Task automation has become quite a big feature in Android. The success of Tasker and NFC tags brought much in that realm, as modern devices have many sensors that can be used to determine many variables such as location. Some OEMs have even included various predefined automation schemes in their official firmwares.

A few months ago, there was an XDA TV feature about Llama. The program is a free alternate to the popular automation program Tasker. The concept of this application is to create predefined macros that act in various ways in certain scenarios. For example, you can turn WiFi off outside and silence your phone at night.

Another interesting alternative was presented by XDA Forum Member UndeadCretin, who created an application called MacroDroid. With this app, creating a macro is as easy as pie, and takes just few seconds. The list of available templates is impressive, as it has almost 30 predefined presets ready to be used or customized. It's even possible to make your device to speak. This is useful in certain cases, such as when your battery is low.

If automation is your thing, you should give MacroDroid a try. Visit the application thread to get started.
