Error in configuring network security xml in android

Question

In the android network security docs , it says to create a network_security_config.xml file in res/xml folder.

In order to make an entry in manifest file, it says to make an entry in this way

<?xml version="1.0" encoding="utf-8"?>
<manifest ... >
    <application android:networkSecurityConfig="@xml/network_security_config"
                    ... >
        ...
    </application>
</manifest>

But I am getting the error No resource identifier found for attribute 'networkSecurityConfig' in package 'android'

I also checked for the valid attributes in application tag ( android docs ), there is no attribute as "networksecurityconfig"

Answer 1

You need to set your compileSdkVersion to 24 or higher and set your buildToolsVersion to 24.0.0 or higher.

With regards to the documentation, that's a documentation bug.

Answer 2

The documentation is fixed, the xml should live inside res/xml which is not in the root but inside android/app:

android/app/src/main/res/xml/network_security_config.xml

From minimumSDK 20 you will need the file and be sure to whitelist localhost and 10.0.2.2 and 10.0.3.2 or you'll have trouble on development
