Actions

Actions are the fundamental building blocks of Tasker tasks. An action represents a single operation that Tasker performs, such as displaying a notification, changing a system setting, launching an application, manipulating variables, or executing code.

Tasks are composed of one or more actions that execute in sequence. Nearly every automation in Tasker ultimately consists of a series of actions.

Overview

Actions define what Tasker does when a task runs. Each action belongs to a category and may contain parameters that determine its behavior.

For example:

• Turning Wi-Fi on

• Setting a variable

• Sending an SMS

• Showing a notification

• Performing a web request

• Executing JavaScript

• Running Java code

A task may contain a single action or hundreds of actions depending on the complexity of the automation.

Structure

Each action consists of:

Action Type

The operation that Tasker will perform.

Parameters

Settings and values used by the action.

Conditions

Optional requirements that determine whether the action should execute.

Labels

Optional names used to identify actions for navigation and flow control.

Execution

Actions normally execute from top to bottom within a task.

Example:

1. Variable Set

2. Flash

3. Notify

In this example, Tasker performs each action in sequence.

Execution order can be modified through flow-control actions such as:

• If

• Else

• End If

• For

• While

• Goto

• Stop

Action Categories

Tasker organizes actions into categories.

Alert

Actions that interact directly with the user.

Examples:

• Flash

• Notify

• Popup

• Vibrate

• Beep

App

Actions that interact with applications.

Examples:

• Launch App

• Kill App

• Browse URL

Code

Actions used for scripting and logic.

Examples:

• Variable Set

• Variable Search Replace

• Java Function

• Java Code

• JavaScriptlet

• Run Shell

Display

Actions that control screen behavior.

Examples:

• Display Brightness

• Display Timeout

• Auto Rotate

File

Actions used for file management.

Examples:

• Read File

• Write File

• Delete File

• List Files

Image

Actions that manipulate images.

Examples:

• Load Image

• Resize Image

• Rotate Image

• Save Image

Media

Actions related to audio and media playback.

Examples:

• Music Play

• Media Control

• Say

• Play Ringtone

Net

Network-related actions.

Examples:

• HTTP Request

• Wi-Fi

• Bluetooth

• Mobile Data

Plugin

Actions provided by external plugins.

Examples:

• AutoTools

• AutoNotification

• AutoVoice

• Join

Scene

Actions that manipulate Tasker scenes.

Examples:

• Show Scene

• Hide Scene

• Element Text

• Element Visibility

Task

Actions used to control task execution.

Examples:

• Perform Task

• Stop

• Wait

• Wait Until

Variables

Actions used to create and manipulate variables.

Examples:

• Variable Set

• Variable Add

• Variable Clear

• Variable Convert

Conditions

Most actions support conditional execution.

Example:

Flash "Wi-Fi Enabled"

If %WIFI ~ on

The action executes only when the condition evaluates as true.

Error Handling

Many actions support error reporting through Tasker variables.

Common variables include:

• %err

• %errmsg

These variables can be used to determine whether an action succeeded or failed.

Action Icons

Each action category has a unique icon and color within the Tasker interface. These visual identifiers help users quickly locate actions while building tasks.

Advanced Actions

Some actions provide direct access to Android APIs and scripting environments.

Examples include:

Java Function

Allows direct invocation of Android Java methods.

Java Code

Executes BeanShell-based Java scripts.

JavaScriptlet

Executes JavaScript code within a task.

Run Shell

Executes Linux shell commands.

Importance

Actions are the core components of Tasker automation. Every task, project, profile, scene interaction, and generated automation ultimately relies on actions to perform work.

Understanding actions and their categories is considered a foundational skill for Tasker users.
