Java/Android String to Byte Conversion

Question

I have a String str = "0x01". I want to convert this string into byte exactly as it is.

I tried doing str.getBytes() and EncodingUtils.getAsciiBytes(str) but it gives byte value of each character I suppose.

I want byte variable to have value as 0x01.

Any idea how do we do it?

Thanks

Try this:

byte b = Byte.decode("0x01");

I went originally with Integer because I wasn't sure Byte.decode existed; there are/have been minor differences between the wrapper class features.

I see. Might depend on the API version.
