Public methods

createIntent

added in API level 21
public abstract Intent createIntent ()

Creates an intent that would start a file picker for file selection. The Intent supports choosing files from simple file sources available on the device. Some advanced sources (for example, live media capture) may not be supported and applications wishing to support these sources or more advanced file operations should build their own Intent.

 How to use:
 1. Build an intent using createIntent()
 2. Fire the intent using Activity.startActivityForResult(Intent, int).
 3. Check for ActivityNotFoundException and take a user friendly action if thrown.
 4. Listen the result using Activity.onActivityResult(int, int, Intent)
 5. Parse the result using parseResult(int, Intent) only if media capture was not requested.
 6. Send the result using filePathCallback of WebChromeClient.onShowFileChooser(WebView, ValueCallback, WebChromeClient.FileChooserParams)
 

Returns
Intent an Intent that supports basic file chooser sources.

getAcceptTypes

Returns preference for a live media captured value (e.g. Camera, Microphone). True indicates capture is enabled, false disabled. Use getAcceptTypes to determine suitable capture devices.

boolean

parseResult

added in API level 21
public static Uri[] parseResult (int resultCode, 
                Intent data)

data Intent: the intent returned by the file picker activity.

Returns
Uri[] the Uris of selected file(s) or null if the resultCode indicates activity canceled or any other error.
