Answer 1

The answer by Riad points into the right direction, but that single callback is not enough to implement.

There are, in total, four hidden API methods that you have to implement. Their usage depends on the Android version. These methods are:

public void openFileChooser(ValueCallback uploadMsg)
public void openFileChooser(ValueCallback uploadMsg, String acceptType)
public void openFileChooser(ValueCallback uploadMsg, String acceptType, String capture)
public boolean onShowFileChooser(WebView webView, ValueCallback filePathCallback, WebChromeClient.FileChooserParams fileChooserParams)

You can use the following library which does all these things for you:

Alternatively, you may take a look at the source code to see how it's done:
