如何进一步测试Android游戏中的gdx-pay实现？

Hey there! Let's walk through what's happening with your gdx-pay integration and how to make sure your in-app purchases work as expected in the sandbox environment.

First, What That Log Means #

The log D/c: In App Purchasing SDK - Sandbox Mode: sendPurchaseRequest is actually a good sign! It tells you that:

• The gdx-pay library is correctly initialized and connected to Google Play's Billing SDK
• The sandbox mode is active (which is exactly what you want for testing before release)
• The SDK is successfully sending a purchase request to Google's servers

Why You're Not Seeing the Payment Popup #

The missing password/confirmation popup is almost always related to incomplete sandbox setup, not a problem with your gdx-pay code. Here's what you need to fix:

• Use a dedicated test account: You can't test purchases with your main developer account. Head to your Google Play Console, go to Testing > License testing, and add a separate Google account as a licensed tester. Log into this account on your test device.
• Set up test products in Play Console: Even if your app isn't published, you need to create the in-app products (managed products/subscriptions) in the Play Console under Monetization > Products. Make sure the product IDs in your gdx-pay code match exactly what you created here.
• Use a compatible device: Test on a physical Android device with the latest Google Play app installed, or an emulator that uses the "Google APIs" system image (regular emulators don't include Google Play services needed for billing).

How to Verify the Transaction Flow Works #

Even without the popup, you can confirm your integration is working:

1. Add logging to purchase callbacks: In your PurchaseObserver implementation, add detailed logs to methods like handlePurchaseSuccessful, handlePurchaseFailed, and handleInventoryQueryResult. If you see handlePurchaseSuccessful trigger after sending a request, the sandbox transaction is completing behind the scenes.
2. Query inventory manually: Call purchaseManager.queryInventory() and check if it returns your test product. This confirms that gdx-pay can communicate with Google's servers to fetch product details.

Is Your Current State "Normal"? #

Yes, for an unconfigured sandbox environment! The log proves your basic gdx-pay integration is functional. The only missing pieces are the Play Console setup and test account configuration. Once those are in place, you'll see the payment popup and be able to complete test purchases without real charges.
