使用AlarmManager发送呼叫记录

Question

我正在开发一个使用短信以编程方式发送呼叫记录的应用程序。但是当我在模拟器中有两个或更多历史记录时，sendMultipartTextMessage不起作用并且短信不发送。如果有人知道如何，请帮帮我。

public void onReceive(Context context, Intent intent){

    StringBuffer sb = new StringBuffer(); 
    Cursor managedCursor = context.getContentResolver().query(CallLog.Calls.CONTENT_URI, null, null, null, null); 
    int number = managedCursor.getColumnIndex(CallLog.Calls.NUMBER); 
    int type = managedCursor.getColumnIndex(CallLog.Calls.TYPE);
    int date = managedCursor.getColumnIndex(CallLog.Calls.DATE); 
    int duration = managedCursor.getColumnIndex(CallLog.Calls.DURATION); 
    sb.append("Call Log :");
    while (managedCursor.moveToNext()) { 
        String phNumber = managedCursor.getString(number);
        String callType = managedCursor.getString(type); String callDate = managedCursor.getString(date); 
        Date callDayTime = new Date(Long.valueOf(callDate));
        String callDuration = managedCursor.getString(duration);
        String dir = null;
        int dircode = Integer.parseInt(callType); 
        switch (dircode) { 
        case CallLog.Calls.OUTGOING_TYPE: dir = "OUTGOING"; 
        break;
        case CallLog.Calls.INCOMING_TYPE: dir = "INCOMING"; 
        break;
        case CallLog.Calls.MISSED_TYPE: dir = "MISSED"; 
        break; } 
        sb.append(" :-" + phNumber );// "-" + dir +" ");
    //  + callDayTime + " " + callDuration);
        //sb.append("\n----------------------------------"); 
        managedCursor.close(); 
    }
        histo = sb.toString() ;
        srte ="5554";

        if(histo.length()>=160){
            SmsManager manager = SmsManager.getDefault() ;
            ArrayList<String> sms = manager.divideMessage(histo);
            manager.sendMultipartTextMessage(srte, null, sms, null, null);
            //Toast.makeText(context, "Message enoyer", Toast.LENGTH_LONG).show();
        }
        else {

            SmsManager manager = SmsManager.getDefault();
            manager.sendTextMessage(srte, null, histo, null, null);
        //  Toast.makeText(context, "Message enoyer", Toast.LENGTH_LONG).show();
        }
