Android developer left Android, need to update app without original keystore - is it possible?
Our contract Android developer has provided us with the source code of the work done for us under our contract. After the completion of the contract, the developer became busy and is now unavailable. We go to another developer to support the application. However, we don't have the first developer keystore, so the app doesn't let us update it.
Do we need to support this app if we can't get the original developer? We have a lot of clients who have an application with the data they have created and need our updates.

If you have a push notification feature in your old app, you can send a push to your entire user that there is another updated version.
And just download the updated version with a different package name. And even you can send a play link in this push message. Most people use this technique and have success to move all users from the old application to the new one.
