I extracted an APK for the Pocket app using adb pull, and decompiled it with apktool. I then tried importing it onto Android Studio (on Windows) and selected to import with Android Gradle instead of just Gradle (since the later doesn't work for me). I did some looking up online and it seems that apktool isn't perfect for decompiling apps, and I might be doing something wrong with showing the preview, what I tried is opening up XML files in the layout folder and the preview would not load (after looking stuff up online, apparently somewhere on the bottom of Android Studio, I have to select text instead of design but I don't see it anywhere). Are there ways to decompile the APKs like for the pocket app better, as well actually be able to preview XML files?
I attached the pocket APK in case that's helpful.
