I would like to illustrate graphically a bandwidth segmentizer. To do so, I would like to represent the following diagram in TikZ

So far, I have the following LaTeX code

TL;DR how can I have an Android sensor permanently running/active/registered for my app, even if I close it?

Objective:
I'm making a Flutter application that counts your steps using the pedometer package,
which uses the built-in sensor TYPE_STEP_COUNTER of Android,
which returns the # of steps taken since last boot (iOS). On Android, any steps taken before installing the app are not counted.

How I implemented it:

• When the app is actively running in the foreground, each step causes a myStepCount to increment by 1.
• In all other cases (phone locked, went to home-screen, closed the app...), the android TYPE_STEP_COUNTER sensor should still be running in the background, and once I open my app again, the difference between new stepCount and last saved stepCount (saved using shared_prefs) will be calculated and added to myStepCount.

Important:
The TYPE_STEP_COUNTER sensor must be permanently running/stay registered in the background, even after I lock my phone, go to the home-screen, or close the app...

Observations:

• On my Samsung Galaxy A02s, my app works perfectly fine, as it it supposed to (as described above). That is because on that phone I also have the Google Fit app installed, which tracks your steps 24/7 (so the TYPE_STEP_COUNTER sensor is permanently registered).
• On my Samsung Galaxy S7, my app does not work as it's supposed to. myStepCount gets incremented when I take steps while the app is running in the foreground. But steps taken while the app is closed will NOT be added to myStepCount once I open the app again.
  Note: I don't have any other step-counting-apps like Google Fit on this phone.

Conclusion:
I need to find a way to register the TYPE_STEP_COUNTER sensor from my Flutter app, and keep it registered even after I close the app.

2 Attempted (but unsuccessful) Solutions:

1st Attempt:
Calling Native Android Code from my Flutter Code to register the sensor
This is my main.dart file (with the unimportant parts left out for simplicity):

I am trying to retrieve step counts from a smartwatch and push it to API. I was able to retrieve and push the data when I open the app. But once it is not activated, then it will not send any data. I am trying to use the android service to run the app in the background so that it will send the data continuously. I have given all the permissions and enabled them.

This is MainActivity.java

This is my first post here and I am not that experienced, so please excuse my ignorance.

I am building a Monte Carlo simulation in C++ for my PhD and I need help in optimizing its computational time and performance. I have a 3d cube repeated in each coordinate as a simulation volume and inside every cube magnetic particles are generated in clusters. Then, in the central cube a loop of protons are created and move and at each step calculate the total magnetic field from all the particles (among other things) that they feel.

At this moment I define everything inside the main function and because I need the position of the particles for my calculations (I calculate the distance between the particles during their placement and also during the proton movement), I store them in dynamic arrays. I haven't used any class or function,yet. This makes my simulations really slow because I have to use eventually millions of particles and thousands of protons. Even with hundreds it needs days. Also I use a lot of for and while loops and reading/writing to .dat files.

I really need your help. I have spent weeks trying to optimize my code and my project is behind schedule. Do you have any suggestion? I need the arrays to store the position of the particles .Do you think classes or functions would be more efficient? Any advice in general is helpful. Sorry if that was too long but I am desperate...

Ok, I edited my original post and I share my full script. I hope this will give you some insight regarding my simulation. Thank you.

Additionally I add the two input files

parametersDiffusion_spher_shel.txt

parametersIONP_spher_shel.txt

I am working on a small checkout stepper with Vue (v 2.x.x).

The current item should have the class name "active" while all the previous ones have the class name "completed", as illustrated bellow:

When app works fine

When app not shows textviews(its finding a sensor. When cant find, giving info on textview like 'didnt found')

I created a pedometer app. It was working well on my emulator and my own android device. But when ı publish that app my friends said textviews are invisible. I examined that problem in code but didnt found a problem. Textviews are getting their text from sensor. Writing steps and calories, after some calculating. Why that problem showed up? What is the source of this problem? Why is this happening?

I'm creating a pedometer app. It is almost done, except for one thing. When day has past, I want to reset step numbers.How to implement sharedpreferences to my code? How can I reset step numbers? I tried this way. But when time past every numbers turning normal value. Not starting from zero.

im trying to develop a pedometer. I got steps with sensor but ı need send them to fragment. For that ı used a bundle. Steps variable is passing to fragment but its only getting first value. That first value is zero and i gave that value when i create variable. This value is updating ım seeing that on stepsTextview. But in bundle not. How can ı get updated variables when sensor changed?

Activity Code:

im trying to make a simple step counter in Android, im currently using Oreo and emulating with Pixel 2 API 29. The problem is that its simply not working, when i call the sensorManager there is no sensor listed neither for STEP_COUNTER or STEP_DETECTOR. I followed different tutorials step by step and didnt work. Does anyone know what could be the problem? Here is my code and manifest, and the list im talking about,
