Programmatically update resources inside of APK

Is there a way to programmatically update the resources (more specifically icons and strings) within an APK on the device? I know I can get the APK path from an app's ApplicationInfo object. I also know that APKs are simply zip files and I can use ZipFie (https://developer.android.com/reference/java/util/zip/ZipFile) to read/modify its contents so I feel like this should be possible.

One idea I had on doing this would be to build apktool (https://ibotpeaches.github.io/Apktool/) and include this in my app. I could then decompile the resources, make my modifications, re-compile and use ZipFile to include it. This seems quite heavy though to do on an Android device. Is there any more efficient approaches?

You can use hot fix framework ,like Tencent's Tinker and Alibaba's Sophix(here is a Chinese doc)

Those hot fix framework can update your java code,so file and string drawable resource dynamically.
