Need to send data from android app to ubidots when a button is pressed.
Similar issue(but not resolved yet)
[SOLVED] How to send data to ubidots using a tooggle button on android studio?
Greetings, have you already tried to capture the press button and to trigger a callback function that sends data to Ubidots? You can find an example of a function for sending data using JAVA here.
All the best
LightOn = findViewById(R.id.buttonId_lightOn);
LightOff = findViewById(R.id.buttonId_lightOff);
LightOn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
ApiClient apiClient = new ApiClient("xxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
Variable device1 = apiClient.getVariable("xxxxxxxxxxxxxxxxxxx");
device1.saveValue(1);
}
});
LightOff.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
ApiClient apiClient = new ApiClient("xxxxxxxxxxxxxxxxxxx");
Variable device1 = apiClient.getVariable("xxxxxxxxxxxxxxxxxxx");
device1.saveValue(0);
}
});
This is my java code, When i run this code the application crashes
I read in some post that the API is outdated. If so how to achieve the same using HTPP/MQTT request from android studio?
Greetings, the API is not oudated but the library yes, so my advise is to make the POST request using the previous Java example that I shared with you.

It would be much appreciated if you could help me to combine Java example with my code.
I tried a few ways but it didn’t work out.
I wrote some code to do simple http request. I its working with other link ( like when i try to gpio of NodeMCU http://192.168.1.4/LED=ON).
But when i replace that link with ubidots its not working.
Here is my code
public class MainActivity extends AppCompatActivity {
Button LightOn, LightOff;
TextView textView;
String url ="https://industrial.ubidots.com/api/v1.6/devices/spatez/?token=xxxxxxxxxx&_method=post&device2=1";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LightOn = findViewById(R.id.buttonIdLightOn);
LightOff = findViewById(R.id.buttonIdLightOff);
textView = findViewById(R.id.textView);
LightOn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// Instantiate the RequestQueue.
final RequestQueue queue = Volley.newRequestQueue(MainActivity.this);
// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
// Display the first 500 characters of the response string.
// textView.setText(response);
queue.stop();
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
// textView.setText("Error");
error.printStackTrace();
queue.stop();
}
});
// Add the request to the RequestQueue.
queue.add(stringRequest);
}
});
}
}
Solved, here is my code. If anyone is having a similar issue.
public class MainActivity extends AppCompatActivity
{
private static final String TAG = MainActivity.class.getName() ;
Button LightOn, LightOff;
TextView textView;
private RequestQueue mRequestQueue;
private StringRequest stringRequest;
private static String deviceLabel = "xxxxxxxxxxx";
private static String variableLabel = "xxxxxxxxx";
private static String token = "xxxxxxxxxxxxxxxx";
private static String endpoint = "https://industrial.api.ubidots.com/api/v1.6/devices";
private static String userAgent = "Java/0.1";
private static String value = "1";
private String url = "https://industrial.ubidots.com/api/v1.6/devices/xxxxxxx/?token=xxxxxxxxx&_method=post&xxxxxxxxx=1";
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LightOn = findViewById(R.id.buttonIdLightOn);
LightOff = findViewById(R.id.buttonIdLightOff);
textView = findViewById(R.id.textView);
LightOn.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View view)
{
sendRequestAndPrintResponse();
}
});
}
private void sendRequestAndPrintResponse()
{
mRequestQueue = Volley.newRequestQueue(this);
stringRequest = new StringRequest(Request.Method.GET, url, new Response.Listener<String>()
{
@Override
public void onResponse(String response)
{
Log.i(TAG,"Response : " + response.toString());
}
},new Response.ErrorListener()
{
@Override
public void onErrorResponse(VolleyError error)
{
Log.i(TAG,"Error" + error.toString());
}
});
mRequestQueue.add(stringRequest);
}
}
