The loop extracted keys from `folderMap` and then called
`folderMap.get(...)` for every key. If both the key and the value needs
to be iterated on, `Map.entrySet()` is a more efficient solution as it
doesn't require O(n) Map lookups.
Since id is a Long, Long.valueOf(long) unboxed the Long to a primitive
long, then reboxed it into a Long instance, which was again unboxed to
allow it to be set as an element of the array of longs. This commit
reduces the number of boxings from 3 to 1.
Under certain circumstances it's possible that the 'push state' isn't
updated to contain the most recent 'UIDNEXT' value. In that case
ImapFolderPusher.start() would execute the same code path through its
main loop over and over again, preventing the device from going to
sleep.
Rather than changing the code to update the 'push state' in the corner
case that triggers the behavior described above, this commit introduces
another mechanism to track the 'UIDNEXT' value. This should also catch
as of yet unknown cases where the 'push state' isn't properly updated.
At some point in the future I hope we get to a point where we only
persist the 'push state' when we manually stop/restart the service.
During normal operation there's no need to read from/write to storage
all the time.
Fixes issue 4907
When message viewing and tap the next icon, menu icons (previous, next, delete and replys) disappears for an instant.
But a compose icon remains, then tap it accidentally.
Eliminate the invocation of
WebSettings.setBlockNetworkImage(boolean flag),
thus maintaining the the default setting of "false".
On Android versions prior to KitKat, this setting has no
effect on inline image attachments loaded with content:
URIs. Such images would load regardless.
With KitKat, this setting does have an effect -- a
setting of "true" will block image attachments loaded
with content: URIs.
By removing this call, K-9 Mail behaves the same on KitKat
as on earlier Android versions, and the behavior on earlier
versions is unchanged.
The minSdkVersion was recently increased from 8 to 15.
WebSettings.setBlockNetworkLoads has been publicly available
since API level 8 (Froyo).
StrictMode has been publicly available since API level 9
(Gingerbread).
