# Subscription States

Decide whether a user has access, and drive state aware UI, using `CustomerInfo` and `EntitlementInfo` on Android.

## Phase 1: Discover

Confirm what you are actually checking before you write code.

- Which entitlement identifier gates the feature? (for example `pro_access`)
- Do you need a plain access boolean, or do you also need to explain *why* the user has or lacks access (billing issue, canceled but still paid, paused)?
- Do you need the cached value (fast, possibly stale) or a freshly fetched value (server authoritative)?
- Are you refreshing UI once on launch, or reacting to live changes (purchase, restore, background refresh)?

If you only need access on/off, you only need `isActive`. Everything else is optional context.

## Phase 2: Plan

### Google's seven states versus RevenueCat's boolean

Rolling your own tracker with the Google Play Developer API means mapping seven subscription states and deciding which grant access.

| Google state | Grants access? |
|---|---|
| ACTIVE | yes |
| IN_GRACE_PERIOD | yes |
| CANCELED (before `expirationDate`) | yes |
| ON_HOLD | no |
| PAUSED | no |
| EXPIRED | no |
| PENDING | no |

RevenueCat computes this on the backend from the Google `SubscriptionPurchaseV2` resource and exposes the result as one field: `EntitlementInfo.isActive`. You read a boolean instead of implementing the state machine.

### What to read, and when

| Need | Field |
|---|---|
| Does the user have access right now? | `entitlement.isActive` |
| Will the subscription renew at period end? | `entitlement.willRenew` |
| When does paid access end? | `entitlement.expirationDate` |
| Is this a trial, intro, prepaid, or normal period? | `entitlement.periodType` |
| Is there a payment problem? | `entitlement.billingIssueDetectedAt` |
| Has the user canceled but still has time left? | `entitlement.unsubscribeDetectedAt` |
| Which store issued the entitlement? | `entitlement.store` |

### Decision rules

- Gate features on `isActive == true`. Nothing else.
- Use `billingIssueDetectedAt != null` to show a fix payment prompt.
- Use `unsubscribeDetectedAt != null` with `expirationDate` to show a renewal reminder while access is still valid.
- Use `!willRenew` (when no billing issue and no explicit cancel timestamp) to show a non renewing notice.

## Phase 3: Execute

### Read CustomerInfo and check access

```kotlin
val customerInfo = Purchases.sharedInstance.awaitCustomerInfo()
val hasAccess = customerInfo.entitlements["pro_access"]?.isActive == true
```

`awaitCustomerInfo()` returns the disk cache immediately, then refreshes from the network in the background. Entitlement checks stay fast, even offline.

### Force a fresh fetch when you must

Use this after a server side grant (for example, a support agent issued a promo).

```kotlin
val fresh = Purchases.sharedInstance.awaitCustomerInfo(
    fetchPolicy = CacheFetchPolicy.FETCH_CURRENT
)
```

### Drive state aware UI

`isActive` gates access; the other fields explain context.

```kotlin
fun updateUI(entitlement: EntitlementInfo?) {
    if (entitlement == null || !entitlement.isActive) {
        showSubscribeScreen(); return
    }
    showPremiumContent()
    when {
        entitlement.billingIssueDetectedAt != null -> showBillingIssueWarning()
        entitlement.unsubscribeDetectedAt != null ->
            entitlement.expirationDate?.let { showExpiryNotice(it) }
        !entitlement.willRenew -> showNonRenewingNotice()
    }
}
```

### Messaging guide by signal

| Signal on an active entitlement | Message to show |
|---|---|
| `billingIssueDetectedAt != null` | Payment problem, update method |
| `unsubscribeDetectedAt != null` | Access ends on `expirationDate` |
| `willRenew == false` (no other signal) | Will not renew this period |
| `periodType == TRIAL` or `INTRO` | Trial or intro pricing in effect |

### Identify the user for multi device

```kotlin
val result = Purchases.sharedInstance.awaitLogIn("your_user_id")
val customerInfo = result.customerInfo
val createdNewUser = result.created
```

`awaitLogIn()` merges anonymous purchases with the identified user. `logOut()` starts a fresh anonymous session.

## Phase 4: Verify

### Listen for CustomerInfo updates

Register a listener so UI reacts to purchases, restores, and background refreshes without manual polling.

```kotlin
Purchases.sharedInstance.updatedCustomerInfoListener =
    UpdatedCustomerInfoListener { info ->
        val active = info.entitlements["pro_access"]?.isActive == true
        updateAccessGate(active)
    }
```

The listener does not fire when the SDK starts with a cache hit and nothing changed. Always call `awaitCustomerInfo()` on launch in addition to setting the listener.

### Test matrix

Walk through each case and confirm the UI responds correctly.

| Case | Expected `isActive` | Expected UI |
|---|---|---|
| Fresh purchase | true | Premium content |
| Grace period (billing issue, still granted) | true | Premium + billing warning |
| Canceled, still before `expirationDate` | true | Premium + expiry notice |
| On hold | false | Subscribe screen |
| Paused | false | Subscribe screen |
| Expired | false | Subscribe screen |
| Pending (no payment yet) | false | Subscribe screen |

### Sanity checks

- Access gate flips correctly when the listener fires after a purchase.
- `FETCH_CURRENT` updates `CustomerInfo` after a backend grant (promo, refund, support action).
- After `logOut()`, `CustomerInfo` reflects an anonymous user and `isActive` resets accordingly.
- Offline launch still returns cached `CustomerInfo` and gates access without a network call.
