我自己以前用的一个工具类,用到了uuid,给你一用吧
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.RandomAccessFile;
import java.util.UUID;

import android.content.Context;

public class Installation {
private static String sID = null;
private static final String INSTALLATION = "INSTALLATION";

public synchronized static String id(Context context) {
if (sID == null) {
File installation = new File(context.getFilesDir(), INSTALLATION);
try {
if (!installation.exists())
writeInstallationFile(installation);
sID = readInstallationFile(installation);
} catch (Exception e) {
throw new RuntimeException(e);
}
}
return sID;
}

private static String readInstallationFile(File installation)
throws IOException {
RandomAccessFile f = new RandomAccessFile(installation, "r");
byte[] bytes = new byte[(int) f.length()];
f.readFully(bytes);
f.close();
return new String(bytes);
}

private static void writeInstallationFile(File installation)
throws IOException {
FileOutputStream out = new FileOutputStream(installation);
String id = UUID.randomUUID().toString();
out.write(id.getBytes());
out.close();
}
}

// 调用方法
// 获取标识
String SerialNumber = "";
SerialNumber = Installation.id(mContext); // 静态方法,直接调用
