With Android 5.0, there was a complete revamp of the “Recent Tasks” implementation on Android. The changes impact the way we think of tasks, as well as how they are presented in the Overview Screen. I may get into the logical, and implementation level changes at a later date, but first we tackle the visual changes.

To keep the UI in line with the colorful, fun, approach of the rest of the OS, an API was introduced to give developers some manner of control over the presentation of their tasks in the Overview Screen. The entry has three components: Label, Icon & Color.

Styling Recent Tasks

Following is a small code-snippet that takes care of the styling for you :)


/**
 * Helper class that applies the proper icon, title and background color to recent tasks list.
 */
public class RecentTasksStyler {

    private static Bitmap sIcon = null;

    private RecentTasksStyler() {
    }

    @TargetApi(Build.VERSION_CODES.LOLLIPOP)
    public static void styleRecentTasksEntry(Activity activity) {
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
            return;
        }

        Resources resources = activity.getResources();
        String label = resources.getString(activity.getApplicationInfo().labelRes);
        int colorPrimary = resources.getColor(R.color.theme_primary);

        if (sIcon == null) {
            // Cache to avoid decoding the same bitmap on every Activity change
            sIcon = BitmapFactory.decodeResource(resources, R.drawable.ic_launcher);
        }

        activity.setTaskDescription(new ActivityManager.TaskDescription(label, sIcon, colorPrimary));
    }
}

Just call this in the onCreate of any activity, and it will apply the default app theme to the Recent Tasks entry.

It's kinda sad that the folks at Facebook cannot find time to add 10 lines of code.

I’ve been using ParanoidAndroid 1.92, a Jelly Bean ROM, as a daily driver on my I9100 for the past week, thanks to CM10 team, and D4rKn3sSyS over at XDA. There have been *almost* no issues so far. I’ve had some people asking how JB is different from ICS, and so I thought it’s time I post about my experience so far.

Given that it is still an experimental build, there might be more improvements in the pipeline, and if that happens, I’ll take the time out to post a second review (or update this one). So anyway, let’s move on to the first impressions.

The performance has been amazing even without the Project Butter implementation! It feels a lot faster than ICS. It has some flashy screen transitions, but on the whole, keeps the ICS look and feel which, in my books, is a win.

Google Now is a whole new ball-game. Now does not even require you to ask for things… All relevant information is all displayed as a stack of cards. In fact, Now is smart enough to know that I don’t need to know about the traffic on my way to work on the weekends.

Google Search now uses Google’s Knowledge Graph implementation. Add Voice Search to that, and we have a winner. With the instantaneous responses, it leaves even Siri biting the dust. Voice Search has a better, faster way of presenting information compared to Siri, though it does lack the functionality to add and edit calendar events and such (one of the new things coming in iOS6’s Siri.)

The revamped Notification Tray is out-of-this-world! We all know it provides the ability to display larger notifications, but there is no way you can imagine the impact of this small enhancement till you see it in action. Entire texts and emails can be read, screenshots and images can be previewed, calls made and ended, directly from the notification.

Offline Dictation is simply brilliant! You could easily type out entire emails using it, but to be on the safe side, it does require proofreading.

The Homescreen has been one of the key features of Android’s UI, and it’s great to see that even such a tried and tested system has got some major usability upgrades. Icons simply move out of the way (if possible), instead of giving the “not enough space” toast, making is infinitely faster to rearrange or customize the layout.

The Camera has seen some interface change as well. Now we can simply swipe left to get into the gallery. Pinch to zoom out of the picture on the screen, and you get into a quasi-film-strip view. Swipe all the way to the right, and you get back to the camera. The camera also shows focus state, so you know what’s going on while shooting photographs.

Things are not rosy all-around though. In my first two days with JB, I charged my phone 4 times—that’s a 12 hour life on an average—and I used to get at least twice that with ICS. After letting the ROM “settle” I have noticed better standby times, but as soon as the screen is on, the charge nosedives; in short, battery life disappoints. Given the functionality and performance, and keeping in mind that it’s only an experimental preview, I must say battery shouldn’t be your top priority. What are extended cells for, anyway! 😀

On the whole, JB is just an incremental update, but I’m quite hopeful about how things are turning out. Maybe with the next Android release (the rumoured Key-Lime Pie), Google will have an answer to Passbook.

PS: It seems that PA1.95 is out! It’s going to be another long night…

I’ve been testing Jelly Bean ROMs over the past few days. I’ve tried three—CM10 Preview, CM10 X-TremE, and ParanoidAndroid 1.92.

They all work flawlessly as stock, except for one thing: gaming performance sucks. So I looked in the forums for a fix, and stumbled upon Dream Kernel. And performance has been dream-like ever since. I believe Dorimanx kernel has been updated to support JB as well!

I’ve been using ParanoidAndroid as a daily driver on my I9100 for the past couple of days, and thanks to CM10 team, and D4rKn3sSyS over at XDA, and I must say, there have been *almost* no issues so far.

I do not think there could be a more stable and functional “Preview” build out there. The only bits not functional yet are HW Composer and Audio over Bluetooth, and there will be updates to get them working quite soon. PieRs Kang even has HW Composer implemented, and that means it has Project Butter working.

There are rumours that Siyah will be updated to support Jelly Bean. I noticed that non-availability of Siyah was a deal breaker for many, but even that is about to change!

Here are the links to some of the ROMs I’ve been talking about…
