我想读取连接到安卓平板电脑的 USB 闪存的第一个扇区或第一个字节！
我知道应该使用 RandomAccessFile，但我不知道我的 USB 闪存的地址是什么！
感谢您的帮助
我找到了这段代码，但我不知道应该放什么来代替 args[0]
public class FAT16
{
public static void main(String[] args) throws IOException
{
// open file whose name is on the command line for input
RandomAccessFile file = new RandomAccessFile(args[0], "r");
// skip ahead to byte 19 (0x13 hex) where the num of sectors is stored
file.seek(0x13);
// 2-byte values are little-endian; Java is big-endian, so we
// have to read the two bytes separately and glue them together
// ourselves
int low = file.readUnsignedByte();
int high = file.readUnsignedByte();
int sectorsOnDisk = low + (high * 256);
// skip ahead to where the sectors per FAT is stored
file.seek(0x16);
low = file.readUnsignedByte();
high = file.readUnsignedByte();
int sectorsPerFAT = low + high * 256;
// skip back to where the bytes per sector is stored
file.seek(0x0b);
low = file.readUnsignedByte();
high = file.readUnsignedByte();
int bytesPerSector = low + high * 256;
// report size of disk and number of sectors per FAT
System.out.println("Disk size = " + sectorsOnDisk * bytesPerSector );
System.out.println("Sectors per FAT = " + sectorsPerFAT);
}
}
我知道我们应该在 linux 中使用“/dev/sdaX”，但是对于 adnroid 会是什么？
