How to convert byte array to string excluding 0x00 chars in Android

Question

the result of my decryption routine returns a byte array like this:

30303030303030310000000000000000

That should be converted to (int) 00000001, but I cannot get rid of the trailing 0x00's. What would be the best way to accomplish that?

Any help would be greatly appreciated, thanks!

Answer 1

Found the workaround for trimming the trailing 0x00's in the byte array (replace or trim won't work):

public static String bytesToString(byte[] data) {
    String dataOut = "";
    for (int i = 0; i < data.length; i++) {
        if (data[i] != 0x00)
            dataOut += (char)data[i];
    }
    return dataOut;
}

Answer 2

Why not using the replace method?

String foo = new String(myBytes);
foo = foo.replace((char)0, ''); // Character with zero

Integer result = Integer.valueOf(foo);

Or even better, a Regular Expression that filters the String, getting rid of anything out of the 0-9 range.

String foo = new String(myBytes);
foo = foo.replace((char)0, ''); // Character with zero

Integer result = Integer.valueOf(foo);
