Android改型仅在使用emulator时连接

我的计算机中有一个本地服务器，我想使用改造发出请求，如果我使用android emulator没有问题，我发出请求没有问题，但是当我尝试在我的android设备中使用它时（并将ip更改为键入ipconfig时显示的ip）

舱单：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="escoladeltreball.org.decaught">

    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity
            android:name=".TutorialActivity"
            android:screenOrientation="portrait">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".LoginActivity" />
        <activity android:name=".RegisterActivity" />
        <activity android:name=".RolSelection"></activity>
    </application>

</manifest>

将客户端改为：

public class RetrofitClient {

    private static Retrofit retrofit = null;

    public static Retrofit getClient(String baseUrl) {

        OkHttpClient.Builder clientBuilder = new OkHttpClient.Builder();



        if (retrofit==null) {


            retrofit = new Retrofit.Builder()
            .baseUrl(baseUrl)
            .client(clientBuilder.build())
            .addConverterFactory(GsonConverterFactory.create())
            .build();
        }
        return retrofit;
    }
}

最后，按如下方式调用函数

private void signIn() {
    boolean isValid = validate();
    if (isValid) {

        mService.get_tokken(user.getText().toString(), password.getText().toString()).enqueue(new Callback<Tokken>() {
            @Override
            public void onResponse(Call<Tokken> call, Response<Tokken> response) {
                if (response.isSuccessful()) {

                    System.out.println("Te lo imprimo");
                    System.out.println(response.body().toString());
                    Toast.makeText(LoginActivity.this, "tokken recibido", Toast.LENGTH_SHORT).show();
                } else {
                    int statusCode = response.code();
                    // handle request errors depending on status code
                }
            }

            @Override
            public void onFailure(Call<Tokken> call, Throwable t) {
                Toast.makeText(LoginActivity.this, "Error al recibir tokken", Toast.LENGTH_SHORT).show();

                t.printStackTrace();
                Log.d("MainActivity", "error loading from API");

            }
        });

    }
}

问题不在于安卓或改造，而在于服务器，服务器不允许外部连接

@伍吉努吉是对的

这里没有太多问题，但我的假设是，您计算机上的本地服务器仅对您的计算机可用，并且不会暴露在任何地方……甚至对本地网络也是如此。我会尝试搜索您正在使用的任何服务器工具的配置，并找出如何根据您想要完成的任务对其进行配置，或者开始在web环境中运行服务器。这绝对不是改装/Android问题。您的设备和服务器必须在同一网络中谢谢，问题出在服务器上！

public class RetrofitClient {

    private static Retrofit retrofit = null;

    public static Retrofit getClient(String baseUrl) {

        OkHttpClient.Builder clientBuilder = new OkHttpClient.Builder();



        if (retrofit==null) {


            retrofit = new Retrofit.Builder()
            .baseUrl(baseUrl)
            .client(clientBuilder.build())
            .addConverterFactory(GsonConverterFactory.create())
            .build();
        }
        return retrofit;
    }
}

private void signIn() {
    boolean isValid = validate();
    if (isValid) {

        mService.get_tokken(user.getText().toString(), password.getText().toString()).enqueue(new Callback<Tokken>() {
            @Override
            public void onResponse(Call<Tokken> call, Response<Tokken> response) {
                if (response.isSuccessful()) {

                    System.out.println("Te lo imprimo");
                    System.out.println(response.body().toString());
                    Toast.makeText(LoginActivity.this, "tokken recibido", Toast.LENGTH_SHORT).show();
                } else {
                    int statusCode = response.code();
                    // handle request errors depending on status code
                }
            }

            @Override
            public void onFailure(Call<Tokken> call, Throwable t) {
                Toast.makeText(LoginActivity.this, "Error al recibir tokken", Toast.LENGTH_SHORT).show();

                t.printStackTrace();
                Log.d("MainActivity", "error loading from API");

            }
        });

    }
}
