I am a new developer. I have just published my first two apps on playstore. The second one displays ads as I have placed ads sdk in the gradle file. but my first app does not show any ads, because I published it as a free app on playstore without any ads. But now I want to add ads in my first app too. How can I do it ? Should I delete it and upload again ? Or can I upload a new version of it with ads ? This is the second app The second app is already showing ads successfully. This is the first app It was published as an app without ads. But now I want to place ads in it. Can I place the ad in an update ?
Simply to answer. Yes You can update new release of APK with Ads The updated version of the app should be signed with the same key used for signing the previous release else the APK you upload will be considered as new APK and not as updating one
