I have implemented in-app-purchase. The issue is that the billing dialog billingClient.launchBillingFlow not showing in some devices. First I tested in android 8 and everything works good but when I tested in android 9 and the billing dialog is not showing.
Here is the code
billingClient = BillingClient.newBuilder(this)
.enablePendingPurchases()
.setListener(this).build();
billingClient.startConnection(new BillingClientStateListener() {
@Override
public void onBillingSetupFinished(@NonNull BillingResult billingResult) {
if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
List<String> skuList = new ArrayList<>();
skuList.add(ITEM_SKU_diamond_500);
final SkuDetailsParams.Builder params = SkuDetailsParams.newBuilder();
params.setSkusList(skuList).setType(BillingClient.SkuType.INAPP);
billingClient.querySkuDetailsAsync(params.build(), new SkuDetailsResponseListener() {
@Override
public void onSkuDetailsResponse(@NonNull BillingResult billingResult, List<SkuDetails> skuDetailsList) {
if (skuDetailsList != null && billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
for (SkuDetails skuDetails : skuDetailsList) {
String sku = skuDetails.getSku();
String price = skuDetails.getPrice();
final BillingFlowParams params = BillingFlowParams.newBuilder()
.setSkuDetails(skuDetails)
.build();
if (ITEM_SKU_diamond_500.equals(sku)) {
premiumUpgradePrice = price;
firstBtn500(params);
}
//clickHandler(skuDetails, sku);
}
} else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.ERROR) {
Toast.makeText(DiamondsActivity.this, "Error", Toast.LENGTH_SHORT).show();
}
}
});
} else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.SERVICE_TIMEOUT) {
Toast.makeText(DiamondsActivity.this, "Service timeout", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(DiamondsActivity.this, "Failed to connect to the billing client", Toast.LENGTH_SHORT).show();
}
}
@Override
public void onBillingServiceDisconnected() {
Toast.makeText(DiamondsActivity.this, "Disconnected from the client", Toast.LENGTH_SHORT).show();
}
});
private void firstBtn500(final BillingFlowParams params) {
firstPurchaseBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(DiamondsActivity.this, "OK: 1", Toast.LENGTH_SHORT).show();
//The toast message is showing.
// but the billing dialog is not showing
billingClient.launchBillingFlow(DiamondsActivity.this, params);
}
});
}
@Override
public void onPurchasesUpdated(@NonNull BillingResult billingResult, @Nullable List<Purchase> purchases) {
if (purchases != null && billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
for (Purchase purchase : purchases) {
handlePurchases(purchase);
}
} else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.USER_CANCELED) {
Toast.makeText(this, "Purchased Canceled", Toast.LENGTH_SHORT).show();
}
}
private void handlePurchases(final Purchase purchase) {
if (purchase.getPurchaseState() == Purchase.PurchaseState.PURCHASED) {
// Todo :Consume the purchase async
ConsumeParams consumeParams = ConsumeParams.newBuilder()
.setPurchaseToken(purchase.getPurchaseToken())
.build();
ConsumeResponseListener consumeResponseListener = new ConsumeResponseListener() {
@Override
public void onConsumeResponse(BillingResult billingResult, @NonNull String purchaseToken) {
Toast.makeText(DiamondsActivity.this, "Purchase successful", Toast.LENGTH_SHORT).show();
if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
if (purchase.getSku().equalsIgnoreCase(ITEM_SKU_diamond_500)) {
Toast.makeText(DiamondsActivity.this, "Thank you for purchasing!", Toast.LENGTH_SHORT).show();
handleAdditionOfData(500);
}
}
}
};
billingClient.consumeAsync(consumeParams, consumeResponseListener);
} else if (purchase.getPurchaseState() == Purchase.PurchaseState.PENDING) {
Toast.makeText(this, "Purchase pending", Toast.LENGTH_SHORT).show();
}
}
Update it with this method:
private void firstBtn500(final BillingFlowParams params) {
firstPurchaseBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(DiamondsActivity.this, "OK: 1", Toast.LENGTH_SHORT).show();
BillingFlowParams billingFlowParams = BillingFlowParams.newBuilder()
.setSkuDetails(skuDetails)
.build();
int responseCode = billingClient.launchBillingFlow(activity, params);
}
});
}
