Macro Handler

Android Automation Platform

Object MethodSystem Control

Runtime.get(key)

Reads a runtime value by name (such as "scale", "width" or "resolution").

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

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

When To Use It

In system flow, design steps as observe first and act second when the API can affect device state.

Parameters and Return

Required: key. Returns a Lua value of whatever type was stored or read.

Best Combined With

Using this API with logging, error handling, and next-step control produces much more professional results than calling it in isolation.

Example Usage

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

lua
Try in Editor →
local result = Runtime.get("scale")

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 = Runtime.get("scale")

Simple

Wraps the base call with minimal flow control.

Simple
lua
Try in Editor →
local stepOk = true
local result = Runtime.get("scale")
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 = Runtime.get("scale")
end)

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

Detailed

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

Detailed
lua
Try in Editor →
-- In system flow, design steps as observe first and act second when the API can affect device state.
local function run_get_step()
  local result = Runtime.get("scale")
end

local ok, err = pcall(run_get_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 = Runtime.get("scale")
wait(200)
print("Combined with logging and flow control")
