安卓手机本身的工具类（部分方法不断更新）

通过网络接口取MAC地址

    /**
     * 通过网络接口取
     * @return
     */
    public static String getNewMac() {
        try {
            List<NetworkInterface> all = Collections.list(NetworkInterface.getNetworkInterfaces());
            for (NetworkInterface nif : all) {
                if (!nif.getName().equalsIgnoreCase("wlan0")) continue;
                byte[] macBytes = nif.getHardwareAddress();
                if (macBytes == null) {
                    return null;
                }

                StringBuilder res1 = new StringBuilder();
                for (byte b : macBytes) {
                    res1.append(String.format("%02X:", b));
                }

                if (res1.length() > 0) {
                    res1.deleteCharAt(res1.length() - 1);
                }
                return res1.toString();
            }
        } catch (Exception ex) {
            ex.printStackTrace();
        }
        return null;
    }

跳转到应用详情界面

 /**
     * 跳转到应用详情界面
     */
    public static void gotoAppDetailIntent(Activity activity) {
        Intent intent = new Intent();
        intent.setAction(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
        intent.setData(Uri.parse("package:" + activity.getPackageName()));
        activity.startActivity(intent);
    }

获取32位uuid

   /**
     * 32位默认长度的uuid
     * (获取32位uuid)
     *
     * @return
     */
    public static String getUUID() {
        return UUID.randomUUID().toString().replaceAll("-", "");
    }

获取指定长度uuid

/**
     * (获取指定长度uuid)
     *
     * @return
     */
    public static String getUUID(int len) {
        if (0 >= len) {
            return null;
        }
        String uuid = getUUID();
        StringBuffer str = new StringBuffer();
        for (int i = 0; i < len; i++) {
            str.append(uuid.charAt(i));
        }
        return str.toString();
    }

是否使用模拟器

这里用的是第三方的库，需要添加依赖：

 implementation 'com.scottyab:rootbeer-lib:0.0.8'

public static boolean isSystemRoot(Context activity) {
        boolean isRoot = false;
        RootBeer rootBeer = new RootBeer(activity);
        if (rootBeer.isRooted()) {
            isRoot = true;
        } else {
            isRoot = false;
        }

        return isRoot;
    }

获取IMEI

   /**
     * 获取IMEI  
     * @return
     */
    public static String getPhoneIMEI(Context context) {
        TelephonyManager manager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        try {
            Method method = manager.getClass().getMethod("getImei", int.class);
            String imei1 = (String) method.invoke(manager, 0);
            String imei2 = (String) method.invoke(manager, 1);
            return imei1;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return "";
    }
