How to send SMS using Twilio in my android application?

Question

In my android application I have created one button, when I had pressed on the button I want to send message.So for that I have created one java class and written twilio cod

Answer 1

You should use the BasicPhone project of Twilio SDK. I've tried this to call and now I can call too. This project has all the methods and functions that you need to call and to send SMS. First of all, you need a PHP web service to get capability token and pass that PHP script into your app.

This is how I solved my need. public class TwilioAsyncTask extends AsyncTask {

        Context context;
        ProgressDialog progressDialog;


        public TwilioAsyncTask(Context context) {
            this.context = context;
        }

        @Override
        protected String doInBackground(String... strings) {

            //
            HttpClient httpclient = new DefaultHttpClient();

            HttpPost httppost = new HttpPost(
                    "https://api.twilio.com/2010-04-01/Accounts/AC_yourACCOUNT_SID_9b/SMS/Messages");
            String base64EncodedCredentials = "Basic "
                    + Base64.encodeToString(
                    (ACCOUNT_SID + ":" + AUTH_TOKEN).getBytes(),
                    Base64.NO_WRAP);

            httppost.setHeader("Authorization",
                    base64EncodedCredentials);
            try {

                int randomPIN = (int) (Math.random() * 9000) + 1000;
                String randomVeriValue = "" + randomPIN;
// these are for control in other anctivity used sharepreference 
                editorTwilio.putString("twilio_veri_no", randomVeriValue);
                editorTwilio.commit();

                List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
                nameValuePairs.add(new BasicNameValuePair("From",
                        "+148******")); // what number they gave you
                nameValuePairs.add(new BasicNameValuePair("To",
                        "+90" + phoneNo)); // your phone or our customers
                nameValuePairs.add(new BasicNameValuePair("Body",
                        "Your verification number is : " + randomVeriValue));

                httppost.setEntity(new UrlEncodedFormEntity(
                        nameValuePairs));

                // Execute HTTP Post Request
                HttpResponse response = httpclient.execute(httppost);
                HttpEntity entity = response.getEntity();
                System.out.println("Entity post is: "
                        + EntityUtils.toString(entity));
                // Util.showMessage(mParentAct, "Welcome");


            } catch (ClientProtocolException e) {

            } catch (IOException e) {

            }

            //
            return "Executed";
        }

        @Override
        protected void onPostExecute(String result) {
            // execution of result of Long time consuming operation
            //progressDialog.dismiss();
        }


        @Override
        protected void onPreExecute() {

            progressDialog = ProgressDialog.show(context, "", " Wait for ");

        }


        @Override
        protected void onProgressUpdate(String... text) {
            // Things to be done while execution of long running operation is in
            // progress. For example updating ProgessDialog
        }

    }


    And call your Task


TwilioAsyncTask task = new TwilioAsyncTask(CountryAndPhone.this);
                        task.execute();

Answer 3

My method, using OkHttp:

1. Prerequisites

Gradle:

dependencies {    
    compile 'com.squareup.okhttp3:okhttp:3.4.1'
}

Manifest:

<uses-permission android:name="android.permission.INTERNET"/>

Permission in activity:

if (android.os.Build.VERSION.SDK_INT > 9) {
    StrictMode.setThreadPolicy( new StrictMode.ThreadPolicy.Builder().permitAll().build() );
}

2. Code

private void sendSms(String toPhoneNumber, String message){
    OkHttpClient client = new OkHttpClient();
    String url = "https://api.twilio.com/2010-04-01/Accounts/"+ACCOUNT_SID+"/SMS/Messages";
    String base64EncodedCredentials = "Basic " + Base64.encodeToString((ACCOUNT_SID + ":" + AUTH_TOKEN).getBytes(), Base64.NO_WRAP);

    RequestBody body = new FormBody.Builder()
            .add("From", fromPhoneNumber)
            .add("To", toPhoneNumber)
            .add("Body", message)
            .build();

    Request request = new Request.Builder()
            .url(url)
            .post(body)
            .header("Authorization", base64EncodedCredentials)
            .build();
    try {
        Response response = client.newCall(request).execute();
        Log.d(TAG, "sendSms: "+ response.body().string());
    } catch (IOException e) { e.printStackTrace(); }

}

I used Allu code for generathing authorization in header

This solution with Retrofit

public static final String ACCOUNT_SID = "accountSId";
public static final String AUTH_TOKEN = "authToken";

private void sendMessage() {
    String body = "Hello test";
    String from = "+...";
    String to = "+...";

    String base64EncodedCredentials = "Basic " + Base64.encodeToString(
            (ACCOUNT_SID + ":" + AUTH_TOKEN).getBytes(), Base64.NO_WRAP
    );

    Map<String, String> data = new HashMap<>();
    data.put("From", from);
    data.put("To", to);
    data.put("Body", body);

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl("https://api.twilio.com/2010-04-01/")
            .build();
    TwilioApi api = retrofit.create(TwilioApi.class);

    api.sendMessage(ACCOUNT_SID, base64EncodedCredentials, data).enqueue(new Callback<ResponseBody>() {
        @Override
        public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
            if (response.isSuccessful()) Log.d("TAG", "onResponse->success");
            else Log.d("TAG", "onResponse->failure");
        }

        @Override
        public void onFailure(Call<ResponseBody> call, Throwable t) {
            Log.d("TAG", "onFailure");
        }
    });
}

interface TwilioApi {
    @FormUrlEncoded
    @POST("Accounts/{ACCOUNT_SID}/SMS/Messages")
    Call<ResponseBody> sendMessage(
            @Path("ACCOUNT_SID") String accountSId,
            @Header("Authorization") String signature,
            @FieldMap Map<String, String> metadata
    );
}

Dependencies for build.gradle
compile 'com.squareup.retrofit2:retrofit:2.1.0'

Answer 5

Twilio Java SDK has third party dependencies without them it is not going to work. The dependencies are: 1. Httpcore 2. Httpclient 3. Commons lang 4. Json simple 5. Jackson Not quite sure if you need them all, but at least now you are missing httpcore

Answer 6

I have used HttpPost method to send sms in that i have passed my url with base authentication here is my code

HttpClient httpclient = new DefaultHttpClient();

HttpPost httppost = new HttpPost(
                            "https://api.twilio.com/2010-04-01/Accounts/{ACCOUNT_SID}/SMS/Messages");
        String base64EncodedCredentials = "Basic "
                            + Base64.encodeToString(
                                    (ACCOUNT_SID + ":" + AUTH_TOKEN).getBytes(),
                                    Base64.NO_WRAP);

                    httppost.setHeader("Authorization",
                            base64EncodedCredentials);
                    try {

                        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
                        nameValuePairs.add(new BasicNameValuePair("From",
                                "+123424353534"));
                        nameValuePairs.add(new BasicNameValuePair("To",
                                "+914342423434"));
                        nameValuePairs.add(new BasicNameValuePair("Body",
                                "Welcome to Twilio"));

                        httppost.setEntity(new UrlEncodedFormEntity(
                                nameValuePairs));

                        // Execute HTTP Post Request
                        HttpResponse response = httpclient.execute(httppost);
                        HttpEntity entity = response.getEntity();
                        System.out.println("Entity post is: "
                                + EntityUtils.toString(entity));


                    } catch (ClientProtocolException e) {

                    } catch (IOException e) {

                    }
                }

It is working well.
