UPDATE 3 (now live)
UPDATE 2 (coming soon)
I got an email from the Google Play Store this morning about updating one of my apps and this final point caught my attention:
I know a number of people have said that they couldn’t submit their app after uploading a new version, it turns our your might need to make a minor change to your store listing before you can click the button. The full message reads:
Click SUBMIT UPDATE. (If the submit button is grayed out, make a minor change to your store listing to activate the button. For example, add a space after your app title and then delete it).
Back in December 2017 Google Announced that they would be increasing the target API level to improve the overall security of Android apps and the Play store.
When is the API level increasing?
This increase will be phased in during the second half of this year. Google are giving everyone lots of notice to make sure that they’re up to speed with the changes.
From August 2018 all new apps must have a minimum target level of 26 (Android 8)
From November all existing apps must target API level 26 (or higher)
How does that affect me?
If you don’t plan on publishing to the Play store then this doesn’t affect you.
If you are publishing a new app in the Play store then from August 2018 onwards your app must be Android 8 or higher.
If you are updating an existing app in the Google Play store from November 2018 onwards then your app must be Android 8 or higher.
Can I still upload/update apps?
During the publication/update process you will see several warnings notifying about the impending changes, but you are still able to upload and publish during this time.
1. Upload Your .apk
Create a new production release just like you usually would and upload your .apk. You will see the following message:
2. Add Release Notes
You have to add some release notes before you can proceed to the review stage:
Once you’ve added some release note you can click the “Review” button:
At the review stage you get a second notification about the API level changes that will happen in August/November, but these warnings don’t prevent you from rolling out your app.
4. Rollout to Production
Click the “Start Rollout to Production” button…
…you get a third and final warning about the API level changes. Click “confirm” to continue.
That’s it. You app or updated app will be reviewed and released in due course.
