问题
Hi I have I implemented inapp billing V3 for one year subscription for a item using android-inapp-billing-v3. I want to show remaining days in my app. I am calling getSubscriptionTransactionDetails to get Transaction details for the product but it always returns null. here is my code.
private BillingProcessor startInappCheck(){
bp = new BillingProcessor(mContext, BASE64ENCODEDPUBLICKEY, new BillingProcessor.IBillingHandler() {
@Override
public void onProductPurchased(String productId, TransactionDetails details) {
LogUtils.e(TAG, "onProductPurchased :" +productId);
// showToast("onProductPurchased: " + productId);
}
@Override
public void onBillingError(int errorCode, Throwable error) {
LogUtils.e(TAG, "onBillingError :" +errorCode);
}
@Override
public void onBillingInitialized() {
// showToast("onBillingInitialized");
readyToPurchase = true;
try{
SkuDetails subs = bp.getSubscriptionListingDetails(SUBSCRIPTION_ID);
LogUtils.d(TAG, "Owned Subscription: " + subs.toString());
TransactionDetails tr = bp.getSubscriptionTransactionDetails(SUBSCRIPTION_ID);
LogUtils.d(TAG, "Owned Subscription: " + tr.toString());
}catch (Exception e) {
// TODO: handle exception
}
}
@Override
public void onPurchaseHistoryRestored() {
// showToast("onPurchaseHistoryRestored");
for(String sku : bp.listOwnedSubscriptions()){
LogUtils.d(TAG, "Owned Subscription: " + sku);
}
// showToast("onPurchaseHistoryRestored");
}
});
return bp;
}
I called this method from onCreate.
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
if (!bp.handleActivityResult(requestCode, resultCode, data))
super.onActivityResult(requestCode, resultCode, data);
}
My subscription item button implemented in a fragment . One more problem I found that after successful subscription the onProductPurchased not get called but I have implemented the logic in onResume to update UI if bp.isSubscribed(SUBSCRIPTION_ID) returns true. Please tell me how to get subscription initiated date and expiry date.

I want to give Ans to my own que's ans, So that if some one looking for the same can find the solution.
After lots of google I did not find a exact solution I was looking for So I create a method in BillingProcessor class in iabv3 library project which returns a Bundle with Purchases details, in which i get the purchased date. Now I am able to find the expiry date with this. The method looks like below
public Bundle getPurchases(){
if (!isInitialized())
return null;
try{
return billingService.getPurchases(Constants.GOOGLE_API_VERSION, contextPackageName, Constants.PRODUCT_TYPE_SUBSCRIPTION, null);
}catch (Exception e) {
e.printStackTrace();
}
return null;
}

I have used this code for getting the purchase details in the Billing Processor Library .
TransactionDetails transactionDetails = bp.getSubscriptionTransactionDetails(channelModel.getAndroidProductId());
Log.d(TAG, "initializePaymentSetup: " + transactionDetails.toString());
Log.d(TAG, "initializePaymentSetup: " + transactionDetails.purchaseInfo.toString());
transactionDetails.purchaseInfo.purchaseData// this will return the purchase date

I'm using this:
@Nullable
public Date getSubscriptionRenewingDate(String sku) {
// Get the Purchase object:
Purchase purchase = null;
Purchase.PurchasesResult purchasesResult = _billingClient.queryPurchases(BillingClient.SkuType.SUBS);
if (purchasesResult.getPurchasesList() != null) {
for (Purchase p : purchasesResult.getPurchasesList()) {
if (p.getSku().equals(sku) && p.getPurchaseState() == Purchase.PurchaseState.PURCHASED && p.isAutoRenewing()) {
purchase = p;
break;
}
}
}
// Get the SkuDetails object:
SkuDetails skuDetails = null;
for (SkuDetails s : _skuDetails) { // _skuDetails is an array of SkuDetails retrieved with querySkuDetailsAsync
if (s.getSku().equals(sku)) {
skuDetails = s;
break;
}
}
if (purchase != null && skuDetails != null) {
Date purchaseDate = new Date(purchase.getPurchaseTime());
Calendar calendar = Calendar.getInstance();
calendar.setTime(purchaseDate);
Date now = new Date();
while (calendar.getTime().before(now)) {
switch (skuDetails.getSubscriptionPeriod()) {
case "P1W": calendar.add(Calendar.HOUR, 7*24); break;
case "P1M": calendar.add(Calendar.MONTH, 1); break;
case "P3M": calendar.add(Calendar.MONTH, 3); break;
case "P6M": calendar.add(Calendar.MONTH, 6); break;
case "P1Y": calendar.add(Calendar.YEAR, 1); break;
}
}
return calendar.getTime();
}
return null;
}
