    System.out.println(new UUID(123456789L, 123456789L));
}

From source file:Main.java

public static UUID emptyGuid() {
    return new UUID(0, 0);
}

From source file:Main.java

public static boolean isGuidEmpty(UUID value) {
    return (new UUID(0L, 0L).equals(value));
}

From source file:Main.java

public static UUID toUUID(byte[] bytes) {
    ByteBuffer bb = ByteBuffer.wrap(bytes);
    long firstLong = bb.getLong();
    long secondLong = bb.getLong();
    return new UUID(firstLong, secondLong);
}

From source file:Main.java

public static UUID getUuidFromByteArrayBigEndian(byte[] bytes) {
    ByteBuffer bb = ByteBuffer.wrap(bytes);
    long high = bb.getLong();
    long low = bb.getLong();
    UUID uuid = new UUID(high, low);
    return uuid;//from w  ww . ja v  a2 s  . c  om
}

From source file:Main.java

public static UUID getUUID(Context context) {
    TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    String uniqueId = tm.getDeviceId();
    UUID deviceUuid = new UUID(uniqueId.hashCode(), 64);
    return deviceUuid;
}

From source file:Main.java

public static UUID toUuid(long assignedNumber) {
    return new UUID((assignedNumber << 32) | 0x1000, leastSigBits);
}

From source file:Main.java

}

From source file:Main.java

    long lsb = bb.getLong();
    long msb = bb.getLong();
    UUID uuid = new UUID(msb, lsb);
    return uuidToString(uuid);
}

From source file:Main.java
