Some applications don't like user downloaded certificates, so in order to inspect web traffic for some apps we actually have to decompile the application & add a few things & recompile it.

Automatic

The tool https://github.com/shroudedcode/apk-mitm will automatically make the necessary changes to the application to start capturing the requests and will also disable certificate pinning (if any).

Manual

First we decompile the app: apktool d *file-name*.apk

Then we go into the Manifest.xml file & scroll down to the <\application android> tag & we are going to add the following line if it isn't already there:

android:networkSecurityConfig="@xml/network_security_config

Before adding:

After adding:

Now go into the res/xml folder & create/modify a file named network_security_config.xml with the following contents:

<network-security-config>  
      <base-config>  
            <trust-anchors>  
                <!-- Trust preinstalled CAs -->  
                <certificates src="system" />  
                <!-- Additionally trust user added CAs -->  
                <certificates src="user" />  
           </trust-anchors>  
      </base-config>  
 </network-security-config>

Then save the file & back out of all the directories & rebuild the apk with the following command: apktool b *folder-name/* -o *output-file.apk*

Finally, you need just to sign the new application. Read this section of the page Smali - Decompiling/[Modifying]/Compiling to learn how to sign it.
