Google Play

Google Play can be connected to SolydFlow to support in-app purchases for Android applications distributed through Google Play.

With Google Play connected, SolydFlow provides the revenue infrastructure around the purchase lifecycle while your application works with a consistent transaction and entitlement layer.

Your Application
       ↓
   SolydFlow
       ↓
  Google Play
       ↓
Google Play Billing

Google Play remains responsible for processing the store purchase. SolydFlow manages the application-facing revenue flow around the purchase.

When to Use Google Play​

Google Play is appropriate when your Android application uses Google Play Billing for digital products or subscriptions distributed through Google Play.

For example:

Customer
   ↓
Android Application
   ↓
SolydFlow
   ↓
Google Play Billing
   ↓
Google Play

Google Play can also operate alongside other payment providers in the same SolydFlow project.

                        │
            ┌───────────┼───────────┐
            ↓           ↓           ↓
       Google Play    Apple       Stripe
            │           │           │
         Android       iOS        Web App

This allows an application to use different payment infrastructure depending on the platform and market.

How Google Play Fits Into SolydFlow​

The integration follows the same revenue infrastructure model used across SolydFlow providers.

                 Entitlement
                     ↓
              Application Access

Your application can work with SolydFlow's transaction and entitlement model rather than implementing separate revenue logic around every provider.

What Google Play Handles​

Google Play handles the store-side purchase operation.

This can include:

  • Google Play purchase processing
  • In-app purchase authorization
  • Subscription billing
  • Store transaction records
  • Purchase state
  • Subscription state
  • Google Play purchase information
  • Store-related purchase events

The exact capabilities and requirements depend on Google's current Google Play Billing infrastructure.

Always verify Google's current requirements before implementing a production integration.

What SolydFlow Handles​

SolydFlow provides the application-facing revenue infrastructure around the Google Play transaction.

This can include:

  • Connecting Google Play to your SolydFlow project
  • Associating purchases with products and packages
  • Tracking transactions
  • Processing store events
  • Verifying transaction information
  • Recovering transactions when expected events are missing
  • Maintaining a unified transaction view
  • Managing entitlements
  • Providing a consistent revenue model across providers

Prerequisites​

Before connecting Google Play to SolydFlow, you should have:

  1. A Google Play Console account
  2. An Android application configured for Google Play
  3. The required in-app products or subscriptions
  4. A SolydFlow project
  5. Products configured in SolydFlow
  6. Packages and pricing configured
  7. The required Google Play credentials or configuration

Google Play's developer and billing requirements must be satisfied before production purchases can be processed.

Google Play Product Configuration​

Google Play uses its own product identifiers for in-app products and subscriptions.

SolydFlow can provide an application-facing product and package structure above these provider-specific identifiers.

For example:

SolydFlow Product
└── Pro
    ├── Monthly
    └── Annual

Google Play
├── com.example.pro.monthly
└── com.example.pro.annual

This allows your application to maintain a consistent commercial model while Google Play-specific identifiers remain associated with the appropriate store products.

See:

Products →

Packages →

Products and Packages →

Google Play and Paywalls​

The customer typically sees your application's paywall before selecting an in-app purchase.

Customer
   ↓
Android Application
   ↓
SolydFlow Paywall
   ↓
Package
   ↓
Google Play Billing
   ↓
Google Play

The paywall communicates the product and package available to the customer.

Google Play then presents and processes the store purchase.

See:

Paywalls →

Google Play Purchase Flow​

A typical purchase lifecycle can be represented as:

Customer
   ↓
Select Package
   ↓
Application
   ↓
Google Play Billing
   ↓
Store Authorization
   ↓
Transaction
   ↓
SolydFlow
   ↓
Verification
   ↓
Entitlement
   ↓
Application Access

The transaction and entitlement should not be treated as permanently equivalent simply because a purchase was initially successful.

Later store events can change the customer's entitlement state.

Google Play and Asynchronous Events​

Store transactions can have lifecycle events that occur after the initial purchase.

For example:

Purchase
   ↓
Successful
   ↓
Subscription Active
   ↓
Later Store Event
   ↓
Subscription State Changes

SolydFlow therefore needs to account for the transaction lifecycle rather than treating the initial purchase as the end of the process.

