Extract apk with winrar. After use https://github.com/talshimoni/mono_unbundle tool for extract dll from lib\arm64-v8a\libmonodroid_bundle_app.so and open XamaText.dll with dnspy

Am i right?

[BlackHat]

YES ! But it would be better if you can tell the way to patch the APK. 
For example, I changed the details in the DLL mentioned by you. So How can I save the change ?

How can I recompile it after doing changes in DLL ?
