164 // If |multiSelect| is true, the dialog allows to select multiple
165 // files.
166 // |initialValue| is a filename which the dialog should select by
167 // default. It can be an empty string.
168 // |selectedFiles| has filenames which a file upload control
169 // already select. A WebViewClient implementation may ask a user
170 // to select removing a file from the selected files, appending
171 // other files, or replacing with other files before opening the dialog.
172 // |acceptTypes| has a comma-separated MIME types such as
173 // "audio/*,text/plain". The dialog may restrict selectable files
174 // to the specified types. This value comes from an 'accept'
175 // attribute value of an INPUT element. So it might has a wrong
176 // formatted string.
