How to send sms using Twillio Api in Android. Here is my code. What I don't know is how to set http request body. When I test it using CocoaRestClient(a tool for api test), it is working well. Help me please.
public void sendInviteSMS(String kToNumber) {
int random4Num = generateRequestCode();
...
String kTwilioSID = "...";
String kTwilioSecret = "...";
String kFromNumber = "...";
String message = String.format("%s has sent you a invite. To accept, enter the following code: %d.", AppUtil.sharedObject().userFirstName, random4Num);
String kMessage = message;
String urlString = String.format("https://%s:%s@api.twilio.com/2010-04-01/Accounts/%s/SMS/Messages", kTwilioSID, kTwilioSecret, kTwilioSID);
HashMap postData = new HashMap();
postData.put("From", kFromNumber);
postData.put("To", kToNumber);
postData.put("Body", kMessage);
// Validate user with the POST call
AsyncTask doPost = new TwilioPost(urlString) {
@Override
protected void onPostExecute(String result) {
Log.v("PHONE", result);
}
}.execute(postData);
}
...
public class TwilioPost extends AsyncTask<HashMap<String, String>, Void, String> {
private String remoteURL;
private static final String TAG = "Wayjer";
public TwilioPost(String remoteURL) {
this.remoteURL = remoteURL;
}
