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

My method, using OkHttp:

1. Prerequisites

Gradle:

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

Manifest:

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
