WebChromeClient.FileChooserParams.ParseResult support multiple files #15341
Comments

For any other poor soul out there struggling with this, I will post an answer to my own question. So apparently when multiple items are selected for upload the returned intent data has information in the ClipData property instead of the Data property. From the examples I posted earlier, you can change the OnActivityResult function, implement the following instead of just calling WebChromeClient.FileChooserParams.ParseResult to get the returned value. I left all of the fully qualified names of everything below for clarity. Java.Lang.Object? returnedValue; } |

i am a poor soul and you dont alone.if you choose one file the data property is not null and if choose multiple clipData is not null |

Hi BobbyShoe, I managed to get a returned value from clipdata but I am clueless as to what to do next, can you assist |

This is ridiculous that this API works this way to this day. Here's a Kotlin version val data: Intent? = result.data
val returnedValue: Array<Uri>? = if(result.resultCode !== Activity.RESULT_OK) {
null
} else if (data?.clipData != null) {
// The files are in data.clipData if the user selected multiple files
// https://github.com/xamarin/Xamarin.Forms/issues/15341
(0 until(data.clipData!!.itemCount)).map { data.clipData!!.getItemAt(it).uri }.toTypedArray()
} else {
WebChromeClient.FileChooserParams.parseResult(result.resultCode, data)
} |
Description
When trying to upload files from a WebView using an HTML input file field the WebChromeClient.FileChooserParams.ParseResult method returns null when multiple files are selected. It does work with a single file.
Steps to Reproduce
This article nicely outlines all of the steps necessary to make the File selector appear when a input file is clicked on a web page within a WebView on Android

This does work for single file selection.
To attempt to select multiple I added this Extra information in the OnShowFileChooser method, just before the call to start the activity.
chooserIntent.PutExtra(Intent.ExtraAllowMultiple, true);
The file selection Activity does allow for multiple files to be selected. However on the callback the WebChromeClient.FileChooserParams.ParseResult method does not properly parse the multi-selection and returns null.
Expected Behavior
Multiple files should be able to be selected.
Actual Behavior
Multiple file selection does not work.
Basic Information
Environment
Show/Hide Visual Studio info
Workaround
Nothing simple.
