IntentService + SmsManager沒有得到onReceive調用registeredReceivers

Question

我有一個IntentService用於通過SmsManager異步發送文本消息給人。我面臨的問題是，我註冊的服務是在完成這兩項操作中的任何一項時，發送/發送接收器以偵聽。這裏是我的代碼：

public static final String SENT = "SMS_SENT"; 
private int mPartCounter; 

public SendTextService(String name){ 
    super(name); 
} 

public SendTextService(){ 
    super(SendTextService.class.getSimpleName()); 
} 

@Override 
protected void onHandleIntent(Intent intent) { 
    mMessage = intent.getStringExtra(MESSAGE_CONTENT); 
    mNumbers = intent.getStringArrayExtra(MESSAGE_CONTACTS); 
    registerReceivers(); 
    sendMessage(); 
} 

private void sendMessage(String message, String number){ 
    SmsManager smsManager = SmsManager.getDefault(); 
    ArrayList<String> splitMessage = smsManager.divideMessage(message); 
    mPartCounter = splitMessage.size(); 

    /* Handle multipart messages */ 
    ArrayList<PendingIntent> sendIntents = new ArrayList<>(); 
    ArrayList<PendingIntent> deliverIntents = new ArrayList<>(); 
    PendingIntent sendIntent = PendingIntent.getBroadcast(this, 0, new Intent("SMS_SENT"), 0); 
    PendingIntent deliverIntent = PendingIntent.getBroadcast(this, 0, new Intent("SMS_DELIVERED"), 0); 

    /* Add a PendingIntent for send/deliver for each part needed */ 
    for(int i=0; i<mPartCounter; ++i) { 
     sendIntents.add(sendIntent); 
     deliverIntents.add(deliverIntent); 
    } 

    /* Send the messages in either multi-parts or single */ 
    smsManager.sendTextMessage(number, null, message, sendIntent, deliverIntent); 
} 

private void registerReceivers(){ 
    registerReceiver(new BroadcastReceiver() { 
     @Override 
     public void onReceive(Context arg0, Intent arg1) { 
      switch (getResultCode()) { 
       case Activity.RESULT_OK: 
        Toast.makeText(getBaseContext(), "SMS sent", Toast.LENGTH_SHORT).show(); 
        break; 

       default: 
        Toast.makeText(getBaseContext(), "SMS sending failed", Toast.LENGTH_SHORT).show(); 
        break; 
      } 
     } 
    }, new IntentFilter(SENT)); 
} 

我設置了斷點，代碼永遠不會在這裏，但消息確實發送？任何人都看到了問題？

哦一切，我通過我自己的接收開始我的服務：

static public class MessageReceiver extends BroadcastReceiver{ 

    @Override 
    public void onReceive(Context context, Intent intent) { 
     Intent textService = new Intent(context, SendTextService.class); 
     textService.putExtra(MESSAGE_CONTENT, intent.getStringExtra(MESSAGE_CONTENT)); 
     textService.putExtra(MESSAGE_CONTACTS, intent.getStringArrayExtra(MESSAGE_CONTACTS)); 
     context.startService(textService); 
    } 
} 

而且在我的AndroidManifest.xml中都定義：

<service android:name=".service.SendTextService"/> 
<receiver android:name=".service.SendTextService$MessageReceiver"/> 

這是我打電話給我的接收器：

Intent broadcastIntent = new Intent(SendActivity.this, SendTextService.MessageReceiver.class); 
broadcastIntent.putExtra(SendTextService.MESSAGE_CONTACTS, mNumbers); 
broadcastIntent.putExtra(SendTextService.MESSAGE_CONTENT, mBodyEdit.getText().toString()); 
sendBroadcast(broadcastIntent); 

Logcat有這個輸出，但這是因爲我試圖取消註冊他們，當我看到他們都是森的...但檢測發生在接收器用於處理SNET消息（這就是爲什麼我有這個問題了）：

Answer 1

IntentService小號幾乎只要onHandleIntent()方法結束自行停止。您正在收到關於泄露的Receiver的日誌消息，因爲您尚未在發生此事件之前取消註冊Receiver，因爲您使用的是匿名Receiver實例，所以您無法真正對代碼執行此操作。

如果要動態註冊Receiver，則需要在組件中這樣做，該組件將一直運行，直到發送廣播;例如在Activity或常規的Service中。

您也可以靜態地註冊在清單中的接收器，因爲你已經與MessageReceiver完成，將開始在廣播火災，無論您IntentService運行與否，而是你需要指定一個<intent-filter>它在清單中，如果您使用隱式Intent。例如：

<receiver android:name=".service.SendTextService$SentReceiver"> 
    <intent-filter> 
     <action android:name="SMS_SENT" /> 
    </intent-filter> 
</receiver> 

否則，你可以使用一個明確的Intent - 一個指定的接收器類 - 和省略過濾器。這可能是首選方法，因爲其他應用程序的Receiver沒有機會獲得廣播。如果您在清單中靜態註冊Receiver，則不需要動態註冊它。

此外，您不需要向接收方廣播以啓動您的IntentService。您可以直接啓動服務，並附帶Intent所需的附加服務。也就是說，你的MessageReceiver並不是真的有必要。
