Shake Light - Tasker

First off, what is Tasker?

Tasker is an Android app that allows you to fully customize aspects of the OS experience. Extensions have been built using the Tasker API to automate many aspects of phone & media management. The developer is super responsive to feedback and early on most new ASOP APIs available. When you have a profile active (conditions are met), then tasks are “run” to perform desired updates.

Check out Android Central’s What is Tasker for a full breakdown.

This is a great starter profile. Difficulty to implement is easy.

Shake Profile

The shake profile condition has been added by default so adding it is as simple as creating a new Profile and then finding Shake under the Sensor category.

Sensor Category Profile Options

There are a few options you can set for the shake condition: direction, sensitivity, and duration. For this profile, I used Left-Right direction with medium sensitivity and medium duration. You’ll want to tweak it if you experience a decent amount of false triggers or when you attempt a shake and it doesn’t register. I get a decent amount of false triggers when I ride my bike but it’s pretty good otherwise.

Once you’ve set the Profile you can add a task to toggle the flashlight.

Toggle Flashlight Task

Head over to the newly created task, give it a name, and select Torch in the Alert category. I’ve also elected to add a short 100ms vibrate to this task also so that I’m aware when the light might accidentally trigger and can shut it off and not waste too much battery.

I’ve noticed depending on your battery settings, this won’t work with the screen completely off. Turning the lockscreen on is usually enough to wake the sensor. If the fingerprint sensor is within reach I’ll flip the lock onto the homescreen prior to shaking.

Let me know if it works for you! Got a suggestion, hit me up.
