Android in App Subscription cases to be handle

Question

I have 2 subscription in android

Basic One with 3 base plan (less feature) 1 month prepaid 6 month prepaid 12 month prepaid

Premium one with 3 base plan (more feature) 1 month auto renewal 6 month prepaid 12 month prepaid

Scenario 1 I have to upgrade 1 month basic to 12 month basic -- (this should work as extend mean increase end date) scenario 2 I have to upgrade 1 month basic to 12 month premium -- (if user doing in between upgradation then this system has calculate remaining duration as per new plan , add that much extra as subscription end date)

Also make sure for Scenario 2 , there should old subscription should be termination there is no 2 active subscription at same time

To achieve this Should I create 2 subscription,

1. Basic one - with 3 base plan( 1,6,12 month prepaid)

2. Premium one - with 3 base plan( 1 month renewal, 6 and 12 prepaid)

Or should I create single subscription with 6 based plan

1 month basic prepaid 6 month basic prepaid 12 month basic prepaid 1 month premium auto renewal 6 month premium prepaid 12 month premium prepaid

I don't want 2 active subscription at same time

Answer 1

You should create 2 separate subscriptions, that would be best in your scenarios. The in-app billing automatically detects when the user upgrade his plan from basic to premium. Although you need to code according to your cases.
