Train your Android phone to act automatically with Tasker

(Credit: Screenshot by Sharon Vaknin/CNET)

Get started with Tasker, an Android app that lets you automate settings, apps, and more.


Every day, we repeat the same routine tasks: turning on Wi-Fi at work, decreasing the brightness in the evening, enabling silent mode at night, and so on.
By now, you probably perform these actions subconsciously, but what if you could "train" your phone to automatically complete these tasks, so you don't have to?
Tasker [Google Play link], a $6.49 app for Android, lets you do just that. It works like this: If the phone is in X situation, then Y happens. Within the app, this formula is defined by using "contexts" and "tasks."

• The context defines the situation in which the task is triggered. For example, time of day, location, or the state in which your phone is in (like charging).
• Tasks are the actions the phone takes when it's in any given context, or situation. This can be anything from toggling a system setting to sending a text message.

For example, when my phone is at 20% battery life (context) disable Wi-Fi (task).
There are endless combinations of contexts and tasks that can be as simple or as complicated as you want. Android user forums are filled with the many creative ways users are taking advantage of Tasker, but if you're a newbie, you'll probably want some basic guidance first.


When you launch Tasker, you'll arrive at the Profiles tab. This is where the formulas you created (contexts and tasks) are listed. At the bottom of the screen is a large green + sign, the button you'll use to create new profiles.
The best way to master Tasker is to get your hands dirty. So, try programming one (or more) of these useful tasks to get a taste of how this powerful app works.
1. Launch music apps when headphones are plugged in
With this Task programmed, every time you plug in your headphones, a menu of your music apps will appear.
Tap the + sign to create a new profile. Name it something like "Music" and tap the checkmark. In the Context menu, select State > Hardware > Headset Plugged. In the next screen, just tap the green checkmark.
Next, the Task Selection menu will appear. Select "New Task" and name it something like "Launch music." In the next window, tap the blue plus sign. Basically, everything your phone can do is listed here. For this example, select Alert > Menu.
In the "Items" section, tap the grayed-out "Action" button. Then select App > Load app, and select one of the Music apps you'd like to load. To add another app to the menu, select the green + sign, tap "Action," and repeat the same process.
When you're done, tap the green checkmark.
2. Disable features when battery is critically low
This task will disable energy-hogging features when your battery is critically low.
Tap the + sign to create a new profile. Name it "Battery" and tap the checkmark. In the Context menu, select State > Power > Battery Level. Keep the "From" slide at 0, and change the "To" slide to 20 (or your preferred battery level.) Tap the checkmark.
In the Task Selection menu, tap "New Task" and name it something like "Low Battery." In the next window, tap the blue plus sign. Here's where you'll select the settings that are disabled when your battery is critically low. To disable Auto-Sync (push data), go to Net > Auto-Sync, and tap the checkmark.
Tap the blue + sign again to add another task, like disabling Wi-Fi. Again, go to Net > Wi-Fi, and tap the checkmark.
Repeat this process for any other settings you'd like to disable. Bluetooth can also be found in the Net menu, and brightness can be found in the Display menu.
3. Trigger a task with an app-like icon on your home screen
Tasks are usually associated with triggers, like location, time, state, etc. However, you can assign a task to an icon-like widget that appears on the home screen, so that the task is only triggered when you tap it.
To create a widget, or shortcut, long press a home screen, and tap "Add to Home Screen." Then, tap Apps, and go to the Widgets tab. This process may vary depending on the version of Android you're running and your OEM's skin.
Find the Tasker widget and add it to a home screen. Immediately, a "Task Selection" menu will appear. This is where you'll decide which tasks are triggered upon tapping the widget icon. Tap "New Task," give it a name, and tap the blue + sign to add your first task.
What you select here will vary, but there are over 100 options, from composing a text message to a specific person, to disabling Wi-Fi and opening settings menus. You can add any number of tasks to this widget -- just tap the blue + to add more tasks.

As you can see, Tasker is a seriously poweful app, and with a little practice, you can use it to make your life a whole lot easier. The crazy thing is that these few examples hardly scratch the surface of what Tasker can do. Once you get comfortable with the interface and have programmed some tasks, there are a few ways you can advance your Tasker mastery:

• Check out the forums where users are exchanging ideas for tasks
• Get seven more awesome tasks from CNET UK's guide to Tasker
• Learn how to use motion gestures to trigger tasks
• Combine NFC Task Launcher with Tasker to trigger tasks whenever an NFC tag is scanned (tutorial incoming)

And, by all means, if you have any cool ideas for Tasker, please share them in the comments. We'd love to include them in a future roundup of Tasker profiles.

