Extracted apk file from apk extractor app not working

[onos1]

Expected behavior

After extracting the apk file, I expected when the raw the file is clicked it should show the app asking if I want to install it as an update or asking permission to install

Actual behavior

The extracted apk is showing file format not supported when clicked

How to reproduce

• download the app here
• click on any app to extract their apk file
• go-to the file location of the extracted apk file mostly in downloads
• click on the extracted apk file
  File format not supported!

• Mobile: Infinix note 4
• Operating system: android 7.0
• version: 1.4

That's an issue of your file manager, not of apkExtractor. Try "Amaze" from F-Droid instead of your file manager.

Other apk extractors work fine on my file manager, why should I need extra file manager?

Because it works in all other file managers. Yours is trying to open it as an archive.

iam another user whom trying to find answer on the subject and i did follow what you wrote earlier on using other file manager.
i tried "amaze" and yet got the same result.
the thing is that, the apk installing on both file managers but when opened it fails to work and i'am being directed to the app store to download the app from there.
its stating that there are missing components and therefor must be reinstalled via the app store.
in my case i was using apk extractor app which probably couldnt extract all of the files needed to make it work.
i will try and look for the original apk if still on my mobile somewhere and try to back it up.
have a great day all.

No, the apk file is copied unmodified from the OS private location, as you can see in the source for extractWithRoot() and extractWithoutRoot(). The mentioned applicationInfo.sourceDir is the file path to the OS private copy (see documentation) and dst is the destination directory in the external storage.

In fact, if you rebuild an apk from pieces, Android will refuse to install your apk over a previous version, because you do not have the apk author's private cryptographic key (required to sign the apk) an Android will notice the signing key mismatch. So this is not an option for an apk extractor app.
