Запросить входящие SMS всегда возвращать нулевое значение в Realme

Question

Я написал код для получения SMS с номера android. Используйте content://sms/inbox, но всегда возвращает null.

main

public void getAllSmsFromProvider() {
    ContentResolver contentResolver = getContentResolver();
    Cursor smsInboxCursor = contentResolver.query(Uri.parse("content://sms/inbox"), null, null, null, null);

    if (!smsInboxCursor.moveToFirst()) return; // smsInboxCursor always return null

    // loop through the messages in inbox
    do {
        // get the value based on the index of the column
        String address = smsInboxCursor.getString(smsInboxCursor.getColumnIndex("body"));
        String body = smsInboxCursor.getString(smsInboxCursor.getColumnIndex("address"));
        long date = smsInboxCursor.getLong(smsInboxCursor.getColumnIndex("date"));

        Log.d(TAG, "getAllSmsFromProvider: " + address + " - " + date + " - " + body);

    } while (smsInboxCursor.moveToNext());

    smsInboxCursor.close();
}

манифесты

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

У меня есть проверил разрешения перед использованием этого кода. Но smsInboxCursor всегда возвращает null.

разрешения

private void checkPermissionSMS() {
    if (ContextCompat.checkSelfPermission(this, Manifest.permission.RECEIVE_SMS) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_SMS}, MY_PERMISSIONS_READ_SMS);
    } else {
        getAllSmsFromProvider();
    }
}

ошибка

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.trantien.xxx/com.trantien.xxx.view.MainActivity}: java.lang.NullPointerException: Attempt to invoke interface method 'boolean android.database.Cursor.moveToFirst()' on a null object reference

редактировать: я проверил свой код, и он имеет ошибки при работе на Realme. Но когда я попробовал на другом устройстве, все заработало. Я не понимаю: ((

Пожалуйста, проверьте следующие классы для получения SMS:

SmsFromDevice smsFromDevice = new SmsFromDevice(mContext, SmsDetailsActivity.this);
ArrayList<SmsRetriveModel> smsRetrieveModels = smsFromDevice.getSMSofNumber(numberToGetSms, "All", "1469385000000");
Log.d(TAG,smsRetrieveModels.size());

Вы можете изменить "1469385000000" lastSyncDate.

SmsFromDevice. java

    private static final String TAG = SmsFromDevice.class.getSimpleName();

    SmsFromDevice(Context context, Activity activity) {
        this.mContext = context;
        this.mActivity = activity;
    }

    //type: Inbox|All  //no:(eg:9898989898) //lastSyncDate in milliseconds
    ArrayList<SmsRetriveModel> getSMSofNumber(String no, String type, String lastSyncDate) {
        numberToGetSms = no;
        if (checkSMSPermission()) {
            final ContentResolver contentResolver = mContext.getContentResolver();

            Uri myMessage = null;
