Я пытаюсь выполнить приведенный ниже код на Android.
Архитектура: arm64-v8a Редакция NDK: 15.2.4203891
Я также предоставил write_external_storage разрешения.
FILE *pFile = fopen("/data/myfile.txt", "a");
fprintf(pFile, "HELLO WORLD!");
fflush(pFile);
fclose(pFile);
Это происходит сбой с этой ошибкой:
