BroadcastReceiver的生命周期和操作我不清楚,我已经看过android帮助库,但仍然不清楚,考虑下面的例子:
private void sendSMS(final MessageInfo MI) {
String SENT = "SMS_SENT" ;
PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, new Intent(
SENT), 0);
// ---when the SMS has been sent---
registerReceiver(new BroadcastReceiver() {
@Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode()) {
case Activity.RESULT_OK:
Confirm(MI);
break;
case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Toast.makeText(getBaseContext(), "שליחה נכשלה",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NO_SERVICE:
Toast.makeText(getBaseContext(), "שליחה נכשלה, אין רשת",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NULL_PDU:
Toast.makeText(getBaseContext(), "Null PDU",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_RADIO_OFF:
Toast.makeText(getBaseContext(), "שליחה נכשלה, מצב טיסה",
Toast.LENGTH_SHORT).show();
break;
}
}
}, new IntentFilter(SENT));
SmsManager sms = SmsManager.getDefault();
ArrayList<String> parts = sms.divideMessage(MI.Message());
int numParts = parts.size();
ArrayList<PendingIntent> sentIntents = new ArrayList<PendingIntent>();
for (int i = 0; i < numParts; i++) {
sentIntents.add(sentPI);
}
sms.sendMultipartTextMessage(MI.Phone(), null, parts, sentIntents, null);
}
}
如果我发送大量消息怎么办,它会为每条消息创建一个 BroadcastReceiver 吗?当发送的确认返回时,是异步返回还是同步返回?BroadcastReceiver 会自动注销,还是需要手动完成?
我会很感激任何帮助,我希望我很清楚。
顺便说一句,Confirm 函数向服务器发送确认(异步),MI 类是 MessageInfo(phone,body,ID)
