Translated from 日本語 • View original I don't know how to upload the extension file.
See the Devleloper Console Help
Note: Currently, due to the limitations of the new Google Play Developer Console, it is not possible to add an extension file to the first APK file where you upload a new app. To avoid this issue, start by uploading only the APK file and replacing it with an APK file with an extension file added if necessary. These actions can also be performed on the draft APK, so it won't affect existing or potential users. _
Apparently you can see that you can't add extension files. But I don't know how to avoid it.
**"Please replace it with an APK file with an enhanced file added"? **
Then, the APK and the extension file are integrated!
When I tried my best to find out,
is a hit.
it's a dummy apk. When you first upload your apk you will not have any option for the expansion files. From second apk onwards you will have that option. It looks weird
If you upload the same APK file twice, you will have the option to upload the extension file the second time.
(The first time it doesn't come out)
**What is it! **
