The default Android camera application returns a non-null intent only when passing back a thumbnail in the returned Intent. If you pass EXTRA_OUTPUT with a URI to write to, it will return a null intent and the picture is in the URI that you passed in. You can verify this by looking at the camera … Read more
It’s easier than the other response. There is an xml value alpha that takes double values. android:alpha=”0.0″ thats invisible android:alpha=”0.5″ see-through android:alpha=”1.0″ full visible That’s how it works.
This isn’t a direct answer to the question (loading images >2048), but a possible solution for anyone experiencing the error.

There’s no differences, except default style. ImageButton has a non-null background by default. EDIT: Also, ImageButton.onSetAlpha() method always returns false, scaleType is set to center and it’s always inflated as focusable. Here’s ImageButton‘s default style: <style name=”Widget.ImageButton”> <item name=”android:focusable”>true</item> <item name=”android:clickable”>true</item> <item name=”android:scaleType”>center</item> <item name=”android:background”>@android:drawable/btn_default</item> </style>
