I'm trying to create an app which will send some data to a web server when a button will be clicked and the data will be from the form. The data types are first name, last name and others. I'm a beginner developer and trying OKHTTPFClient plugin for sending HTTP request from the app. What I need is on click the form data will be send to the PHP and then PHP will give a success response which will then the app get and then the activity will be redirected to thank you activity. Here's the code I'm trying now -
submitRequest.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
if ( firstName.getText().toString().length() == 0 ) {
firstName.setError("Please enter your first name!");
}
if ( firstName.getText().toString().length() != 0 ) {
Toast.makeText(getApplicationContext(), firstName.getText().toString(), Toast.LENGTH_SHORT).show();
requestHTTP(firstName.getText().toString());
} else {
}
}
});
And here is the method for OKHTTPClient -
private void requestHTTP(String first_name) {
OkHttpClient httpClient = new OkHttpClient();
String url = "https://www.example.com/action.php";
RequestBody formBody = new FormBody.Builder()
.add("first_name", first_name)
.build();
Request request = new Request.Builder()
.url(url)
.post(formBody)
.build();
Response response = null;
try {
response = httpClient.newCall(request).execute();
if (response.isSuccessful()) {
Toast.makeText(getApplicationContext(), firstName.getText().toString(), Toast.LENGTH_SHORT).show();
}
} catch (IOException e) {
}
}
UPDATE :
Here's the errors showing on Android Run section -

You should use THREAD .
//A thread is a thread of execution in a program.
// The Java Virtual Machine allows an application to have multiple threads of execution running concurrently.
Thread thread = new Thread(new Runnable() {
@Override
