套接字权限-Android清单 [英] Permission for sockets - android manifest

问题描述

我已经编写了一个简单的测试应用程序，用于使用java amqp lib（实现'com.rabbitmq：amqp-client：5.7.1'）读取RabbitMQ队列。 / p>

但是由于Android权限（套接字），我在连接到我的兔子服务器时遇到了麻烦

这是错误消息：

W / System.err：java.net.SocketException：套接字失败：EPERM（不允许操作）

我尝试不成功地将 android.permission.INTERNET 添加到清单中。看起来像这样：

 <？xml version = 1.0 encoding = utf-8？> 
<清单xmlns：android = http://schemas.android.com/apk/res/android 
 package = com.example.androidwebsocket> 
 
<使用权限android：name = android.permission.INTERNET /> 
 
<应用程序
 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 =。MainActivity> 
< intent-filter> 
< action android：name = android.intent.action.MAIN /> 
 
< category android：name = android.intent.category.LAUNCHER /> 
< / intent-filter> 
< / activity> 
< / application> 
 
< / manifest> 
  

我错过了什么？

编辑

根据请求，这是完整的错误堆栈跟踪： https://pastebin.com/WAh2B4rP

触发该错误的代码为：

  ConnectionFactory工厂= new ConnectionFactory（）; 
 factory.setUsername（ myuser）; 
 factory.setPassword（ mypass）; 
 factory.setVirtualHost（ /）; 
 factory.setHost（ myhost.io）; 
 factory.setPort（5672）; 
 
 connection = factory.newConnection（）; //错误在这里触发
 channel = connection.createChannel（）; 
  

解决方案

我丢失了

 < uses-permission android：name = android.permission.ACCESS_NETWORK_STATE /> 
  

应该提及的是，连接必须在后台线程中运行，否则其他的android将会阻止它。

也：

按照
java.net.SocketException：套接字失败：EPERM（不允许操作）

I've made a simple test application for reading RabbitMQ queues using java amqp lib (implementation 'com.rabbitmq:amqp-client:5.7.1').

But im having trouble when connectiong to my rabbit server due to Android permissions (socket)

Here is the error message:

W/System.err: java.net.SocketException: socket failed: EPERM (Operation not permitted)

I've tried, successless, to add android.permission.INTERNET to the manifest. Here is what it looks like:

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

    <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=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

What am I missing?

Edit

As requested, here is the full error stacktrace: https://pastebin.com/WAh2B4rP

And the code that triggers this error:

ConnectionFactory factory = new ConnectionFactory();
factory.setUsername("myuser");
factory.setPassword("mypass");
factory.setVirtualHost("/");
factory.setHost("myhost.io");
factory.setPort(5672);

connection = factory.newConnection(); //Error triggers here
channel = connection.createChannel();

解决方案

I was missing

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

It should mentioned that connections MUST run in Background Threads, or otherwhise android will block it.

Also:

Uninstall app from emulator as suggested in java.net.SocketException: socket failed: EPERM (Operation not permitted)
