Remarks
Callback that handles file system requests from ProxyFileDescriptor.
All callback methods except for onRelease should throw android.system.ErrnoException with proper errno on errors. See errno(3) and android.system.OsConstants.
Typical errnos are
<ul> <li>android.system.OsConstants#EIO for general I/O issues <li>android.system.OsConstants#ENOENT when the file is not found <li>android.system.OsConstants#EBADF if the file doesn't allow read/write operations based on how it was opened. (For example, trying to write a file that was opened read-only.) <li>android.system.OsConstants#ENOSPC if you cannot handle a write operation to space/quota limitations. </ul>
