Прочтите sqlite из папки с ошибкой папки

Моя база данных.

public class DatabaseHelper extends SQLiteOpenHelper { public static final String DBNAME = "db3000.sqlite"; public static final String DBLOCATION = "/data/data/com.gnirt69.sqlitefromassetexample/databases/"; private Context mContext; private SQLiteDatabase mDatabase; public DatabaseHelper(Context context) { super(context, DBNAME, null, 1); this.mContext = context; } @Override public void onCreate(SQLiteDatabase db) { } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { } public void openDatabase() { String dbPath = mContext.getDatabasePath(DBNAME).getPath(); if(mDatabase != null && mDatabase.isOpen()) { return; } mDatabase = SQLiteDatabase.openDatabase(dbPath, null, SQLiteDatabase.OPEN_READWRITE); } public void closeDatabase() { if(mDatabase!=null) { mDatabase.close(); } } public ArrayList<word> getListWord() { word product = null; ArrayList<word> productList = new ArrayList<>(); openDatabase(); Cursor cursor = mDatabase.rawQuery("SELECT * FROM word", null); cursor.moveToFirst(); while (!cursor.isAfterLast()) { product = new word(cursor.getInt(0), cursor.getString(1), cursor.getString(2), cursor.getString(3),cursor.getString(4),cursor.getInt(5)); productList.add(product); cursor.moveToNext(); } cursor.close(); closeDatabase(); return productList; } } 

Мой framgnet.class

  @Override public void onViewCreated(View view, Bundle savedInstanceState) { super.onViewCreated(view, savedInstanceState); mDBHelper = new DatabaseHelper(getActivity()); //Check exists database File database = getActivity().getDatabasePath(DatabaseHelper.DBNAME); if(false == database.exists()) { mDBHelper.getReadableDatabase(); //Copy db if(copyDatabase(getActivity())) { Toast.makeText(getActivity(), "Copy database succes", Toast.LENGTH_SHORT).show(); } else { Toast.makeText(getActivity(), "Copy data error", Toast.LENGTH_SHORT).show(); return; } } // Get product list in db when db exists mProductList = mDBHelper.getListWord(); // getCategoryFromDataBase(); } private boolean copyDatabase(Context context) { try { InputStream inputStream = context.getAssets().open(DatabaseHelper.DBNAME); String outFileName = DatabaseHelper.DBLOCATION + DatabaseHelper.DBNAME; OutputStream outputStream = new FileOutputStream(outFileName); byte[]buff = new byte[1024]; int length = 0; while ((length = inputStream.read(buff)) > 0) { outputStream.write(buff, 0, length); } outputStream.flush(); outputStream.close(); Log.w("MainActivity","DB copied"); return true; }catch (Exception e) { e.printStackTrace(); return false; } } 

Сначала я попытался вызвать данные чтения в Activity.class; Он работал отлично, но когда я пытаюсь его в Фрагменте, он не запускается и показывается

 java.io.FileNotFoundException: /data/data/com.gnirt69.sqlitefromassetexample/databases/db3000.sqlite: open failed: EACCES (Permission denied) 

Что здесь происходит?
Пожалуйста, помогите мне.
