php小編百草提供你解決Android Studio Java應用程式內購買錯誤和問題的方法。在開發應用程式時，應用程式內購買是一項常見的功能，但許多開發者在實現時可能會遇到各種問題。本文將分享解決應用程式內購買錯誤和問題的有效方法，幫助你順利完成應用程式的開發和發布。無論是遇到商品無法購買、購買流程中斷或支付驗證失敗等問題，我們都將給予詳細的解決方案，幫助你快速解決問題，提升應用程式的使用者體驗。
在我的應用程式中，我使用此程式庫新增應用程式內購買。
這就是我的活動程式碼：
public class InfoController extends AppCompatActivity {
private static final String PREFS_NAME = "TEST_MyPrefsFile";
private static final String FIRST_TIME_KEY = "TEST_isFirstLaunch";
private static final String IS_PRO_KEY = "TEST_isPro";
private boolean isPro() {
SharedPreferences preferences = getSharedPreferences(PREFS_NAME, Context.MODE_PRIVATE);
return preferences.getBoolean(IS_PRO_KEY, false);
}
private void setProUser(boolean isPro) {
SharedPreferences preferences = getSharedPreferences(PREFS_NAME, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = preferences.edit();
editor.putBoolean(IS_PRO_KEY, isPro);
editor.apply();
}
private Button upgradeButton;
String base64String = "xxxxxxxxxxxxxxxxxxxxxxxxxxxx";
private BillingConnector billingConnector;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_info);
upgradeButton = findViewById(R.id.upgradeButton);
if (!isPro()) {
upgradeButton.setText("Click here to upgrade to Pro");
initializeBillingClient();
} else {
upgradeButton.setEnabled(false);
upgradeButton.setText("User is Pro");
}
}
private void initializeBillingClient() {
List<String> nonConsumableIds = new ArrayList<>();
nonConsumableIds.add("com.xxxx.pro"); // Replace with your actual non-consumable product ID
billingConnector = new BillingConnector(this, base64String)
.setNonConsumableIds(nonConsumableIds)
.autoAcknowledge()
.enableLogging()
.connect();
billingConnector.setBillingEventListener(new BillingEventListener() {
@Override
public void onProductsFetched(@NonNull List<ProductInfo> productDetails) {
}
//this IS the listener in which we can restore previous purchases.
// Code will execute on InfoController.java appear. If pro is already purchased, unlock pro features.
@Override
public void onPurchasedProductsFetched(@NonNull ProductType productType, @NonNull List<PurchaseInfo> purchases) {
String purchasedProduct;
boolean isAcknowledged;
for (PurchaseInfo purchaseInfo : purchases) {
purchasedProduct = purchaseInfo.getProduct();
isAcknowledged = purchaseInfo.isAcknowledged();
if (!isPro()) {
if (purchasedProduct.equalsIgnoreCase("com.xxxx.pro")) {
if (isAcknowledged) {
// CustomToast.makeText(InfoController.this, "The previous purchase was successfully restored.", Toast.LENGTH_SHORT).show();
// setProUser(true);
Toast.makeText(InfoController.this, "isAcknowledged", Toast.LENGTH_SHORT).show();
}
}
}
}
}
//this IS NOT the listener in which we'll give user entitlement for purchases (see ReadMe.md why)
@Override
public void onProductsPurchased(@NonNull List<PurchaseInfo> purchases) {
}
//this IS the listener in which we'll give user entitlement for purchases (the ReadMe.md explains why)
@Override
public void onPurchaseAcknowledged(@NonNull PurchaseInfo purchase) {
String acknowledgedProduct = purchase.getProduct();
if (acknowledgedProduct.equalsIgnoreCase("com.xxxx.pro")) {
Toast.makeText(InfoController.this, "The purchase was successfully made.", Toast.LENGTH_SHORT).show();
setProUser(true);
upgradeButton.setEnabled(false);
upgradeButton.setText("User is Pro");
}
}
@Override
public void onPurchaseConsumed(@NonNull PurchaseInfo purchase) {
}
@Override
public void onBillingError(@NonNull BillingConnector billingConnector, @NonNull BillingResponse response) {
switch (response.getErrorType()) {
case ACKNOWLEDGE_WARNING:
//this response will be triggered when the purchase is still PENDING
CustomToast.makeText(InfoController.this, "The transaction is still pending. Please come back later to receive the purchase!", Toast.LENGTH_SHORT).show();
break;
case BILLING_UNAVAILABLE:
case SERVICE_UNAVAILABLE:
CustomToast.makeText(InfoController.this, "Billing is unavailable at the moment. Check your internet connection!", Toast.LENGTH_SHORT).show();
break;
case ERROR:
CustomToast.makeText(InfoController.this, "Something happened, the transaction was canceled!", Toast.LENGTH_SHORT).show();
break;
case ITEM_ALREADY_OWNED:
Toast.makeText(InfoController.this, "The purchase has already been made.", Toast.LENGTH_SHORT).show();
setProUser(true);
upgradeButton.setEnabled(false);
upgradeButton.setText("User is Pro");
break;
case ITEM_NOT_OWNED:
//TODO - failure to consume since item is not owned
break;
}
}
});
}
public void onUpgradeButtonClick(View view) {
billingConnector.purchase(InfoController.this, "com.xxxx.pro");
}
}當我在應用程式購買中進行測試時，我使用促銷代碼（因為我的帳戶沒有連接卡）。
因此，當我開啟此活動時，什麼也沒有顯示。我按upgradebutton，彈出升級提示，我選擇促銷代碼並輸入促銷代碼，點擊下一步，它告訴我價格為0，我按確認。此後，購買提示視窗將關閉，沒有任何反應。沒有顯示 toast 訊息，升級按鈕文字仍然顯示：click here to upgrade to pro。
如果我現在關閉應用程序，重新打開它並轉到 infocontroller（此活動），則會顯示 toast 訊息 isacknowledged。
所以我的問題是：為什麼購買完成後沒有任何反應，但是當我購買後再次打開活動時，它顯示isacknowledged？
處理前檢查確認狀態：
@override
public void onpurchasedproductsfetched(@nonnull producttype producttype, @nonnull list<purchaseinfo> purchases) {
for (purchaseinfo purchaseinfo : purchases) {
string purchasedproduct = purchaseinfo.getproduct();
if (!ispro() && purchasedproduct.equalsignorecase("com.xxxx.pro")) {
if (!billingconnector.ispurchaseditemacknowledged(purchaseinfo)) {
// here is the code of purchase processing
}
}
}
}也會確認邏輯從 onpurchaseacknowledged 方法移至 onpurchasedproductsfetched 方法。這可能會有所幫助。
@Override
public void onPurchasedProductsFetched(@NonNull ProductType productType, @NonNull List<PurchaseInfo> purchases) {
for (PurchaseInfo purchaseInfo : purchases) {
String purchasedProduct = purchaseInfo.getProduct();
if (!isPro() && purchasedProduct.equalsIgnoreCase("com.xxxx.pro")) {
// here is the code of purchase processing
handlePurchase(purchaseInfo);
}
}
}
private void handlePurchase(PurchaseInfo purchaseInfo) {
String acknowledgedProduct = purchaseInfo.getProduct();
if (acknowledgedProduct.equalsIgnoreCase("com.xxxx.pro")) {
Toast.makeText(InfoController.this, "The purchase was successfully made.", Toast.LENGTH_SHORT).show();
setProUser(true);
upgradeButton.setEnabled(false);
upgradeButton.setText("User is Pro");
}
