For short arrays (a few bytes) use Integer.toHexString(data)

To view a byte array while debugging in Android Studio, create a data renderer:

HexFormat.ofDelimiter(" ").formatHex(this)

Programmatically, to send bytes as hex to a TextView:

private static final char SPACE = ' ';
private static final char[] HEX_DIGITS_UPPER = "0123456789ABCDEF".toCharArray();
public static String toHex(byte[] bytes) {
    final char[] buf = new char[3 * bytes.length];
    for (int i = 0; i < bytes.length; ++i) {
        buf[3*i] = SPACE;
        buf[3*i + 1] = HEX_DIGITS_UPPER[(bytes[i] >> 4) & 0xF];
        buf[3*i + 2] = HEX_DIGITS_UPPER[(bytes[i] & 0xF)];
    }
    return new String(buf);
}
