Wykonuję mój projekt, aby zarejestrować dane z czujnika przyspieszenia i żyroskopu i zapisać go w pliku na sdcard. Ale mam problem, kiedy zaczynam nagrywać przez więcej niż 1 sekundę, wynik w pliku to tylko 1 dane, które składają się z 1 osi x, 1 y osi i 1 osi z. Idealnie rzecz biorąc, powinien dostać więcej danych w pliku, ponieważ jest nagrywanaZapisz dane czujnika do pliku w Androidzie
