ThingSpeak

Hi, I am planning to develop an IOT project in which I control my hardware through an android application. For that, I would have to connect my android application to thing speak server, subscribe and publish data through MQTT api etc. Is there any tutorial following which I could achieve this or is it even possible to create such a connection on Thing speak platform?

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 am attempting to take a user input value on an android application and then upload that value to ThingSpeak for further use. I am trying to use Android Studio and Kotlin, but I keep getting the same error. Any guidance will be much appreciated as I would just like to get the application to run. I have created a Button to execute and Two Texts - Number (Signed) for input. Below is the code that I have attempted: import android.os.Bundle import android.view.View import android.widget.Button import androidx.appcompat.app.AppCompatActivity import com.squareup.okhttp.Request import com.squareup.okhttp.OkHttpClient class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) val waterAmount = findViewById<View>(R.id.WaterAmount) val temperatureAmount = findViewById<View>(R.id.TemperatureAmount) val dispenseButton = findViewById<Button>(R.id.DispenseButton) dispenseButton.setOnClickListener { val okHttpClient = OkHttpClient() val builder: Request.Builder = Request.Builder() val request: Request = builder.url("https://api.thingspeak.com/update?api_key=APIKEY&field1=" + waterAmount).build() } } } The error that I keep receiving is: Duplicate class org.objectweb.asm.AnnotationVisitor found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.AnnotationWriter found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.Attribute found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.ByteVector found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.ClassReader found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.ClassVisitor found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.ClassWriter found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.Edge found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.FieldVisitor found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.FieldWriter found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.Frame found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.Handler found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.Item found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.Label found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.MethodVisitor found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.MethodWriter found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.Opcodes found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.Type found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.signature.SignatureReader found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.signature.SignatureVisitor found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Duplicate class org.objectweb.asm.signature.SignatureWriter found in modules jetified-asm-3.1 (asm:asm:3.1) and jetified-asm-4.0 (org.ow2.asm:asm:4.0) Go to the documentation to learn how to Fix dependency resolution errors.

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?

Dear colleagues, I try to implement this <https://github.com/angryelectron/thingspeak-java ThingSpeak-java> , but after javaaddpath('... Documents\MATLAB\thingspeak-java-master\lib\log4j.jar') import org.apache.log4j.* I do not know what to do next. I cannot use the standard Matlab library for ThingSpeak, because it is not supported by compilator. Thank you for your help Z.
