Android: что выбрать для значений кода запроса? ⇐ JAVA

[Anonymous]

Такие методы, как ActivityCompat.requestPermissions, требуют, чтобы я передал им код запроса, который я могу позже протестировать в обратном вызове (в данном случае onRequestPermissionsResult). Есть ли какая-то передовая практика, которую я должен передать в коде запроса? Я заметил, что если я просто ввожу случайное целое число, то иногда получаю такую ​​ошибку:
