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:
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.
