从 Android 应用程序访问 Internet 需要什么权限？

Question

I get the following Exception running my app:

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

How do I solve the missing permission problem?

Answer 1

Add the INTERNET permission to your manifest file.

You have to add this line:

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

outside the application tag in your AndroidManifest.xml

Answer 2

In the latest release of Google Play, Google removed the need to ask permission for internet as "most apps need it anyways nowadays". However, for users who have older versions, it is still recommended to leave the code below in your manifest

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

Answer 3

just put above line like below

<?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>

Answer 4

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

Answer 5

If you want using Internet in your app as well as check the network state ie 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>

Answer 6

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.

Answer 7

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" />

Answer 8

I had the same problem even use <uses-permission android:name="android.permission.INTERNET" />

If you want connect web api using http not https . Maybe you use android device using Android 9 (Pie) or API level 28 or higher . android:usesCleartextTraffic default value is false . You have to set be

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
    <uses-permission android:name="android.permission.INTERNET" />
    <application
        ...
        android:usesCleartextTraffic="true" <!-- this line -->
        ...>
           ...
    </application>
</manifest>

Finally, should be https

https://developer.android.com/guide/topics/manifest/application-element#usesCleartextTraffic

Answer 9

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);
    }

Answer 10

Just Add these 2 permissions

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

in your app's AndroidManifest.xml

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.example.android.networkusage"
        ...>
    
    
        <uses-permission android:name="android.permission.INTERNET" />
        <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    
        <application 
            ...>
            ...
        </application>
    </manifest>

Happy Coding:)
