Macro Handler

Macro Handler

Android Automation Platform

Object MethodLicense and Security

License.getDeviceId()

Returns an identifier tied to this installation of Macro Handler, or an empty string when it is unavailable.

Documented for app version 1.0.51Updated:

Detailed Explanation

This section explains when to use the API, how to call it, and which structures it works best with in production flow.

How To Call It

License is a global table: call its functions with a dot (License.<method>(...)), not a colon.

When To Use It

In security and licensing flow, re-check the result at critical checkpoints instead of trusting a single early validation.

Parameters and Return

Takes no arguments. Returns a string.

Best Combined With

When paired with License and Runtime/System checks, it gives you stronger premium, trial, and security decisions.

Example Usage

The snippet below is a starter pattern that can be applied directly in runtime flow.

lua
Try in Editor →
local result = License.getDeviceId()

Copyable Progressive Examples

From foundation to combined usage, each level is provided as a separate code block so you can copy the level you need and adapt it directly.

Foundation

Shows the shortest direct way to call the API.

Foundation
lua
Try in Editor →
local result = License.getDeviceId()

Simple

Wraps the base call with minimal flow control.

Simple
lua
Try in Editor →
local stepOk = true
local result = License.getDeviceId()
if stepOk then
  wait(200)
end

Practical Flow

A practical pattern for real macros with pcall, logging, and guards.

Practical Flow
lua
Try in Editor →
local ok, err = pcall(function()
  local result = License.getDeviceId()
end)

if not ok then
  print("API step failed: License.getDeviceId: " .. tostring(err))
  requestStop()
end

Detailed

This level packages the API into a reusable helper with error reporting.

Detailed
lua
Try in Editor →
-- In security and licensing flow, re-check the result at critical checkpoints instead of trusting a single early validation.
local function run_getdeviceid_step()
  local result = License.getDeviceId()
end

local ok, err = pcall(run_getdeviceid_step)
if not ok then
  toast("Step failed")
  print(err)
end

Combined

Combines the API with related structures to form a more realistic workflow.

Combined
lua
Try in Editor →
local result = License.getDeviceId()
wait(200)
print("Combined with logging and flow control")
