// Allows to call a Android java function asynchronously
// spawn long running computations/io on the Java/Android without blocking the JS/Website running inside the WebView
// Eg. const result = await callAndroidAsync('javaFunction', { param1: 'value1', param2: 'value2' })
// Please give a star if you find this useful

export async function callAndroidAsync(javaFuncName, params) {
	const rand = 'asyncJava_' + Math.floor(Math.random() * 1000000)
	window[rand] = {}
	
	// func called from android

This script attaches a stopwatch into the toolbar of Leetcode's problem page.

The feature is simple:

• Start/Stop the stopwatch
• Auto start after 2 mins remaining on the problem
• Restore unstopped stopwatch for the next visit on the problem

Use this script with any browser extension allowing attaching JS to the page. (I use User JavaScript and CSS)
