How to run apk file sources in android studio?

Question

Java

I have a working apk file. I unpacked it to the source. How can I properly import them into Android Studio so that I can run the project and debug the application?
I created an empty android application. In the /app/src/main/ folder, I threw all the apk sources. as the source codes were sorted out, so I copied them, did not change anything.
At first, Android Studio complained that they couldn't serge Manifests. Swearing at several lines like:

<uses-feature android:glEsVersion="20000" android:required="true" />

I removed them.
This is what came out.

What am I doing wrong?

Answer 1

What am I doing wrong?

You are engaged in reverse engineering, which is many times more labor-intensive than writing such software by the direct method.

Answer 2

Decompiling to understand how the application works, not to run it.
