Frameworks: Slim recent app screen

One of the parts on AOSP google missed to update/improve in the last
couple of releases is the recent app screen to allow better and faster
multitasking. I had always a special vision how it could/should look
and gives the user a faster workflow.

This commit is now our new recent screen. It is a complete new implementation
and replaces googles AOSP recent app screen. The code changes in the base itself
are quiet miniml to call the new recent screen.

Some notes:

1. This patch needs a new repo: frameworks_opt_cards which is a central repo
   to get any kind of googles cards style. Thanks Gabrielle Mariotti a ton who
   made the base for this library and hellped a lot out.  We just fixed together with him some parts
   and mad it useable as AOSP central library. So we can use it later for other
   changes as well

2. Preload needs to work 100%. So it is needed to check that the calling parts
   (like hw key rebinding, pie, navigation bar) do a proper preload. If they do not
   recent screen will just not show up. To follow what they are doing you can enable
   debug in RecentController.java which exactly shows what was called.

Some notes to the patch itself:

- Recent app  screen slides from the right edge into the screen

- Show recent apps in new google card style. Most recent apps show
  expanded with the app screenshot. Other are collapsed. Of course
  the user can change expanded/collapse of each app during the session where the state
  will be restored on next access.

- Compared to AOSP recents we do a 3 stage loading
  1. step: preload the task list and build or update the cards (does not load any content at this point)
  2. step: User actually toggled the recent screen....icons, text and screenshot thumbnail which will get visible are loaded now
  3. step: Recent screen is fully animated in. All other non visible content at this time are loaded now.
  This allows a smooth experience for the user and a minimal load on the first 2 steps. Especially important due that we handle
  a lot animations which are very picky when it comes to background loads. last 2 steps are async multithreaded loading tasks.

- We are using for the app icons and thumbnails a bitmap LRU cache controller to have fast access to the bitmaps we need. This improves especially
  the scrolling and as well the loading time due that allready loaded app icons are holded in the LRU cache.

- Theme support is included as well for all items the recent screen has

- Most important point: Way faster workflow now. The recent screen neither freezes the underlaying app nor it does interrupt the current process the
  user is in. It just slides over the current app about 40% of the screen. Back button as well just an outside touch (which will be passed trough to the app)
  allows to immediatelly go ahead in your workflow.

- Normal click opens an app, longpress opens app detail screen (note: we have only one hidden action on our current recents. If we later decide there could be
  other actions as well...showing a google card menu button on the top right is a very easy task and allready provided from the frameworks_opt_cards lib)
  swipe left or right removes the app from the current tasks

- Pinch to zoom out gesture provides the ability to remove all tasks with a big red warning!!

- All above mentioned actions are animated.

- As usual it is multiDpi compatible

- A lot work went into the optimizing especially for low end non gfx devices where animations
  as well listview scrolling is not that easy. We got the maximum out of optimization here which
  gives acceptable results on low end devices and amazing one on the gfx capable devices.

- A small side note this patch contains as well a fix on navigation bar preload.

Thats the short description.....user need to see it to get the real benefits of this new way.

cheers

Frameworks: slimrecents: call app details screen correctly

So feedback shows that we only have 2 bugs. For the one patch is up. The other
one is fixed here.

two problems

1. Longpress opened the detail screen twice and wrong

2. It shows up in the task list which it should not. Going inline
   with the AOSP implementation of it.

use TaskStackBuilder to call it proper with our animation on top.

Frameworks: slimrecents: allow closing recents in middle of the open animation

As reported by Tejus Kandachar steps to reproduce:

Press Recents button and very quicky tap on one of the apps in the recents list,
just as recents list is sliding in. If done fast, the app opens but recents screen does not close.
If done normally it slides away as expected.

Fix it with allowing to close the pannel as well on animation in state.

Frameworks: Slimrecents: cover bad 3rd party apps behaviour

Recent app screen as well the original AOSP one needs a proper preloading.
We discovered due of reports that a lot apps (launcher etc) just call over
the SystemUIService some even with reflection :/ just the toggle and no
preload at all.

Whatever we cover this behaviour due that we do not want to break 3rd party
apps. If someone calls the toggle without proper preload we preload them first before
the recent starts animating. Listener takes already care on it for low end devices. We
just use this now and let the taskloader in this case decide when the recent app screen
can be shown.

As well this commit disables the logcat spam lol. Forgot to disable debug on the relase
commit

PS:
- fixed code style issue
- go on out animation down in the runable delay. Not needed to be that long at all

PS:
- add another safety check

PS
- another one

Frameworks: SlimRecents: go more inline with AOSP and add menu + new googly shortcuts

This commit changes the longpress behaviour. Like on stock aosp longpress opens the menu with this options

1. App info (like stock)

2. Play Store link to the app

3. Amazon store link to the app

Note: the store links are only shown if the app has the info that it was installed by one of this
stores. So stock apps (installed by system) or sideloaded apps do not show this link.

