Android获取设备号标识符

封装了一个工具类，直接调用getDeviceId方法就行，要注意如果targetSdkVesion高于28时，获取的deviceId带有随机性不是唯一的，所以生成的deviceId要注意保存

public class DeviceIdUtil {

    public static String getDeviceId(Context context) {
        final int targetSdkVersion = context.getApplicationInfo().targetSdkVersion;
        if (targetSdkVersion > Build.VERSION_CODES.P && Build.VERSION.SDK_INT > Build.VERSION_CODES.P) {
            return getUniqueID(context);
        } else {
            return getTelId(context);
        }
    }

    @SuppressLint("HardwareIds")
    private static String getTelId(Context context) {
        final TelephonyManager manager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
        return manager.getDeviceId();
    }

    private static String getUniqueID(Context context) {
        String id = null;
        @SuppressLint("HardwareIds") final String androidId = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ANDROID_ID);
        if (!TextUtils.isEmpty(androidId) && !"9774d56d682e549c".equals(androidId)) {
            UUID uuid = UUID.nameUUIDFromBytes(androidId.getBytes(StandardCharsets.UTF_8));
            id = uuid.toString();
        }

        if (TextUtils.isEmpty(id)) {
            id = getUUID();
        }

        return TextUtils.isEmpty(id) ? UUID.randomUUID().toString() : id;
    }

    @SuppressLint("HardwareIds")
    private static String getUUID() {
        String serial = null;

        String m_szDevIDShort = "35" +
                Build.BOARD.length() % 10 + Build.BRAND.length() % 10 +

                ((null != Build.SUPPORTED_ABIS) ? Build.SUPPORTED_ABIS.length : 0) % 10 +

                Build.DEVICE.length() % 10 + Build.DISPLAY.length() % 10 +

                Build.HOST.length() % 10 + Build.ID.length() % 10 +

                Build.MANUFACTURER.length() % 10 + Build.MODEL.length() % 10 +

                Build.PRODUCT.length() % 10 + Build.TAGS.length() % 10 +

                Build.TYPE.length() % 10 + Build.USER.length() % 10; //13 位

        if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.P) {
            try {
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                    serial = android.os.Build.getSerial();
                } else {
                    serial = Build.SERIAL;
                }
                //API>=9 使用serial号
                return new UUID(m_szDevIDShort.hashCode(), serial.hashCode()).toString();
            } catch (Exception exception) {
                serial = "serial" + UUID.randomUUID().toString(); // 随便一个初始化
            }
        } else {
            serial = android.os.Build.UNKNOWN + UUID.randomUUID().toString(); // 随便一个初始化
        }

        //使用硬件信息拼凑出来的15位号码
        return new UUID(m_szDevIDShort.hashCode(), serial.hashCode()).toString();
    }
}
