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 code.

final TwilioRestClient client = new TwilioRestClient(
                        ACCOUNT_SID, AUTH_TOKEN);

                // Get the main account (The one we used to authenticate the
                // client)
                final Account mainAccount = client.getAccount();

                final SmsFactory messageFactory = mainAccount.getSmsFactory();
                final Map<String, String> messageParams = new HashMap<String, String>();
                messageParams.put("To", "+912342423423");
                messageParams.put("From", "+132432432434");
                messageParams.put("Body", "This is my message");
                try {
                    messageFactory.create(messageParams);
                } catch (TwilioRestException e) {
                    e.printStackTrace();
                }

when I am using the above code it showing some error like java.lang.NoSuchMethodError: org.apache.http.impl.conn.tsccm.ThreadSafeClientConnManager

I have added only one jar file in lib folder as " twilio-java-sdk-3.3.10-jar-with-dependencies.jar ".

please tell me what can I do?

Answer 1

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'
