防止短信进入收件箱？

Question

我已经阅读了大部分关于阻止 SMS 进入收件箱的问题。没有什么对我有用。所以，我现在有两个应用程序，一个是发送，另一个是接收器。接收者需要检查消息的前四个字符，如果它来自发件人应用程序。然后，阻止它进入收件箱。 他们说我必须提高应用程序的优先级。我做了，这是我的清单

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <receiver android:name=".SmsReceiver"> 
        <intent-filter android:priority="100"> 
            <action android:name=
                "android.provider.Telephony.SMS_RECEIVED" />
        </intent-filter> 
    </receiver>

</application>
    <uses-permission android:name="android.permission.READ_SMS"></uses-permission>
    <uses-permission android:name="android.permission.SEND_SMS"></uses-permission>
    <uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>

并且，为了清楚起见，这是我检查消息的活动。

 public void onReceive(Context context, Intent intent) 
 {

   //---get the SMS message passed in---
      final Bundle bundle = intent.getExtras();
        try {

            if (bundle != null) {

                final Object[] pdusObj = (Object[]) bundle.get("pdus");

                for (int i = 0; i < pdusObj.length; i++) {

                    SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                    String phoneNumber = currentMessage.getDisplayOriginatingAddress();

                    String senderNum = phoneNumber;
                    message = currentMessage.getDisplayMessageBody();

                    Log.i("SmsReceiver", "senderNum: "+ senderNum + "; message: " + message);

                    H = currentMessage.getMessageBody(); 
                   // Show Alert
                    int duration = Toast.LENGTH_LONG;
                    Toast toast = Toast.makeText(context, 
                                 "senderNum: "+ senderNum + ", message: " + message, duration);

                    toast.show();
                    if(i==0)
                        H = currentMessage.getMessageBody(); 


                } // end for loop
              } // bundle is null

        } catch (Exception e) {
            Log.e("SmsReceiver", "Exception smsReceiver" +e);

        }

        check_message = message_checked(H) ; 

       //---display the new SMS message---
        if(check_message)
        {
       Intent intentHome = new Intent(context,MainActivity.class);
       intentHome.putExtra("msgContent", message);

       intentHome.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
       context.startActivity(intentHome);
        }
        else 
            System.exit(0); 

   }                         

public boolean message_checked(String the_message)
{
String Code = new String("*%#&"); 
String four_char = "" ; 
for(int i = 0 ; i<4 ; i++)
{
    four_char += the_message.charAt(i) ; 

}
if(four_char.equals(Code))
{
    this.abortBroadcast();

    return true;
}
else 
    return false ; 



}

我做错了吗？如果我这样做了，错误在哪里。尽管该应用程序正在按我的意愿运行，但我仍然在收件箱中收到短信。

这就是我过去的做法，抱歉我的模拟器现在无法工作，所以我无法检查。希望有帮助。

  public void onReceive(Context context, Intent intent) {

                if(intent.getAction().equalsIgnoreCase("android.provider.Telephony.SMS_RECEIVED")){

                        // Check if the SMS matches our SOS message
                        SmsMessage[] messages = getMessagesFromIntent(intent);
                        if(messages != null){
                                for(int i = 0; i < messages.length; i++){
                                        SmsMessage message = messages[i];
                                        if(matchesMessage(context,message.getDisplayMessageBody())){
                                                Log.i(LOGNAME, "Received Test String! Abort Broadcast");
                                //put intent call or preferred code here

                                                this.abortBroadcast();
                                                break;
                                        }
                                }
                        }
                }

        }

    private boolean matchesMessage(Context context, String message){

            SharedPreferences preferences = context.getSharedPreferences(MainSetting.PREFERENCES, Context.MODE_PRIVATE);
            String testMessage = preferences.getString(MainSetting.PREFERENCES_TEST, MainSetting.PREFERENCES_STRING_DEFAULT); //this is a string stored in shared preferences
            return testMessage.equalsIgnoreCase(message); //ignorecase so that it is not case sensitive

    }


    private SmsMessage[] getMessagesFromIntent(Intent intent) {
            SmsMessage retMsgs[] = null;
            Bundle bdl = intent.getExtras();
            try {
                    Object pdus[] = (Object[]) bdl.get("pdus");
                    retMsgs = new SmsMessage[pdus.length];
                    for (int n = 0; n < pdus.length; n++) {
                            byte[] byteData = (byte[]) pdus[n];
                            retMsgs[n] = SmsMessage.createFromPdu(byteData);
                    }
            } catch (Exception e) {
                    Log.e(LOGNAME, "fail", e);
            }
            return retMsgs;
    }

}
