| `GrowSurfWindowResourcesIcon` | `type`, `imageUrl` | | `GrowSurfWindowResource` | `id`, `type`, `title`, `description`, `category`, `url`, `text`, `file` | | `GrowSurfWindowResourceFile` | `fileName`, `mimeType`, `bytes` | | `GrowSurfWindowResourceDownloadResponse` | `url`, `expiresIn` | | `GrowSurfPayoutSettings` | `provider`, `paypalEmailAddress`, `canRequestPaypalConfirmEmail`,

`GrowSurfPayoutDestinationProvider` | `provider`, `providerDisplayName`, `status`, `claimEmail`, `needsRepairReason`, `canConfirm` | | `GrowSurfTaxInfo` | `status`, `formType`, `residencyCountryCode`, `vatNumber`, `statusReason`, `payoutSettings` | | `GrowSurfTaxInfoRefreshPayoutSettings` | `hostedActions`, `requiredActions` | | `GrowSurfTaxSessionResponse` | `hostedUrl`, `status` | | `GrowSurfTaxInfoSaveResponse` | `success`, `taxInfo` | | `GrowSurfLeaderboardResponse` | `participants`, `nextKey`, `page`, `hasMore` | | `GrowSurfLeaderboardParticipant` | `id`, `rank`, `monthlyRank`, `prevMonthlyRank`, `email`, `isWinner`, `referralCount`, `monthlyReferralCount`, `prevMonthlyReferralCount`, `pendingReferralCount`, `revenueAmount`, `commissionAmount` | | `GrowSurfReferralSummary` | `referrals`, `leads`, `expiredReferrals`, `clicks`, `rewardsEarned`, `pendingRewards`, `invitesSent`, `currencyISO` | | `GrowSurfAffiliateSummary` | `referralRevenue`, `totalPaidOut`, `upcomingPayout`, `referrals`, `leads`, `clicks`, `currencyISO` | | `GrowSurfCommissionsResponse` | `commissions`, `totalCount`, `totalAmount`, `summary`, `nextId` | | `GrowSurfCommission` | `id`, `amount`, `currencyISO`, `status`, `holdDuration`, `createdAt`, `amountInCampaignCurrency`, `saleAmountInCampaignCurrency`, `campaignCurrencyISO`, `unread` | | `GrowSurfPayoutsResponse` | `payouts`, `totalCount`, `totalAmount`, `summary`, `nextId` | | `GrowSurfPayout` | `id`, `amount`, `currencyISO`, `status`, `paymentMethod`, `queuedAt`, `reversedAt`, `createdAt`, `amountInCampaignCurrency`, `campaignCurrencyISO`, `unread` | `GrowSurfWindowResource.type` is `FILE`, `LINK`, or `TEXT`. Items keep the server-authorized order. `category` can be `null`. A FILE contains only safe display metadata; call `getParticipantResourceDownloadUrl(resourceId)` when the participant opens it. The response never includes private storage coordinates or a durable file URL. {% hint style="info" %} `GrowSurfWindowCampaign.design` carries the raw `participantAvatarStyle` value for custom screens. It is `CHARACTERS`, `INITIALS`, `ANIMALS`, or `GRADIENT`. The built-in window renders it automatically. Treat a missing or unknown value as `INITIALS`. {% endhint %} {% hint style="info" %} `payoutDestinations` is `null` when no payout provider applies to the participant. If you build your own settings UI, render `providerDisplayName` instead of hardcoding a provider name, show the payout method picker when `requiresChoice` is `true`, and show the confirm action only when that provider's `canConfirm` is `true`. The PayPal-specific `provider` and `paypalEmailAddress` fields still work as before. {% endhint %} ## Advanced interfaces and stores Use these APIs for tests or custom storage/transport integrations. | Type | Public methods | | ---------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------- | | `GrowSurfCallback` | `onSuccess(result)`, `onError(error)` | | `GrowSurfTokenStore` | `getSessionToken()`, `getParticipantToken()`, `saveSessionToken(token)`, `saveParticipantToken(token)`, `clear()` | | `GrowSurfAttributionStore` | `getAttribution()`, `saveAttribution(attribution)`, `clearAttribution()`, `hasCheckedDeferredDeepLink()`, `markDeferredDeepLinkChecked()` | | `GrowSurfMobileInstanceIdStore` | `getMobileInstanceId()` | | `GrowSurfWindowCacheStore` | `getWindow(cacheKey, nowMillis)`, `saveWindow(cacheKey, windowJson, expiresAtMillis)`, `clear()` | | `GrowSurfInstallReferrerClient` | `getInstallReferrer()` | | `GrowSurfHttpTransport` | `execute(request)` | | `GrowSurfHttpRequest` | `method`, `url`, `headers`, `body`, `timeoutMillis` | | `GrowSurfHttpResponse` | `statusCode`, `body` | | `EncryptedPreferencesGrowSurfTokenStore` | Encrypted token store used by default. Clears only GrowSurf token data after confirmed unrecoverable crypto state. | | `PreferencesGrowSurfAttributionStore` | SharedPreferences-backed attribution store used by default. | | `PreferencesGrowSurfMobileInstanceIdStore` | SharedPreferences-backed mobile instance ID store used by default. | | `PreferencesGrowSurfWindowCacheStore` | SharedPreferences-backed window cache store. | | `EncryptedPreferencesGrowSurfWindowCacheStore` | Encrypted window cache store used by default. | | `UrlConnectionGrowSurfHttpTransport` | Default HTTP transport. | | `PlayStoreGrowSurfInstallReferrerClient` | Default Google Play Install Referrer client. | ## Android backup rules Android backs up `SharedPreferences`, but every GrowSurf preference file is device-scoped or regenerable, and a restored copy causes problems rather than preserving anything useful. Exclude all six from cloud backup and device transfer: | File | Why a restored copy is harmful | | ------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------ | | `growsurf_tokens.xml` | Encrypted. Android does not back up the Keystore key, so the restored ciphertext is unreadable. | | `growsurf_window_cache_encrypted.xml` | Encrypted, same reason. | | `growsurf_attribution.xml` | A restored "already checked" flag makes the SDK skip the Install Referrer query, so a genuinely new referred install loses its referral with no error. | | `growsurf_identity.xml` | Holds the per-install id. Restoring it clones one install identity onto a second device. | | `growsurf_window_cache.xml` | Cleartext cache. Regenerable, and a restored copy is stale. | | `growsurf_participant_engagement.xml` | Holds pending participant engagement for this install. Restoring it can replay old portal or share activity on another device. | If your app does not have backup rules, point the `` element in your manifest to the rules included with the SDK: ```xml ``` Android supports one app-wide file for each rule type. If your app already has either file, keep your existing rules and add all six GrowSurf exclusions to it. Do not replace exclusions required by another SDK. ## Errors The SDK throws: * `GrowSurfException` for SDK state errors such as missing participant tokens. * `GrowSurfHttpException` for non-2xx HTTP responses. Exposes a `statusCode: Int` property and the response body as the exception message. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.growsurf.com/developer-tools/android-sdk/models-and-errors.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
