How can our own custom app read data from the thingSpeak server using the thingSpeak API?
As I have seen from other resources, the code I tried to use to connect my application to the thingSpeak server contained numerous errors, which prevented me from succeeding. I want to use my application to connect to the ThingSpeak server, but I keep getting errors.
The following permissions have been added to the app's manifest file:
'<uses-permission android:name="android.permission.INTERNET"/>
'
[Internet permission code] [1]
Then, incorporate the Volley library into the build.gradle file for the project and sync it: [Volley library code ] 2`
'implementation 'com.android.volley:volley:1.2.1'
added all volleyball libraries to the request: [Imported all the libraries] [3]
import com.android.volley.Request;
import com.android.volley.RequestQueue;
import com.android.volley.Response;
import com.android.volley.VolleyError;
import com.android.volley.toolbox.StringRequest;
import com.android.volley.toolbox.Volley;
After that i have created a new ACTIVITY 5 and write cide there:`package com.example.simp;
import android.os.Bundle;
import android.util.Log;
import androidx.appcompat.app.AppCompatActivity;
import com.android.volley.Request;
import com.android.volley.RequestQueue;
import com.android.volley.Response;
import com.android.volley.VolleyError;
import com.android.volley.toolbox.StringRequest;
import com.android.volley.toolbox.Volley;
public class MainActivity5 extends AppCompatActivity {
private static final String fd = MainActivity5.class.getSimpleName();
private String url = "https://api.thingspeak.com/channels/ 2046669/feeds.json?api_key=ABCABCABACXYZ&results=10";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main5);
// Instantiate the RequestQueue
RequestQueue queue = Volley.newRequestQueue(this);
Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
new Response. Listener<String>() {
@Override
public void onResponse(String response) {
// Display the response string.
Log.d(fd, "Response: " + response);
// Parse the response string and display the data in your app's UI.
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
// Handle error
Log.e(fd, "Error: " + error.toString());
}
});
// Add the request to the RequestQueue
queue.add(stringRequest);
}
}
