Building and submitting an update to your app is much easier than creating it for the first time. The following is a step-by-step guide to the process.
How to Update Your Android App in the Google Play Store
1. Log into your mag+ Publish account and click on the "Apps" tab.
2. Change your Build Settings or other options as needed.
Each section of the Assets and Configuration area features a label indicating whether all the required information has been completed. If an area requires more configuration, or if a validity check fails, then the section will read "Incomplete" and you will not be allowed to create a new build.
When updating your Google Play app you will be required to change the version number to a higher number than the previous build (eg. change 1.0 to 1.1). You will change the version number within your Build Settings under the App Identifiers section.
5. Test your updated app before submitting it to Google Play.
Note: For more information, please read the article "Android - Testing Your App Before Distribution."
6. Log into the Google Play Developer Console <https://play.google.com/apps/publish/> and click on the app you want to update.
9. In the window that appears, browse to the APK file you downloaded from the mag+ Publish portal and also edit the information of version number and whats new in this version and then Click on Review.
10. After Review, able to see the window of APK in this release information then click on "Start rollout to production" for submitting your new version for approval.
Note: When submitting your app to Google Play there is now a review process. Your Android app should be reviewed and then appear in the Google Play store within 24 hours, provided there are no problems discovered.
