Question

我在某些设备上遇到问题，例如某些android盒子或华为手机如果用户使用数据包监视器应用程序，那么我需要保护我的应用程序，如果用户在设备上启用了vpn而不请求jsonparse，我要做的就是但是即使vpn处于非活动状态，有些设备也无法运行jsonparse。

这是我的代码

public static boolean isVpnConnectionActive() {
        List<String> networks = new ArrayList<>();

        try {
            for (NetworkInterface networkInterface : Collections.list(NetworkInterface.getNetworkInterfaces())) {
                if (networkInterface.isUp()) {
                    networks.add(networkInterface.getName());
                }if (networkInterface.getName().contains("tun0")||  networkInterface.getName().contains("ppp0")) {
                    System.exit(1);
                }

            }
        } catch (Exception ignored) {

        }
        return networks.contains("tun0");


    }

我在启动和创建时请求jsonParse，以避免用户启动我的应用程序后激活VPN

 @Override
    protected void onStart() {
        super.onStart();
        if (isVpnConnectionActive()) {



        }else { jsonParse();}}

我以此方式请求json解析

    private void jsonParse() {

        final String url = "http://example.dns.net/json.php";

        JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null,
                new Response.Listener<JSONObject>() {
                    @Override
                    public void onResponse(JSONObject response) {
                        try {
                            JSONArray jsonArray = response.getJSONArray("employees");

                            for (int i = 0; i < jsonArray.length(); i++) {
                                JSONObject employee = jsonArray.getJSONObject(i);

                                String Urlx = employee.getString("urlx");
                                String Urlc = employee.getString("urlc");
                                String Urlb = employee.getString("urlb");
                                String TextBar = employee.getString("TextBar");


    DFG_1 = Urlx;
    DFG_2 = Urlc;
    DFG_3 = Urlb;
    Text_Bar = TextBar;
    text2.setText(TextBar);


}


                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                error.printStackTrace();
            }


        });
        mQueue.add(request);

    }

为什么android pie和某些设备无法通过这种方式工作？

您是否有理由不使用<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="hibernate.connection.driver_class">org.postgresql.Driver</property> <property name="hibernate.connection.url">jdbc:postgresql://localhost:5433/logistica</property> <property name="hibernate.connection.username">testUser</property> <property name="hibernate.connection.password">pass</property> <property name="hibernate.show_sql">true</property> <property name="hibernate.dialect">org.hibernate.dialect.PostgreSQL9Dialect</property> <mapping class="com.log.iei.logistica.data.entities.ClientEntity" /> <mapping class="com.log.iei.logistica.data.entities.ContractEntity" /> <mapping class="com.log.iei.logistica.data.entities.ContainerEntity" /> <mapping class="com.log.iei.logistica.data.entities.VehicleEntity" /> <mapping class="com.log.iei.logistica.data.entities.TransactionEntity" /> </session-factory> </hibernate-configuration>，请参阅https://developer.android.com/reference/android/net/NetworkCapabilities#hasTransport(int)？
