Public methods

createIntent

Added in API level 21
abstract fun createIntent(): Intent!

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 android.app.Activity#startActivityForResult.
  3. Check for ActivityNotFoundException and take a user friendly action if thrown.
  4. Listen the result using android.app.Activity#onActivityResult
  5. Parse the result using parseResult only if media capture was not requested.
  6. Send the result using filePathCallback of android.webkit.WebChromeClient#onShowFileChooser
Return
Intent! an Intent that supports basic file chooser sources.

abstract fun getAcceptTypes(): Array<String!>!

The file name of a default selection if specified, or null.

Added in API level 21

Added in API level 21
abstract fun getTitle(): CharSequence?

Returns the title to use for this file selector. If null a default title should be used.

Added in API level 21
abstract fun isCaptureEnabled(): Boolean

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.

parseResult

Added in API level 21
open static fun parseResult(
    resultCode: Int,
    data: Intent!
): Array<Uri!>?

Parse the result returned by the file picker activity. This method should be used with createIntent. Refer to createIntent for how to use it.

data Intent!: the intent returned by the file picker activity.
Return
Array<Uri!>? the Uris of selected file(s) or null if the resultCode indicates activity canceled or any other error.