Conceptually:

Google Play
     ↓
Store Event
     ↓
SolydFlow
     ↓
Transaction State
     ↓
Entitlement

See:

Provider Webhooks →

Event Handling →

Transaction Verification​

Store transactions should be verified before the application grants durable access to paid functionality.

Conceptually:

Google Play Transaction
         ↓
     Verification
         ↓
      SolydFlow
         ↓
   Transaction State
         ↓
      Entitlement

Verification helps ensure that the application is responding to a valid transaction rather than trusting an unverified client-side state.

See:

Transaction Verification →

Missing Store Events​

A transaction can exist on the provider side while the expected event is delayed or unavailable to the application.

For example:

Google Play
     ↓
Purchase Successful
     ↓
Store Event
     X

This can produce a mismatch:

Google Play
└── Purchased

Application
└── Pending

SolydFlow's recovery and verification layers can help resolve these situations.

       ↓

       ↓

Transaction Recovery →

Google Play Transaction State​

Google Play has its own transaction and subscription state.

SolydFlow maintains an application-facing transaction lifecycle.

These states may not always change at exactly the same time.

For example:

Google Play
└── Purchase Exists

SolydFlow
└── Verification Pending

After verification:

Google Play
└── Valid Purchase

SolydFlow
└── Successful

SolydFlow can use provider information, transaction verification, and store events to determine the appropriate application-facing state.

See:

Transaction States →

State Mismatches →

Google Play and Entitlements​

The most important application-facing result of an in-app purchase is often the entitlement it grants.

For example:

Google Play Purchase
        ↓
Transaction
        ↓
Verification
        ↓
Package
        ↓
Entitlement
        ↓
Premium Access

This separates the store transaction from the application's access-control decision.

If the customer has a valid entitlement, the application can grant the corresponding access.

See:

Entitlements →

Google Play Subscriptions​

Subscriptions introduce additional lifecycle events beyond the initial purchase.

Conceptually:

Purchase
   ↓
Active
   ↓
Renewal
   ↓
Renewed
   ↓
Renewal
   ↓
...

A subscription can also move into another state depending on events reported by Google Play.

Your application should therefore rely on the current verified transaction and entitlement state rather than assuming that the original purchase remains active forever.

Google Play and the Transaction Ledger​

Google Play provides store-side transaction information.

SolydFlow can maintain a unified transaction record for the application's revenue lifecycle.

Google Play
     ↓
Store Transaction
     ↓
  SolydFlow
     ↓
SolydFlow Transaction
     ↓
Unified Revenue Record

This becomes especially useful when the same application monetizes through multiple platforms.

                    SolydFlow
                        │
            ┌───────────┼───────────┐
            ↓           ↓           ↓
       Google Play    Apple       Stripe
            │           │           │
         Android       iOS        Web
            └───────────┼───────────┘
                        ↓
                  Unified Ledger

Google Play Alongside Other Providers​

A single application may have different payment infrastructure depending on the platform.

For example:

Android
   ↓
Google Play
   ↓
SolydFlow

iOS
   ↓
Apple
   ↓
SolydFlow

Web
   ↓
Stripe / Paystack / Other Provider
   ↓
SolydFlow

The application can still consume a consistent SolydFlow transaction and entitlement model.

This is one of the key benefits of placing SolydFlow above the provider layer.

Google Play and Regional Pricing​

Google Play manages store pricing and availability according to its billing infrastructure and configuration.

SolydFlow's product and package model should remain conceptually separate from provider-specific pricing configuration.

For example:

SolydFlow
└── Premium
    └── Monthly Package

Google Play
└── Play Product
    └── Store-specific Price

This allows SolydFlow to maintain the application-level commercial model while Google Play handles the store-specific purchase experience.

See:

Regional Pricing →

Multi-Currency →

Google Play and Recovery​

Consider a transaction where Google Play confirms a purchase but the application does not immediately receive or process the expected event.

Customer
   ↓
Google Play
   ↓
Purchase Completed
   ↓
Application Event Missing

SolydFlow can provide a recovery and verification layer:

Transaction
    ↓
Recovery
    ↓
Google Play Verification
    ↓
Resolved State
    ↓
Entitlement

This prevents individual applications from having to build the same transaction recovery logic independently.

