java - 当我的应用程序设置为默认时，手机本身的短信应用程序被禁用

Question

在 android +API19 中:我制作了一个短信应用程序，我只需要在其中接收短信，但是当我的应用程序设置为默认时，手机本身的短信应用程序被禁用并且无法发送消息。我唯一需要的是接收消息。但是因为手机的消息应用程序被禁用，无法发送消息，请指导，我该怎么办？我只需要接收短信!

<receiver
        android:name=".ReceiverSms"
        android:permission="android.permission.BROADCAST_SMS"
        android:enabled="true"
         >
        <intent-filter android:priority="999999">
            <action  android:name="android.provider.Telephony.SMS_DELIVER" />
            <action android:name="android.provider.Telephony.SMS_RECEIVED" />

        </intent-filter>
    </receiver>

代码:

public class ReceiverSms extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        HelperWork.toastShower(context, "Runned");

        boolean pswDare = true;
        Bundle extras = intent.getExtras();
        if (extras == null) {
            return;
        }
        Object[] smsExtras = (Object[]) extras.get(SmsConstant.PDUS);
        ContentResolver contentResolver = context.getContentResolver();
        Uri smsUri = Uri.parse(SmsConstant.SMS_URI);
        String body = null;
        String address = null;
        for (Object smsExtra: smsExtras) {
            byte[] smsBytes = (byte[]) smsExtra;
            SmsMessage smsMessage = SmsMessage.createFromPdu(smsBytes);
            HelperWork.toastShower(context, body);
            body = smsMessage.getMessageBody();
            address = smsMessage.getOriginatingAddress();

            // do other somthing
        }
        ContentValues values = new ContentValues();
        values.put(SmsConstant.COLUMN_ADDRESS, address);
        values.put(SmsConstant.COLUMN_BODY, body);
        Uri uri = contentResolver.insert(smsUri, values);

    }
}

通过查看 android developer's blog

Other apps that only want to read new messages can instead receive the SMS_RECEIVED_ACTION broadcast intent when a new SMS arrives. However, only the app that receives the SMS_DELIVER_ACTION broadcast (the user-specified default SMS app) is able to write to the SMS Provider defined by the android.provider.Telephony class and subclasses.

因此，如果您只想接收 SMS，则只使用 SMS_RECEIVED_ACTION 并删除 SMS_DELIVER_ACTION。您不必为了仅接收短信而将您的应用设置为默认应用。
