Answer 1

Yes you need to run the project once again, before making it as a signed apk change the version name and version number in build.gradle , then go to the playstore where you have published your previous signed apk, at the same place click again to upload apk and publish it. After uploading the apk it shows the update in playstore(it takes some time to show the button update).

Answer 2

您需要更新gradle中的versionCode（始终为数字，并且必须自我增加）和versionName，之后，您仅需要构建de apk。

Answer 3

Based on my experience it is good to create one key file for every application you will create and you must take care of it .

When you publish new APK file from your project you must change only version number and version name , but you must use existing key file that you created it before to sign your application's new version .
