“Show notification” causes a consistent ≈ 1 s delay every ⪆ 8 s.

Prerequisites

• I am running the latest app version.

• I checked to make sure that issue has not already been filled.

What The Problem Is

“Show notification” being enabled causes the GUI to freeze every ≈ 3 – 4 s for ≈ 2 s. Disabling it remediates the problem:

screen-20251101-153755.2.mp4

None of the relevant options depicted as enabled make any difference whether enabled or disabled.

How To Reproduce

Steps to reproduce the behavior:

1. Install apt.izzysoft.de/fdroid/repo/com.truemlgpro.wifiinfo_1610.apk.

2. Leave “Show notification” enabled (by default).

Expected behavior

Whatever's erroneously running on the same thread as the GUI shouldn't be.

My Environment

1. The Application

   sourcePackage=com.truemlgpro.wifiinfo
   versionCode=1610

2. The OS

   [ro.build.version.release]: [13]
   [ro.build.display.id]: [FP5.TT4D.A.157.20240417]

3. The Device

   [ro.product.brand]: [Fairphone]
   [ro.build.product]: [FP5]

[TrueMLGPro]

Not sure about this one, but it should be fixed by 2.0

@TrueMLGPro, it, unfortunately, continues to reproduce in 2.0:

I've not the permissions to, I believe.

My Environment

1. The Application

   sourcePackage=com.truemlgpro.wifiinfo
   versionName=2.0
   versionCode=20000

2. The OS

   [ro.build.version.release]: [15]
   [ro.build.display.id]: [FP5.VT2E.C.059.20250908 ]

3. The Device

   [ro.product.brand]: [Fairphone]
   [ro.build.product]: [FP5]

[TrueMLGPro]

This is a weird one. For some reason I can't reproduce it on any physical device I have

[beedell-roke]

@TrueMLGPro, all of a sudden, I can't, either:

Still versionCode=20000, alongside the same AOSP build.

@TrueMLGPro, although it wasn't present earlier, now that my smartphone is running more slowly, it is. Does AOSP provide something equivalent to perf, so that I can record a performance profile? I see com.android.traceur:

#!/system/bin/sh
cmd activity start --user 0 -a android.intent.action.VIEW -n com.android.traceur/com.android.traceur.MainActivity -f 0 com.android.traceur

Details

URI	intent:#Intent;package=com.android.traceur;component=com.android.traceur/.MainActivity;end

VERSION	1
ACTION	android.intent.action.VIEW
COMPONENT	com.android.traceur/com.android.traceur.MainActivity
PACKAGE	com.android.traceur

MATCHING ACTIVITIES	1
0	LABEL  	System Tracing

 	PACKAGE	com.android.traceur

...which appears to provide similar abilities:

I've at least confirmed, via PCAPDroid, that it's not sending a network request, so it's something local that's causing the thread to hang for a moment:

However, I presume that you know this, being the developer!
