Android Studio 中 OTP 应用程序的 java.net.SocketException:socketfailed:EACCES(permission denied)

Question

我正在尝试创建一次性密码访问 android 应用程序。我已经使用 wamp 创建了一个本地主机服务器，并且我正在尝试使用我设计的移动应用程序访问那个东西。不幸的是，我在日志猫中收到如下错误：

03-07 10:42:35.097 31217-31217/com.example.user.myapplication V/ActivityThread: updateVisibility : ActivityRecord{1ecab2fb token=android.os.BinderProxy@23c38b5b {com.example.user.myapplication/com.example.user.myapplication.activity.SmsActivity}} show : true

03-07 10:42:37.617 31217-31217/com.example.user.myapplication D/SRIB_DCS: log_dcs ThreadedRenderer::initialize entered! 

我已包含所有权限，这是我的 AndroidManifest.xml 文件

<?xml version="1.0" encoding="utf-8"?>

<application
    android:name=".app.MyApplication"
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:supportsRtl="true"
    android:theme="@style/MyMaterialTheme">

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.RECEIVE_SMS" />
    <uses-permission android:name="android.permission.READ_SMS" />

    <activity
        android:name=".activity.SmsActivity"
        android:label="@string/title_activity_sms">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <activity
        android:name=".activity.MainActivity"
        android:label="@string/app_name"
        android:windowSoftInputMode="adjustResize">

    </activity>

    <!-- SMS Receiver -->
    <receiver android:name=".receiver.SmsReceiver">
        <intent-filter android:priority="99999">
            <action android:name="android.provider.Telephony.SMS_RECEIVED" />
        </intent-filter>
    </receiver>


    <!-- Intent service -->
    <service
        android:name=".service.HttpService"
        android:exported="false" />

</application>

我现在有点困惑，我知道我被一些愚蠢的东西困住了。如果有人能帮助我解决这个问题，我将不胜感激。

如果您的目标是 API 23+ (Marshmallow)，则在需要权限时会发出权限请求，否则可能会导致不受欢迎的用户体验。
