I write a app which use SMS Manager. I use method sendTextMessage() but it isn't work. Now I am using sendMutlipartTextMessage() and it's work. But it's send multipart message when it is about 60 characters. This is normal? Everywhere I read than should be 160 characters. This is important to me because I must pay more.

回答1:
The message character limit depends on the character bit-size of the alphabet you're using. For the standard GSM 7-bit alphabet, the character limit is 160. For an 8-bit alphabet, it is 140, and for a 16-bit alphabet, which sounds like your situation, it is only 70 characters. If you must send messages with special Unicode characters, like those in non-Latin alphabets, then you're stuck with the 16-bit alphabet, and its 70-character limit. If you can somehow convert the messages to the basic 7-bit alphabet, you will have the 160-character limit.

I add my SMS method if it can help someone.
//TO USE EveryWhere
SMSUtils.sendSMS(context, phoneNumber, message); //Manifest
//JAVA
public class SMSUtils extends BroadcastReceiver { public static final String SENT_SMS_ACTION_NAME = "SMS_SENT"; public static final String DELIVERED_SMS_ACTION_NAME = "SMS_DELIVERED"; @Override public void onReceive(Context context, Intent intent) { //Detect l'envoie de sms if (intent.getAction().equals(SENT_SMS_ACTION_NAME)) { switch (getResultCode()) { case Activity.RESULT_OK: // Sms sent Toast.makeText(context, context.getString(R.string.sms_send), Toast.LENGTH_LONG).show(); break; case SmsManager.RESULT_ERROR_GENERIC_FAILURE: // generic failure Toast.makeText(context, context.getString(R.string.sms_not_send), Toast.LENGTH_LONG).show(); break; case SmsManager.RESULT_ERROR_NO_SERVICE: // No service Toast.makeText(context, context.getString(R.string.sms_not_send_no_service), Toast.LENGTH_LONG).show(); break; case SmsManager.RESULT_ERROR_NULL_PDU: // null pdu Toast.makeText(context, context.getString(R.string.sms_not_send), Toast.LENGTH_LONG).show(); break; case SmsManager.RESULT_ERROR_RADIO_OFF: //Radio off Toast.makeText(context, context.getString(R.string.sms_not_send_no_radio), Toast.LENGTH_LONG).show(); break; } } //detect la reception d'un sms else if (intent.getAction().equals(DELIVERED_SMS_ACTION_NAME)) { switch (getResultCode()) { case Activity.RESULT_OK: Toast.makeText(context, context.getString(R.string.sms_receive), Toast.LENGTH_LONG).show(); break; case Activity.RESULT_CANCELED: Toast.makeText(context, context.getString(R.string.sms_not_receive), Toast.LENGTH_LONG).show(); break; } } } /** * Test if device can send SMS * @param context * @return */ public static boolean canSendSMS(Context context) { return context.getPackageManager().hasSystemFeature(PackageManager.FEATURE_TELEPHONY); } public static void sendSMS(final Context context, String phoneNumber, String message) { if (!canSendSMS(context)) { Toast.makeText(context, context.getString(R.string.cannot_send_sms), Toast.LENGTH_LONG).show(); return; } PendingIntent sentPI = PendingIntent.getBroadcast(context, 0, new Intent(SENT_SMS_ACTION_NAME), 0); PendingIntent deliveredPI = PendingIntent.getBroadcast(context, 0, new Intent(DELIVERED_SMS_ACTION_NAME), 0); final SMSUtils smsUtils = new SMSUtils(); //register for sending and delivery context.registerReceiver(smsUtils, new IntentFilter(SMSUtils.SENT_SMS_ACTION_NAME)); context.registerReceiver(smsUtils, new IntentFilter(DELIVERED_SMS_ACTION_NAME)); SmsManager sms = SmsManager.getDefault(); ArrayList parts = sms.divideMessage(message); ArrayList sendList = new ArrayList(); sendList.add(sentPI); ArrayList deliverList = new ArrayList(); deliverList.add(deliveredPI); sms.sendMultipartTextMessage(phoneNumber, null, parts, sendList, deliverList); //we unsubscribed in 10 seconds new Handler().postDelayed(new Runnable() { @Override public void run() { context.unregisterReceiver(smsUtils); } }, 10000); } }
