I want to serialize number to byte array on Android, send bytes by
UDP, and deserialize number from bytes on the desctop jvm
It is work fine on Emulator SDK 2.0. And it is does not work on
Emulator SDK 1.5 (and on HTC Hero)
I use the following functions for serialization. Does anybody know the
reason?
public static byte[] intToByteArray(Integer value) {
if (value == null) {
return new byte[]{(byte) 0xFFFF, (byte) 0xFFFF, (byte)
0xFFFF, (byte) 0xFFFF};
}
return new byte[]{
(byte) ((int) value >>> 24),
(byte) ((int) value >>> 16),
(byte) ((int) value >>> 8),
(byte) (int) value};
}
public static Integer byteArrayToInt(byte[] b) {
return (b[0] << 24)
+ ((b[1] & 0xFF) << 16)
+ ((b[2] & 0xFF) << 8)
+ (b[3] & 0xFF);
}
public static byte[] shortToByteArray(Short value) {
if (value == null) {
return new byte[]{(byte) 0xFFFF, (byte) 0xFFFF};
}
return new byte[]{(byte) ((value & 0xFF00) >> 8), (byte)
(value & 0x00FF)};
}
public static Short byteArrayToShort(byte[] b) {
return (short) (((b[0] << 8)) | ((b[1] & 0xff)));
}
