Android – can I share the certificate used to sign APK?
Multiple Android developers in our project can access the Google play console to publish APK updates from their computers
The APK must be signed with the same certificates as the previous version
So far, I haven't seen any mention in the document or discussion
The initial version of the application was released by the first developer. Now, the second developer also wants to release some updates. However, this seems to be blocked, so only updates can be uploaded from the APK signed by the first developer's computer
resolvent:
One way to solve this problem is to use the Google play app signing function of the developer console. Your signature key can be stored with Google to assist in uploading the key for building. After uploading the build version, Google will re sign with the actual signature key. If other developers appear, you can cancel the upload key and generate a new key, But the actual signature key remains secure in Google land
