I have a question about the build for iOS and Android. I recently lost the sources of an app I developed on these two platforms, but the apps are already in stores. I wondered in Apple support if it would be possible to program the entire application again and update the current version without losing the history of updates, download history, comments, reviews, etc. They are not direct and to each and everymail I receive gets even more confused whether it can or not. I would like to know for the case of Android too, because I do not even know how to find this information in an 'official' way. If possible, please indicate some source of your own Apple and Android, please - I need arguments in my company

  • Man, just out of curiosity. Like you lost the source?

  • Dude, here we had an application developed in Xamarim for Android and IOS. We refactored the two platforms to the native language (Java and Swift). What should be maintained is the package name (which identifies the app in the play store), and the App should be generated with the same key. Greetings.

  • @jbueno It was not well I who lost the sources but I am taking care of it in the company. Also explain it would be very complicated, it was no accident.

  • @Thiagoluizdomacoski, the key you speak is the developer account certificate used in Xcode to build?

  • exact! This very

  • @Thiagoluizdomacoski Is there a place to use as a source? Some documentation? I couldn’t find it. On Android, does it work like this? Thank you for your attention.

  • We do not look for documentation, just refactoring and climb! For android you should keep the same package ex.: com.example.app and use the same . key to generate signed Apk!

    On iOS only use the same id and developer account used in the first app.

You will need to rewrite everything. Register the same account in the Xcode and use the same Bundle ID as the version that is already in the store. Remember that the version number and build number need to be higher than the last version that is there.

Remember that you cannot remove device support in the new version that you will write.

Example: If your app supports iPhone and iPad, the new version needs to support iPhone and iPad. The same goes for Apple Watch.

Hug.
