My app is developed in react-native and the third party app provider are charging to implement the code for deep-linking.Though they have shared the .APK file with me.Through some videos & google search,I have learned that I will be able to do it by myself.I want to add deep-linking code in the AndroidManifest.xml file but how to open .apk in Android Studio and how to generate .apk file again once the changes are complete after testing on virtual device.
If you think that there will be issues by approaching through .APK file or its not the best way/standard process to achieve this ,then,please suggest me that what I need to ask them to share with me so that it can be imported in Android Studio without any issues and I can do some coding & test it.
