I'm currently try to implement a two factor authentication system on a project i'm working on using twilio as a sms gateway service to request a random login token and then send it to the user as a text message. I followed the tutorial found here "https://www.twilio.com/blog/2016/05/how-to-send-an-sms-from-android.html" to test the service out. Following the tutorial I hosted the backend on Heroku. The app works just fine and says that the sms has been sent. However I never receive it. Any help would great.
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import android.content.Context;
import java.io.IOException;
import okhttp3.Call;
import okhttp3.Callback;
import okhttp3.FormBody;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;
public class MainActivity extends AppCompatActivity {
private EditText mTo;
private EditText mBody;
private Button mSend;
private OkHttpClient mClient = new OkHttpClient();
private Context mContext;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTo = (EditText) findViewById(R.id.txtNumber);
mBody = (EditText) findViewById(R.id.txtMessage);
mSend = (Button) findViewById(R.id.btnSend);
mSend.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
try {
post(" https://cryptic-shore-79857.herokuapp.com", new
Callback(){
@Override
public void onFailure(Call call, IOException e) {
e.printStackTrace();
}
@Override
public void onResponse(Call call, Response response)
throws IOException {
runOnUiThread(new Runnable() {
@Override
public void run() {
mTo.setText("");
mBody.setText("");
Toast.makeText(getApplicationContext(),"SMS Sent!",Toast.LENGTH_SHORT).show();
}
});
}
});
} catch (IOException e) {
e.printStackTrace();
}
}
});
mContext = getApplicationContext();
}
Call post(String url, Callback callback) throws IOException {
RequestBody formBody = new FormBody.Builder()
.add("To", mTo.getText().toString())
.add("Body", mBody.getText().toString())
.build();
Request request = new Request.Builder()
.url(url)
.post(formBody)
.build();
Call response = mClient.newCall(request);
response.enqueue(callback);
return response;
}
}
I'm thinking the URL that connects to Heroku is incorrect but I have no idea what it should be.