See:

Recover →

Google Play Failover​

Google Play purchases are platform-specific.

They should not be treated like ordinary payment-provider failover where a transaction can simply be moved from one provider to another.

For example:

Android Application
       ↓
Google Play

should remain distinct from:

Web Application
       ↓
Stripe / Paystack / Other Provider

SolydFlow can unify the resulting transaction and entitlement data without pretending that every provider supports the same payment flow.

This distinction is important when designing multi-provider architectures.

Testing Google Play Purchases​

Use Google's supported testing environments before processing live purchases.

A typical testing flow is:

Development
    ↓
Google Play Test Environment
    ↓
SolydFlow Sandbox
    ↓
Test Purchase
    ↓
Verification
    ↓
Store Event Test
    ↓
Recovery Test
    ↓
Production

Test at least:

  • Successful purchases
  • Failed purchases
  • Pending transactions
  • Transaction verification
  • Subscription lifecycle events
  • Store event delivery
  • Missing events
  • Transaction recovery
  • Entitlement updates
  • Restore purchase scenarios

See:

Test Transactions →

Simulate Failures →

Testing Recovery →

Restore Purchases​

Customers may reinstall an application, switch devices, or otherwise need their previous purchases restored.

The application should be able to retrieve and verify eligible purchases and restore the appropriate entitlement.

Conceptually:

Customer
   ↓
Restore Purchases
   ↓
Google Play
   ↓
Transactions
   ↓
SolydFlow
   ↓
Verification
   ↓
Entitlement Restored

This allows access to be restored without treating the new application installation as a completely new purchase history.

Production Checklist​

Before using Google Play for live in-app purchases, verify:

Google Play​

  • The Google Play application is configured correctly
  • In-app products are configured
  • Subscription products are configured where applicable
  • Product identifiers match the intended packages
  • Production credentials/configuration are being used
  • Store event configuration is correct
  • Required Google Play requirements are satisfied

SolydFlow​

  • Google Play is connected to the correct project
  • Products are configured correctly
  • Packages are mapped correctly
  • Store product identifiers are configured correctly
  • Paywalls display the intended offerings
  • Transaction verification is working
  • Store events are processed
  • Recovery has been tested
  • Entitlements behave correctly

Security​

  • Secret credentials are protected
  • Store transaction information is validated
  • Production secrets are not exposed to clients
  • Access to provider configuration is restricted

See:

Production Checklist →

Refunds and Subscription Changes​

A Google Play purchase can change after the original purchase.

For example:

Purchase
   ↓
Active
   ↓
Store Event
   ↓
Subscription / Transaction State Changes
   ↓
SolydFlow
   ↓
Entitlement Update

The application should therefore respond to the current verified transaction and entitlement state rather than permanently granting access based only on the original purchase.

Compliance​

Google Play handles the platform-side requirements associated with its store and billing infrastructure.

However, using Google Play does not automatically remove all legal or regulatory responsibilities from your business.

Depending on your business model and target markets, you may need to consider:

  • Taxes
  • Consumer protection
  • Data protection
  • Business requirements
  • Platform policies
  • Local regulations

See:

Compliance →

Troubleshooting​

When a Google Play purchase does not produce the expected result, trace the complete flow.

Customer
   ↓
Paywall
   ↓
Google Play Purchase
   ↓
Store Transaction
   ↓
Verification
   ↓
SolydFlow
   ↓
Transaction
   ↓
Entitlement

Check:

  1. Did the customer initiate the purchase?
  2. Did Google Play create the transaction?
  3. Was the transaction completed?
  4. Was the transaction verified?
  5. Was the expected store event received?
  6. Did SolydFlow process the event?
  7. What transaction state does SolydFlow show?
  8. Was the entitlement granted?
  9. If the purchase was restored, was the entitlement restored correctly?

See:

Troubleshooting →

Key Principle​

Google Play processes the store purchase. SolydFlow manages the application revenue lifecycle around the purchase.

Your application should not need to maintain separate transaction and entitlement logic for every store and payment provider.
