Long startup delay in certain scenario

[MatthewScholefield]

Problem Description

Sometimes when I would click a script widget I noticed the script would run a second time there would be a 1-3 second startup delay. Then experimented and narrowed it down to a specific situation.

Steps to reproduce

• Use Oneplus Launcher
• Close a recent app other than Termux
• Immediately launch a Termux widget icon

Expected behavior
Script runs immediately.

Actual behavior
Delay of 1-5 seconds before launch.

Video: video link

• Termux application version: 0.108
• Android OS version: 11
• Device model: Oneplus 8T

A close look at your *.mp4 shows double tap. So I expect twice

Oh, haha, it's so subconscious I didn't even realize it. I guess it's just that oneplus launcher momentarily prevents the launching of apps after clearing another app from memory for some reason.

[MatthewScholefield]

Actually, I realize the lag is exceptionally long, sometimes up to three seconds or so, but only for termux widget (all other ~20 apps I tried including Termux are still instant). To give more info to oneplus developers, I wonder, is there anything unique about how it launches? My only thought is that it sends a toast notification each launch and it might be related to that.

Edit: Reopened because of this followup

I can not repeat that on any of my devices and not in my Android 11 emulators.
You deleted the source of your example! There where actions (.bashrc) that can contain a delay. The loop probably does not make it.
I have used another example that also echo$RANDOM, edited it withnanoand can be delayed terminatedexit 1(remove#)

a='#!';s=.shortcuts;mkdir $s;c=$s/check; echo "nano $c">$s/nano
printf '%s\n' "$a$PREFIX/bin/bash" 'echo rand:$RANDOM' '#exit 1'>$c

I don't know, why this*.mp4 video in github is not viewed, (your above works) but have it again as Dropbox
