Do you wish to upload data to ThingSpeak from your Android phone, or from MATLAB running in your computer?

To send data to ThingSpeak from desktop MATLAB, you need to have the ThingSpeak Support Toolbox installed ( https://www.mathworks.com/matlabcentral/fileexchange/52244-thingspeak-support-toolbox ).
Once you have the toolbox, you use the "thingSpeakWrite" function directly in MATLAB.
thingSpeakWrite(17504,[2.3,1.2,3.2,0.1],'WriteKey','23ZLGOCCU9VWHG2H')
This code sends data (2.3,1.2,3.2,0.1) to a ThingSpeak channel (17504). In your case, you would have your own channel and your own WriteKey. If you have a MathWorks account, you can sign into ThingSpeak without signing up.

Tried this and worked on matlab but once I package the app made with >>guide, it doesn't work when I install elsewhere. The app is supposed to take in data from thingspeak and plot on the app. When I run the code it works properly but on app it doesn't.
