android获取固定uuid Android获取本机唯一序列号和可变UUID方法

UUID+设备号序列号 唯一识别码(不可变)

private String getMyUUID(){

final TelephonyManager tm = (TelephonyManager) getBaseContext().getSystemService(Context.TELEPHONY_SERVICE);

final String tmDevice, tmSerial, tmPhone, androidId;

tmDevice = "" + tm.getDeviceId();

tmSerial = "" + tm.getSimSerialNumber();

androidId = "" + android.provider.Settings.Secure.getString(getContentResolver(),android.provider.Settings.Secure.ANDROID_ID);

UUID deviceUuid = new UUID(androidId.hashCode(), ((long)tmDevice.hashCode() << 32) | tmSerial.hashCode());

String uniqueId = deviceUuid.toString();

Log.d("debug","uuid="+uniqueId);

return uniqueId;

}

java 获取可变UUID

private String getMyUUID(){

UUID uuid = UUID.randomUUID();

String uniqueId = uuid.toString();

Log.d("debug","----->UUID"+uuid);

return uniqueId;

}

获得的格式：如下样子
