android - 无法通过此代码接收消息(广播接收器)

Question

我没有通过我的应用程序收到消息 - 帮助我，我不知道我必须在此代码中进行哪些更改，请告诉我我应该将其设置为默认值(这样它会给我一条消息)还是在我的代码 - 我确实收到了一条消息，但不是来自这个应用程序

    public class IncomingSms extends BroadcastReceiver {

    final SmsManager sms = SmsManager.getDefault();

    public void onReceive(Context context, Intent intent) {

        // Retrieves a map of extended data from the intent.
        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;
                    String message = currentMessage.getDisplayMessageBody();

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

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

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

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

        }
    }

}

我认为，你应该添加这段代码

<receiver android:name=".yourService" android:exported="true" > 
  <intent-filter> 
    <action android:name="android.provider.Telephony.SMS_RECEIVED" />
  </intent-filter> 
</receiver>

在 list 中的应用程序标签中

或

或者您必须在 Activity 类中注册您的 InComingservice。

例如

private InComingSMSReceiver inComingSMSReceiver = new InComingSMSReceiver();
@Override
   protected void onResume() {
      super.onResume();
      registerReceiver(inComingSMSReceiver, new IntentFilter("android.provider.Telephony.SMS_RECEIVED"));
   }

   @Override
   protected void onPause() {
      super.onPause();
      unregisterReceiver(inComingSMSReceiver);
   }
