Can you reproduce this on multiple devices or versions of Android? Or only one particular device/version of Android?

The code in our control uses longs for file size, it looks there's some internal cast from long to int in the framework code.

And I'm wrong: https://developer.android.com/reference/java/nio/channels/FileChannel.html#map(java.nio.channels.FileChannel.MapMode, long, long).

Hi， sjudd,
In FileChannelImpl.map, it will check size.
If size > Integer.MAX_VALUE, it will throw exception.
It's android source code, so it can not change.
So if we want to get thumbnail for one file (ove 2GB file), how can I do?
