Global Module

Overview

The global module can be used by calling methods directly, without a prefix object name.

CLI

getCliArgs Get CLI command-line arguments

  • Get CLI command-line arguments
  • When using with AI, prefer CLI args first; fall back elsewhere if unavailable
  • Enables AI auto-parameter passing and post-pack testing from other sources
  • Requires EC HarmonyOS Next 2.16.0+
  • @return {null|JSON} JSON object; null means not launched from CLI
function main() {
    let a = getCliArgs();
    if (a == null){
        // Get from elsewhere
    }
    logd(JSON.stringify(a))
}


main();

Control Center Version

version Get control center version

  • Get control center version
  • @return string, e.g. 2.9.0
function main() {
    logd(version())
}


main();

    // Enter filename only; loads from project plugin directory
    loadDex("ocr.apk");
    // Enter absolute path; loads from PC path
    loadDex("D:/a.jar");
    // Class com.A in the apk can be used directly
    var obj = new com.A();
}


main();

require Import JS

  • Import JS module
  • @param path Path, e.g. local D:/a.js or EC project path slib/a.js
  • @return module object
function main() {
    // Note: do not put JS files in js/ or subdirectories
    test = require("slib/a.js")
    logd(test.c());
}


main();
