Android 애플리케이션에서 인터넷에 액세스하려면 어떤 권한이 필요합니까?

Android 애플리케이션에서 인터넷에 액세스하려면 어떤 권한이 필요합니까?

---

내 앱을 실행하면 다음과 같은 예외가 발생합니다.

java.net.SocketException: Permission denied (maybe missing INTERNET permission)

누락 된 권한 문제는 어떻게 해결합니까?

---

업데이트 :
Google은 최신 버전의 Google Play에 대한 인터넷 권한을 요청할 필요가 없습니다.

매니페스트 파일에 [INTERNET] [1] 권한을 추가합니다.

다음 줄을 추가해야합니다.

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

AndroidManifest.xml의 애플리케이션 태그 외부

Google Play의 최신 릴리스에서 Google은 "요즘 대부분의 앱에 인터넷 권한이 필요하기 때문에"인터넷에 대한 권한을 요청할 필요가 없습니다. 그러나 이전 버전을 사용하는 사용자의 경우 매니페스트에 아래 코드를 남겨 두는 것이 좋습니다.

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

아래와 같이 선 위에 올려주세요

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.avocats.activeavocats"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="9"
    android:targetSdkVersion="16" />

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

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >


    <activity
        android:name="com.example.exp.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

---

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

---

If you want using Internet in your app as well as check the network state i.e. Is app is connected to the internet then you have to use below code outside of the application tag.

For Internet Permission:

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

For Access network state:

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

Complete Code:

<uses-sdk
    android:minSdkVersion="9"
    android:targetSdkVersion="16" />

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

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >


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

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

---

if just using internet then use-

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

if you are getting the state of internet then use also -

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

just above the application tag.

---

forget about adding the permission into the manifest Add this code as a method

public static boolean hasPermissions(Context context, String... permissions)
{
    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null)
    {
        for (String permission : permissions)
        {
            if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED)
            {
                return false;
            }
        }
    }
    return true;
}

and write this in your Main

int PERMISSION_ALL = 1;
    String[] PERMISSIONS = {Manifest.permission.READ_CONTACTS, Manifest.permission.WRITE_CONTACTS, Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_SMS, Manifest.permission.CAMERA};

    if (!hasPermissions(this, PERMISSIONS)) {
        ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
    }

Just put below code in AndroidManifest :

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

---

As per current versions, Android doesn't ask for permission to interact with the internet but you can add the below code which will help for users using older versions Just add these in AndroidManifest

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

---

Use these:

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

---

To request for internet permission in your code you must add these to your AndroidManifest.xml file

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

Google removed the need to ask permission for the internet for the latest version. Still, to request for internet permission in your code you must add these to your AndroidManifest.xml file.

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