Add support for Android AAssets mapping #17

Open jherico opened 6 years ago

vimpunk commented 6 years ago

I don't have experience with Android programming, so I'm a bit lost as to what this is (and unfortunately a quick search didn't yield me anything concrete). Could you please provide me with some additional info?

In addition to the normal filesystem on Android, there is an asset filesystem whereby applications can access read-only resources that are embedded in the APK.

There is an overview of the API here. Assets can be opened as a file descriptor, or they can be opened simply as a buffer, where you get back a const void* to the contents of the asset.

Thanks for the update. If assets can be opened as a file descriptor, could mio not be used as is, passing the descriptor to the constructor/mapping function?
