I have uploaded by apk to beta testing as draft and added google groups email to let users test it. But i dont know how to give them access to apk. It says there sohuld be a opt-in link but there is none. Does anyone have idea ?
Hello,
You have to create a Google Group or a Google+ Community and let your users subscribe to the group or the community (check your community settings) or add the account address to the members.
Than, you provide them the link to the group or the community (the one Google Play provides when uploading your beta apk) and they will be able to download the APK from Google Play and receive the updates
OK so you have to go to your Apk's page at Google Play. Select the level of testing ("alpha" or "beta"). Click on "Manage list of testers" Under the level (alpha or beta) and a pop-up will open.
On that pop-up, you will see the link to your page to allow the users to install the apk the first time. The link is something like : https://play.google.com/apps/testing/[packageName]
