Preventing the Android "long press" to save images

Question

I've written a web-app in HTML and Javascript for iPhone and Android which involves the dragging and dropping images.

You initiate the drag by holding your finger over the image for about a second. However, Android then pops up the message giving me the option to save the image, set it as wallpaper etc.

How can I prevent Android from doing this? Is there a metatag I can use? Some javascript?

Answer 1

Javascript has a function to prevent the default action of a browser for the event in question.

In your javascript try:

event.preventDefault();

See: https://developer.mozilla.org/en/DOM/event.preventDefault

Answer 2

In your activity that shows the webview, try extending GestureDetector.SimpleOnGestureListener. Then override the onLongPress(MotionEvent e) method and doing nothing.

If that doesn't work, you might have to create a custom webview that inherets from webview and overrides onLongPress there.

Or maybe you could try

WebView wv =(WebView) findViewById()
wv.setClickable(false)