As well some backup apps break this entry on restore lol.

As well a bit cleanup on here and there and remove the close panel call on cancelPreload. Not needed

PS
- disable debug

PS
- set correct style
- disable one default debug

Frameworks: fix the random fc on pinch

Well logic error from me which can lead in an recycle bitmap fc due of a race
condition. Reason is simple it the animation needs for whatever reason longer then
the removing the tasks the view is probably still visible and recycle of the bitmap
results in a fc.

To fix it just remove the tasks after the animation is done and we definitly know
that no items are visble which are recycled.

Frameworks: go kitkat + style tweaks and follow googles color sheme

Googles color sheme on cards is

card: ffffff
aditional content: f5f5f5
background: e5e5e5

first two we did...background not. Follow the color sheme due it has a better contrast.

As well remove the non google rounded edges.

Allow drawing behin status and navigation bar if the bars are translucent

PS:
- due it is now a system window ensure that all other system windows are closed when opening recents.
PS
- minor tweaks
PS
- remove one unused flag
PS
- respect app system ui visibility status and reflect it for smoother experience
PS
- bring back TYPE_RECENT_OVERLAY window layouparams back to live. It was never documented
nor depreciated. Was used in the past for GB recents and is even updated till today although
nothing in the system is using it.

Make it fully functionall (it is basically just an extended TYPE_SYSTEM_DIALOG) and allow
this window type to extend its content behind navigation bar.

PS
- minor fix...init the systemUI flags for the view allready on preload to prevent positioning
of the listview.
PS
- draw always behind navigation bar as long it is not immersive mode or hide navigation bar mode
- add more margin to the delete icon for kill all

well it does not effect us due that we proper preload etc. But if it is not

Frameworks: SlimRecents make it RTL/LTR aware + scaling + lefty mode (1/3)

This commit adds several features:

- Make it fully RTL/LTR aware. Means it shows up on the oposite side if an RTL
  language was choosen. As well icon, textposition, menu etc follows RTL direction.
  So like AOSP guidelines suggest it is fully compatible now for all locals

- Add scaling mode....user can scale the overall size down (especially for the
  user with stock dpi requested)

- Add lefty mode. Recent panel shows up on the left edge instead of the right edge

As well this commit unlinks the construct of the card with the update of the content. This
reduces one update call on construct and gives a tight faster loading.

Frameworks: add favorite mode

Allow user to set favorite apps in recent task list. User can set them with
longpress on the app icon. This apps are always shown in the task list above
the first default one (on phone the first 2 which always show the last 2 active
tasks). Favorites are shown in order of last time they were called. Favorites
settings are saved permanently till the user removed it from favorites.

As well this commit fixes the wrong icon if an package has more then one
activity to call (eg Google+ and Google Photo).

Using for all now a unique identifier.

Frameworks: notify arrayadapter early that data has changed on clear all

Recent clear all. Current behaviour is that we do not update the array adapter at all
due that it gets rebuild on next reload. But in very rare cases it happens that getView
want to update shortly after all is cleared althought the view is not visible anymore.

Whatever just call notifyDataSetChanged after List is cleared to work against it.

Frameworks: do not kill favorite recent apps

Due of a lot user requests and I basically like the idea (not a fan of clear all apps at all
due that it does not make sense android wise) we ehance the favorite recent apps feature.

This commit basically does not remove the apps from the task list which were marked from the user
as favorite.

3 possibilities:

- No favorites are in the task list - clear all behaves like it was before - all tasks cleared and panel closes

- favorites and non favorites are in the task list - clear all removes all non favorite tasks and favorite tasks stay.
  Yes without fancy animations....we want to be fast ;) - panel stays open

- only favorites are in the list - pinch to zoom out is blocked due that nothing is there to clear all.

single clear of a task with swipe behaves in all cases normal like it was before this change

SlimRecents: Adress the 50ms touch unsresponsive issue

User reported that if the screen is fully animated in that the touch
detection is not working for about the first 50ms. For user who are working
fast this is indeed an issue. Especially due that the recent screen speeds
up the workflow much already.

Problem is our third loading stage due that after the recent screen animates in
it calls getView on all elements which rebuilds the touch listeners and cause to
the slight timeframe where it is unresponsive.

Well the third loading stage was a left over from the first optimizations when
we started to develop this feature. Other optimizations are into place now so we
do not really need the third loading stage at all. So instead of handling now
the fix in the getView implementation of the arrayadapter we simply just remove the
third loading stage completely.

PS:
- small other optimization

Frameworks: SlimRecents: user configurable default expanded mode (1/2)

A lot requests to customize the default behaviour

auto = like it is now....dependend on the overlay the first tasks are expanded other collapsed

never = always all collapsed

Of course still user changes directly in the recent panel counts more then the default settings
behaviour

PS
- correct code comment to new behaviour
PS
- fix typo
