* If there's a new message notification, keep showing the "New messages
in" content text, even after a disconnect notification.
* Handle the case of a channel/query name duplicated between two or more
connections more gracefully in new message notifications
* Fix a race in updating notifications
(1) Let full-screen IMEs wrap the text into multiple lines instead of
making the text scroll off the screen.
(2) Provide a preference to let the user choose whether or not to enable
autocorrection of typed text.
(3) Provide a preference to let the user choose whether or not to enable
autocapitalization of sentences. Note that even when this is enabled,
autocapitalization will only happen if the option is also enabled in the
IME.
(4) In landscape mode only, don't replace the Enter key with a Send
button, to make it harder to accidentally send a message. (We can't do
this in portrait, because we would be left without any send button at
all -- perhaps the input line should be changed to be similar to the
text message application, which has a send button next to the input
line?)
The current method of supplying an onKey handler for the input line
(having the activity implement OnKeyListener) is somewhat unusual -- the
documentation recommends creating an anonymous inner class to pass to
setOnKeyListener(). Do this, while refactoring the code to make it
somewhat more readable and removing some instances of code duplication.
Features:
* Now displays the number of mentions that the user has not seen in the
notification.
* When no mentions are outstanding, display which servers the user is
connected to, not the last message.
* When more than one mention is outstanding, display the names of the
conversations with new mentions, not just the last message received.
* Notifications of mentions are suppressed if you're in the conversation
at the time of the mention.
* Notifications of mentions automatically clear when you bring up the
conversation.
* Vibrate notifications now generate the user's chosen default vibrate
pattern, not a hard-coded one.
* Add ticker text to the notification that's displayed when the IRCService
goes into the foreground, instead of displaying a blank ticker.
To allow for all of this, the implementation moves most of the details
of generating the notification text into the IRCService, which now
exposes addNewMention() and notifyConnected()/notifyDisconnected()
methods instead of the lower-level updateNotification().
As of now, the activity does not remember whether a conversation is
switched across configuration changes (such as screen rotations). Fix
this by adding onSaveInstanceState() and onRestoreInstanceState()
callbacks in the activity to pass this information to the new instance.
To make the implementation of this simpler, all code to configure the
MessageListView, which was duplicated in several places in the codebase,
has been moved to the MessageListView's constructor.
While we're at it, make the padding setting independent of screen
density instead of specifying in fixed pixels (equivalent to specifying
the value in dp instead of px), and increase the padding for switched
views. This ensures that message text isn't obscured by the gradient at
the edges of the ConversationGallery, which started happening when we
began caching MessageListViews in the DeckAdapter.
There are at least two significant memory leaks in Yaaic, which cause
the client to force close after a few hours with an
OutOfMemoryException:
(1) The IRCService holds Conversation objects, which contain a
MessageListAdapter, which have references to the ConversationActivity
context. This causes Activity contexts to outlast the Activity, causing
a significant memory leak over time.
Fix this by holding the MessageListAdapter in the ConversationActivity's
DeckAdapter instead of in the Conversation objects. The DeckAdapter's
lifecycle matches that of the Activity, so this prevents the leak.
(2) Every call to DeckAdapter.getView()/renderConversation() creates a
new MessageListView and adds it to the deck. But adding the view to
the deck causes the deck to take a reference to the view, leaking the
MessageListView until the Activity is finished. (This has the effect of
exacerbating the first leak, since the Activity context holds a
reference to the deck.)
Fix this leak by caching MessageListViews in the DeckAdapter, and
returning an existing MessageListView for a Conversation in getView() if
one already exists.
This has two advantages:
(1) The activity remembers which conversation was last selected if it's
destroyed (e.g. via the Back button) and then recreated with the connection
still running.
(2) It prevents onCreate() from clearing all the mentioned notifications for
the conversations in that activity.
This makes it easier to ignore unintersting messages wihout turning off the setting to show joins/parts/quits.
Once circle is colored for a new message, the join/part/quit cannot override it anymore.
