SMS ContentObserver失败状态无法正常工作 - 三星

Question

我正在为SMS实施ContentObserver。 我在SMS（Android默认消息应用程序）中的任何更改时调用了onChange函数。 我已经与LeEco一起测试它工作正常，在发送，接收，失败等时触发。 但是，在三星Galaxy S6中，它不适用于失败条件。其他人，发送/接收短信工作正常。

private static final String CONTENT_SMS = "content://sms";
private static final String MSG_ID = "_id";
private static final String MSG_TYPE = "type";
private static final String MSG_ADDRESS = "address";
private static final String MSG_DATE = "date";
private static final String MSG_BODY = "body";

String lastMessageID = "";

public final Uri CONTENT_SMS_URI = Uri.parse(CONTENT_SMS);

public void onChange(boolean selfChange) {
        super.onChange(selfChange);


        Cursor cursor = context.getContentResolver().query(CONTENT_SMS_URI, null, null, null, null);

        if (null != cursor && cursor.moveToNext()){

          //  String protocol = cursor.getString(cursor.getColumnIndex("protocol"));
            int type = cursor.getInt(cursor.getColumnIndex(MSG_TYPE));

            String newMsgId = cursor.getString(cursor.getColumnIndex(MSG_ID));
            if (!lastMessageID.equals(newMsgId)){
                lastMessageID = newMsgId;

                String to = cursor.getString(cursor.getColumnIndex(MSG_ADDRESS));
                Date now = new Date(cursor.getLong(cursor.getColumnIndex(MSG_DATE)));
                String message = cursor.getString(cursor.getColumnIndex(MSG_BODY));

                if (type == Telephony.TextBasedSmsColumns.MESSAGE_TYPE_SENT){
                    // SMS sent
                    Log.e("MSG_SENT", to + " - " + now + " - " + message);

                }
                else if(type == Telephony.TextBasedSmsColumns.MESSAGE_TYPE_FAILED){
                    // Failed out going message
                    Log.e("MSG_FAILED", to + " - " + now + " - " + message);
                }
            }
        }
    }
