Warnings Your app currently targets API level 25 and must target at least API level 26 to ensure it is built on the latest APIs optimized for security and performance.
From August 2018, new apps must target at least Android 8.0 (API level 26). From November 2018, app updates must target Android 8.0 (API level 26).
Tip: Change your app's target API level. Learn how.
I am using Cordova and Ionic 3.
Just built the app using: ionic cordova build android --release-prod
What should I do, ignore this or fix and how?
Thanks.
You can update your cordova-android to 7.0.0 as that's the version that uses SDK 26 as target, or you can update to cordova-android 7.1.4, as it targets SDK 27.
You can do it by removing the platform and adding it again specifying the version to use like this: (if not using ionic, remove the ionic word from both commands)
ionic cordova platform rm android
ionic cordova platform add android@7.1.4
If you don't want or can't update, you can try to set the target SDK with this preference in the config.xml
<preference name="android-targetSdkVersion" value="26"/>
And then run ionic cordova prepare
This is because Google has made it compulsory for apps to target at least 26 API level by August 2018 for new apps and November 2018 for updating apps.
