Two ways to send SMS to Android

First: Call the system SMS interface to send text messages directly; The main code is as follows:

/*** Direct SMS Interface Text message * *@paramPhoneNumber *@parammessage*/     Public voidsendsms (String phonenumber, String message) {//Get SMS ManagerAndroid.telephony.SmsManager Smsmanager =Android.telephony.SmsManager. Getdefault (); //Split SMS content (SMS length limit)List<string> dividecontents =smsmanager.dividemessage (message);  for(String text:dividecontents) {smsmanager.sendtextmessage (PhoneNumber,NULL, text, SENTPI, DELIVERPI); }    }

Second: To set up the system to send SMS functions; The main code is as follows:

 /**   * system Text message function *   @param   PhoneNumber *   @param  Span style= "color: #008000;" > message  */ public  void   Dosendsmsto (String phonenumber,string message) { if   (Phonenumberutils.isglobalphonenumber (PhoneNumber)) {Intent Intent = new  Intent (intent.action_sendto, Uri.parse ("Smsto:" +phonenumber));                      Intent.putextra ( "sms_body" , message);        StartActivity (Intent); }    }

Here is the first method, the first method can monitor the sending status and the receiver status of the use of more.

The status codes returned by the processing are as follows:

　　

//processing the Sent status returnedString sent_sms_action = "Sent_sms_action"; Intent sentintent=NewIntent (sent_sms_action); SENTPI= Pendingintent.getbroadcast ( This, 0, Sentintent,0); //Register the broadcast receivers         This. Registerreceiver (NewBroadcastreceiver () {@Override Public voidonreceive (Context _context, Intent _intent) {Switch(Getresultcode ()) { CaseActivity.RESULT_OK:Toast.makeText (mainactivity. This,                "SMS sent Successfully", Toast.length_short). Show ();  Break;  Casesmsmanager.result_error_generic_failure: Break;  CaseSmsmanager.result_error_radio_off: Break;  CaseSMSMANAGER.RESULT_ERROR_NULL_PDU: Break; }            }        }, NewIntentfilter (sent_sms_action)); //processing the received status returnedString delivered_sms_action = "Delivered_sms_action"; //Create the Deilverintent parameterIntent deliverintent =NewIntent (delivered_sms_action); Deliverpi= Pendingintent.getbroadcast ( This, 0, Deliverintent,0);  This. Registerreceiver (NewBroadcastreceiver () {@Override Public voidonreceive (Context _context, Intent _intent) {toast.maketext (mainactivity. This,          "The addressee has successfully received the message.", Toast.length_short). Show (); }        }, NewIntentfilter (delivered_sms_action));

Don't forget the question of permissions:
<uses-permission android:name= "Android.permission.SEND_SMS"/>
