Generating APK with support for proxying into network traffic

The AppLovin team may request a debuggable APK that can proxy into networking traffic by using Android’s Network Security Configuration feature.

These instructions show you how to create such an APK:

1. If you have not already done so, create a new XML file: res/xml/network_security_config.xml.
2. In your application manifest AndroidManifest.xml, add the configuration to your application attribute:

   <manifest>
     <application android:networkSecurityConfig="@xml/network_security_config">
       ⋮
     </application>
   </manifest>

3. In the res/xml/network_security_config.xml file, add the following:

   <network-security-config>
     <debug-overrides>
       <trust-anchors>
         <certificates src="system" />
         <certificates src="user" />
       </trust-anchors>
     </debug-overrides>
   </network-security-config>

4. Create a debug build.
   • Build with a debug configuration.

Unity

Unity deprecated the use of res folders in the Assets/Plugins/Android directory. These instructions show you how to create a debuggable APK with proxy support when you use Unity to develop your application:

1. Create an Android Library by creating a new folder Assets/Plugins/Android/«name-of-your-library».androidlib.
2. Create an AndroidManifest.xml file in Assets/Plugins/Android/«name-of-your-library».androidlib/, and add the following to that file:

   <?xml version="1.0" encoding="utf-8"?>
   <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.android.library.network.security">
     <application android:networkSecurityConfig="@xml/network_security_config" />
   </manifest>

3. Create a new project.properties file in Assets/Plugins/Android/«name-of-your-library».androidlib/ with the following contents:

   target=android-31
   android.library=true
   

4. If you have not already done so, create a new XML file, network_security_config.xml, with the following contents:

   <network-security-config>
     <debug-overrides>
       <trust-anchors>
         <certificates src="system" />
         <certificates src="user" />
       </trust-anchors>
     </debug-overrides>
   </network-security-config>

5. Move your network_security_config.xml file into the Assets/Plugins/Android/«name-of-your-library».androidlib/res/xml folder.
6. Create a debug build.
   • Select Development Build in Build Settings.
