I am adding a in app purchase in my coding, it\'s working well while purchase but gives error and application closes when I try to add Restore_Transaction code when applicat
I found the answer to my question, thanx to anddev
You have to check for purchases not to be null
public static void verifyPurchase(String signedData, String signature) {
ArrayList<VerifiedPurchase> purchases = BillingSecurity.verifyPurchase(
signedData, signature);
if (purchases != null && !purchases.isEmpty()) {
latestPurchase = purchases.get(0);
confirmTransaction(new String[] { latestPurchase.notificationId });
if (mCompletedHandler != null) {
mCompletedHandler.sendEmptyMessage(0);
} else {
Log
.e(
TAG,
"verifyPurchase error. Handler not instantiated. Have you called setCompletedHandler()?");
}
}
}
and in Confirm_Notification u hav to check for
if (notifyIds[0] != null)
You can use the below code to get purchase history:
public static ArrayList<VerifiedPurchase> verifyPurchase(String signedData,
String signature) {
if (signedData == null) {
//Log.e(TAG, "data is null");
return null;
}
if (Constans.DEBUG) {
//Log.i(TAG, "signedData: " + signedData);
}
boolean verified = false;
if (!TextUtils.isEmpty(signature)) {
/**
* Compute your public key (that you got from the Android Market
* publisher site).
*
* Instead of just storing the entire literal string here embedded
* in the program, construct the key at runtime from pieces or use
* bit manipulation (for example, XOR with some other string) to
* hide the actual key. The key itself is not secret information,
* but we don't want to make it easy for an adversary to replace the
* public key with one of their own and then fake messages from the
* server.
*
* Generally, encryption keys / passwords should only be kept in
* memory long enough to perform the operation they need to perform.

String productId = jElement.getString("productId");
String packageName = jElement.getString("packageName");
long purchaseTime = jElement.getLong("purchaseTime");

String notifyId = null;
if (jElement.has("notificationId")) {
notifyId = jElement.getString("notificationId");
}
String developerPayload = jElement.optString(
"developerPayload", null);
// If the purchase state is PURCHASED, then we require a
// verified nonce.
if (purchaseState == PurchaseState.PURCHASED && !verified) {
continue;
}
purchases.add(new VerifiedPurchase(purchaseState, notifyId,
productId, orderId, purchaseTime, developerPayload));

You can call this method from the below method in BillingService class:
private void purchaseStateChanged(int startId, String signedData,
String signature) {
ArrayList<Security.VerifiedPurchase> purchases;
purchases = Security.verifyPurchase(signedData, signature);
if (purchases == null) {
return;
}
ArrayList<String> notifyList = new ArrayList<String>();
for (VerifiedPurchase vp : purchases) {
if (vp.notificationId != null) {
notifyList.add(vp.notificationId);
}
ResponseHandler.purchaseResponse(this, vp.purchaseState,
vp.productId, vp.orderId, vp.purchaseTime,
vp.developerPayload);
}
if (!notifyList.isEmpty()) {
String[] notifyIds = notifyList.toArray(new String[notifyList
.size()]);
confirmNotifications(startId, notifyIds);
}
}
Follow this:
confirmTransaction(new String[] { latestPurchase.notificationId });
here and do this:
protected static void confirmTransaction(String[] notifyIds) {
if (amIDead()) {
return;
}
// there isn't a notifyid then this was the restore transaction call and this should be skipped
if (notifyIds[0] != null){
Log.i(TAG, "confirmTransaction()");
Bundle request = makeRequestBundle("CONFIRM_NOTIFICATIONS");
......
......
}
Works like a charm form me.. Thanks Guys...