NASA Asteroid Analog Mission Tackles Surface Mobility

HOUSTON — NASA’s undersea analog missions — elaborate dress rehearsals that unite astronauts, scientists and engineers on the ocean floor to test hardware and mission operations strategies — are playing a crucial role in preparations for the next wave of human deep-space exploration, according to Steve Squyres of Cornell University, principal investigator for the Mars Exploration Rover mission and the current chair of the NASA Advisory Council.
Squyres is scheduled to surface June 22 from his second visit to the Aquarius Reef Base off Key Largo, Fla., an undersea habitat chosen by NASA’s Extreme Environment Mission Operations (Neemo) to simulate a 12-day mission to a small asteroid.
“I feel what we are doing is extremely valuable,” Squyres said in a June 21 interview. “The problem we face is how do you do field work in microgravity. Asteroids are effectively a zero-g environment. No one knows how to do that. Hit a rock with a hammer and you will go flying. So we need completely new techniques for getting around and stabilizing yourself at a worksite.”

This Is China's Response To The US Navy's Struggling Coastal Warship Program

The fact that China's been building up its military with speed and agility recently is nothing new, but Beijing is now going head-to-head with one of the U.S. Navy's most troubled programs.
The Navy's Littoral Combat Ship (LCS) is meant to be part of the fleet being moved to the Pacific, and though a couple versions of the ship were put to sea four years ago, the program is still beset by problems and nowhere near combat ready.
Michael Fabey at Aviation Week acquired Navy documents that show the following components had issues on the LCS USS Freedom's recent voyage:

In the Facebook Era, Reminders of Loss After Families Fracture

Not long ago, estrangements between family members, for all the anguish they can cause, could mean a fairly clean break. People would cut off contact, never to be heard from again unless they reconciled.

 But in a social network world, estrangement is being redefined, with new complications. Relatives can get vivid glimpses of one another’s lives through Facebook updates, Twitter feeds and Instagram pictures of a grandchild or a wedding rehearsal dinner. And those glimpses are often painful reminders of what they have lost.

“I frequently hear, ‘I heard from somebody else who read it on Facebook that my son just got married,’ or, ‘My daughter just had a child, and I didn’t even know she was pregnant,’ ” said Joshua Coleman, a psychologist in the Bay Area who wrote a book about estrangement, “When Parents Hurt.” 

Incentives for Drivers Who Avoid Traffic Jams

London, Singapore, Stockholm and a few other cities around the world battle heavy traffic with a “congestion charge,” a stiff fee for driving in crowded areas at peak hours. But drivers generally hate the idea, and efforts to impose it in this country have failed.

SENSOR Chinmoy Mandayam,

 a graduate student at Stanford, 

adjusted a solar-powered traffic scanner.

Balaji Prabhakar, a professor of computer science at Stanford University, thinks he has a better way.

A few years ago, trapped in an unending traffic jam in Bangalore, India, he reflected that there was more than one way to get drivers to change their behavior. Congestion charges are sticks; why not try a carrot?

So this spring, with a $3 million research grant from the federal Department of Transportation, Stanford deployed a new system designed by Dr. Prabhakar’s group. Called Capri, for Congestion and Parking Relief Incentives, it allows people driving to the notoriously traffic-clogged campus to enter a daily lottery, with a chance to win up to an extra $50 in their paycheck, just by shifting their commute to off-peak times.

The program has proved so popular that it is to be expanded soon to also cover parking.

Amaya Odiaga, the director of business operations for Stanford’s physical education department, now drives to campus a few minutes earlier and says she has won just $15. But a co-worker got $50 — creating a competitive atmosphere that makes the program fun, Ms. Odiaga said.

Better yet, Ms. Odiaga’s commute now takes as little as 7 minutes, down from 25 minutes at peak hours.

Dr. Prabhakar is a specialist in designing computer networks and has conducted a variety of experiments in using incentives to get people to change their behavior in driving, taking public transit, parking and even adopting a more active lifestyle. Unlike congestion pricing, which is mandatory for everyone and usually requires legislation, “incentives can be started incrementally and are voluntary,” he said.

Facebook Begins Ad Bidding System

In its quest to bolster the growth of its digital advertising, Facebook is slowly breaking down its walled garden for advertisers.

On Wednesday, the company announced it would begin testing a new advertising mechanism using a technology called real-time bidding, which allows advertisers to place bids on ad space at specific times.
For the new system, called Facebook Exchange, the company is working with a number of ad networks that will be able to use cookies in Web browsers to track users after they visit Facebook and show them ads based on their Web browsing habits – a process known as retargeting.
So a Facebook user who visits a travel Web site to buy airline tickets but does not complete the purchase may see an ad on Facebook that will allow them to do just that. Facebook is only displaying the traditional thumbnail ads that users see in the right hand column of the page and not other ads like sponsored stories or mobile ads.

Google Wants Love and 100 Other Things

Google wants love. But so do six other companies. They are after .love, actually, a new “top-level domain” that could catch on as .com, .org and .net did.

Love might not prevail, but chances are, at least one of the domains in 1,930 applications for new extensions will. The domains are the letters that follow the dot in Internet addresses, and the Internet Corporation for Assigned Names and Numbers, known as Icann, revealed the new requests on Wednesday.
