BroadcastReceiver無法檢測/讀取短信

Question

我正在構建一個應用程序，可以讀取傳入的短信。但是，我的BroadcastReceiver類無法檢測/讀取傳入的SMS。我認爲我的代碼是正確的，但仍然無法正常工作。

這裏是我的代碼：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

</application> 

[JAVA CLASS]

public class SmsReceiver extends BroadcastReceiver { 

private static final String SMS_BUNDLE = "pdus"; 
private String smsBody, address; 

@Override 
public void onReceive(Context context, Intent intent) { 

    Toast.makeText(context,"Test",Toast.LENGTH_LONG); 
} 



public void showNotification(Context context) { 
    Vibrator v = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE); 

    PendingIntent contentIntent = PendingIntent.getActivity(context, 0, 
      new Intent(context, MapsActivity.class), 0); 

    v.vibrate(500); 
    Intent in = new Intent("SmsMessage.intent.MAIN"). 
      putExtra("get_msg", address + ":" + smsBody); 
    context.sendBroadcast(in); 

    NotificationCompat.Builder mBuilder = 
      new NotificationCompat.Builder(context) 
        //.setSmallIcon(R.drawable.notif1) 
        .setContentTitle("Attention!") 
        .setContentText("Car crash occure."); 
    mBuilder.setContentIntent(contentIntent); 
    mBuilder.setDefaults(Notification.DEFAULT_SOUND); 
    mBuilder.setAutoCancel(true); 
    NotificationManager mNotificationManager = 
      (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE); 
    mNotificationManager.notify(1, mBuilder.build()); 

} 

}

我想你忘了把.show()在吐司結束。

Toast.makeText(context, "Test" ,Toast.LENGTH_LONG).show();
