Hello, I am currently working on a simple android app for a smart irrigation system. Basically the app lets the user enter the name of the plant and then lists all the plants of the garden. Then, I have divided plants into three categories depending on their watering needs and I have created three int values for the amount of plants per group. Essentially I want to send these three values to a thingspeak channel I created, to 3 separated fields. I am not familiar at all with server programming in Java so I would really appreciate any kind of help in how to do this. Send three integer values from android studio to three fields in a thingspeak channel Here's a <https://github.com/angryelectron/thingspeak-java related repo> . android java thingspeak

I would like to be able to issue this: https://api.thingspeak.com/update?api_key=myapikey&field1=634567 from an android app. Do libraries exist that I could import into a android java project to make it easy? Or what would be the raw java code to do this?

I wish to send an image taken from Android device to a server which will do all the MATLAB pre processing and return the result back to the Android device.

Hello, I'm trying to create an android app to subcribe and publish ROS messages. As soon as I insert ROS elements in Simulink model my "Deploy to Hardware" fails. In the diacnostic i get: Error(s) encountered while building "Test": ### Failed to generate all binary outputs. This is the Simulinkmodel which I want to deploy to my smartphone. <</matlabcentral/answers/uploaded_files/92252/Test_Model.PNG>> This is my solver options ( I tried different solvers) <</matlabcentral/answers/uploaded_files/92253/Solver.PNG>> This is my Hardware <</matlabcentral/answers/uploaded_files/92254/Hardware.PNG>> This is my Code Generation <</matlabcentral/answers/uploaded_files/92255/Code_Generation.PNG>> And this is my Diacnostic I get <</matlabcentral/answers/uploaded_files/92256/Diacnostics.PNG>> It's like only the ROS elements caused this failure, if I create a android app with a model without ROS elements the deployment works fine.
