如何在App Starts - Play Billing 1.0中查询用户购买 _Billing

【如何在App Starts - Play Billing 1.0中查询用户购买】得意犹堪夸世俗，诏黄新湿字如鸦。这篇文章主要讲述如何在App Starts - Play Billing 1.0中查询用户购买相关的知识，希望能为你提供帮助。
这是我的账单管理员

public class BillingManager implements PurchasesUpdatedListener { private BillingClient mBillingClient; private Activity mActivity; public BillingManager(Activity activity) { mActivity = activity; mBillingClient = BillingClient.newBuilder(mActivity).setListener(this).build(); startServiceConnectionIfNeeded(null); }private void startServiceConnectionIfNeeded(final Runnable executeOnSuccess) { if (mBillingClient.isReady()) { if (executeOnSuccess != null) { executeOnSuccess.run(); } } else { mBillingClient.startConnection(new BillingClientStateListener() { @Override public void onBillingSetupFinished(@BillingClient.BillingResponse int billingResponse) { if (billingResponse == BillingClient.BillingResponse.OK) { Log.i(TAG, "onBillingSetupFinished() response: " + billingResponse); if (executeOnSuccess != null) { executeOnSuccess.run(); } } else { Log.w(TAG, "onBillingSetupFinished() error code: " + billingResponse); } }@Override public void onBillingServiceDisconnected() { Log.w(TAG, "onBillingServiceDisconnected()"); } }); } }

以下监听器仅在完成Google Play库时执行

@Override public void onPurchasesUpdated(int responseCode, @Nullable List< Purchase> purchases) { Log.d(TAG, "onPurchasesUpdated: ResponseCode = "+ responseCode); Log.d(TAG, "onPurchasesUpdated: Purchase = "+purchases); if (responseCode == BillingClient.BillingResponse.OK & & purchases != null) { //if user purchased something } else if (responseCode == BillingClient.BillingResponse.USER_CANCELED) { // Handle an error caused by a user cancelling the purchase flow. } else { // Handle any other error codes. } }

答案除了成功的onBillingSetupFinished回调之外，在你的活动的onCreate内部甚至更好的onResume（这将防止在应用之间切换时丢失购买的潜在问题）。

例如。 queryPurchase在那里被触发here和here。
