"How to fix this post HTTP request using Android Studio?"

Question

I'm trying to post HTTP request to my web application. But there is no action done. Where am I wrong?

class AsyncT extends AsyncTask<Void,Void,Void> {
    @Override
    protected Void doInBackground(Void... params){
        try{
            String url1 = "http://172.26.1.1/data/omnidrive";
            URL url = new URL(url1);
            HttpURLConnection httpURLConnection = 
            (HttpURLConnection)url.openConnection();
            httpURLConnection.setDoOutput(true);
            httpURLConnection.setRequestMethod("POST");
            httpURLConnection.connect();
            String data = "[0.10,0.00,0.00]";

            DataOutputStream wr = new           
            DataOutputStream(httpURLConnection.getOutputStream());
            wr.writeBytes(data);
            wr.flush();
            wr.close();
        } catch (MalformedURLException e){
            e.printStackTrace();
        } catch(IOException e){
            e.printStackTrace();
        }
        return null;
    }
}

I expected the data to be updated in the web application.

This is what it shows after I clicked the button

Error

W/Settings: Setting device_provisioned has moved from android.provider.Settings.Secure to android.provider.Settings.Global. V/HiTouch_HiTouchSensor: User setup is finished.

Try this one might help you.
First of create one Folder under res folder named it xml then in that folder create one xml file name network_security_config.

Then Add below lines of code in that xml file.

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">your url</domain>
    </domain-config>
</network-security-config>

Then below line in application tag in Manifest file.

android:networkSecurityConfig="@xml/network_security_config"

Use should declare android:usesCleartextTraffic="true" inside XML application tag. It is used to indicate whether the app intends to use cleartext network traffic, such as cleartext HTTP. For more information, please visit this site: https://developer.android.com/guide/topics/manifest/application-element#usesCleartextTraffic
