A retry policy implementation that doubles the amount of time in between retries.
If downloading hasn't finish within given amount of time, this policy give up and the
EmojiCompat will get into LOAD_STATE_FAILED state.
Called each time the metadata loading fails.
This is primarily due to a pending download of the font.
If a value larger than zero is returned, metadata loader will retry after the given
milliseconds.
If zero is returned, metadata loader will retry immediately.
If a value less than 0 is returned, the metadata loader will stop retrying and
EmojiCompat will get into LOAD_STATE_FAILED state.
Note that the retry may happen earlier than you specified if the font provider notifies
that the download is completed.
