Android Question Read file to binary

[stephankuba]

Hi,

is it possible to read any file into binary? (Bits)
Because I want to change some bits and write it back to the file.
I saw the RandomAccessFile but there is only read byte.

Maybe someone has a code for this, because I don't realy understand the RandomAccessFile Library.

thank you.

Yes.

With RandomAccessFile you do not need to read the full file. You can read the required section, modify it and write it back.

You should use raf.ReadBytes and raf.WriteBytes.

thank you for your fast answear.

I have some questin about this:

Dim test As RandomAccessFile
Dim readf() As Byte

test.Initialize(File.DirRootExternal,"test.dat",False)
test.ReadBytes(readf(),????,???,???)

Msgbox(test,"test")

I want to get the hole file in the readf() array, what parameter must I choose?

thank you
