...the App can check if the Ardunio has a signal first. Any how, the App itself has the same potential issue when sending data.
Correct but the idea is that this is gonna be a wearable , that means we take with us wherever we go .
So in case you wanna go somehwere close or for a walk i know LoRA will fix my issue , but i want this project to be completely remote .
For example i wanna take this wearable and go to the mountains , and send data to TS server via APP if phone has Mb( no buying a sim card on arduino will be faaaar too costly).
Its kinda Weird what i want to achieve with this , i just came up with this idea and it was too interesting
Not sure you will have a good enough signal in the mountains 
Anyway - discovered the issue when the test sent only 1 value - ThingSpeak doesn't like it! Requires a stream. The free version however is very slow, they promise fast performance with the business version.
Knowing all that, I have a working example using Web GET. No json required (remove from Channel setting if you have that).
Edit this project to insert your Write Key, then run via the companion on your phone.

Hello Chris ,Good Morning .
Your example works And it actually sends normal values to my channel.
I implemented it to my code and it connects but again :
While it shows its uploading the value , it reads it as 0.
All i can think off is that the value is not an integer the moment the app receives it , because in your example, the value is an integer the moment it leaves the app and joins Thingspeak.
So i know that the value gets into a String in order to be sent but the app doesnt recognize it as an integer in the first place .
Its like we remove " " from the string value we receive from arduino and then we pass it again to a String .
Changed API key no worries
I tried this :
but now it doesnt even connect.
The idea is that we need something like this
String [] str = {"123", "345", "437", "894"};
int size = str.length;
int [] arr = new int [size];
for(int i=0; i<size; i++) {
arr[i] = Integer.parseInt(str[i]);
No, it's part of the URL string and therefore it's a string representing an integer, a string without any decoration (no speech marks or brackets).
its set to 0 and receives an integer ,
Then this integer becomes part of the URL and it becomes a String , but before is being sent its an actual int right?
That is true, but should make no difference.
If you want to, you can "intify" your cleaned-up string by adding a math zero to it.
I suggest you set the Label_Msg as I have, this shows exactly the assembled URL.
...and since you have doubts in your mind, here is an example where the values are strings and have never been integers:

Amazing , then the App inventor should be correct as it is right now .
So maybe my Code is Wrong or i have no idea whats going on really.
Nor do I 
Did you try:
Also, is there something odd on the ThingSpeak side? I'm just using a tiny fraction of it as I know next to nothing about it.
Since it was uploading your example ,i really have no idea whats going on .
Maybe i should try another platform , or start coding my App in Java
.......Well, I think that might be like jumping out of the frying pan and into the fire. 
My only problem and the biggest one , is that i ve never made an app that connects to BLE so yea 
But really thanks alot for your time that u devoted , i really appreciate it .
I think it's a case of "the devil is in the detail" - on the app side, the syntax has to be 100% correct. On the ThingSpeak side, it might be worth starting again with a new account.

Will do that and check for sure , i ll come back if i manage to make it , with or without android studio
I just noticed that the commercial licence is high cost, £550 per year. It would cost you only a fraction of that to host your own website.
I know its expensive , but a friend of mine has enterprise license in Thingsboard i can use , i just wanted to make sure it uploads to an IoT platform first.
If Thingsboard has different method i am gonna kill myself.
Or i can use the MQTT extension and use this standard communication protocol with a broker server .
