> };
> </script>
