/**
 * Represents the status of in-app-purchase goods, this class provides information
 * about products purchased by a user as well as the ability to purchase additional
 * products. There are generally two types of payment systems: Manual and managed.
 * In manual payments we pay a specific amount in a specific currency  while with managed
 * payment systems we work against a product catalog defined in the server.
 * 

In-app-purchase API's rely on managed server based products, other payment systems * use the manual approach. An application dealing with virtual goods must support both * since not all devices feature in-app-purchase API's. An application dealing with physical * goods & services must use the latter according to the TOS of current in-app-purchase * solutions. * * @author Shai Almog */ public abstract class Purchase { private static ReceiptStore receiptStore; private static final String RECEIPTS_KEY="CN1SubscriptionsData.dat"; private static final String RECEIPTS_REFRESH_TIME_KEY="CN1SubscriptionsDataRefreshTime.dat"; private static final String PENDING_PURCHASE_KEY = "PendingPurchases.dat"; private static List receipts; private static Date receiptsRefreshTime; /** * Installs a given receipt store to handle receipt management * @param store */ public final void setReceiptStore(ReceiptStore store) { receiptStore = store; } protected final ReceiptStore getReceiptStore() { return receiptStore; } /** * Gets all of the receipts for this app. Note: You should periodically * reload the receipts from the server to make sure that the user * hasn't canceled a receipt or renewed one. * @return List of receipts for purchases this app. */ public final List getReceipts() { synchronized (RECEIPTS_KEY) { if (receipts == null) { if (Storage.getInstance().exists(RECEIPTS_KEY)) { Receipt.registerExternalizable(); try { receipts = (List)Storage.getInstance().readObject(RECEIPTS_KEY); } catch (Exception ex) { Log.p("Failed to load receipts from "+RECEIPTS_KEY); Log.e(ex); receipts = new ArrayList(); } } else { receipts = new ArrayList(); } } return receipts; } } /** * Gets all of the receipts for the specified skus. * @param skus The skus for which to get receipts. * @return All receipts for the given skus. */ public final Receipt[] getReceipts(String... skus) { List out = new ArrayList(); List lSkus = Arrays.asList(skus); for (Receipt r : getReceipts()) { if (lSkus.contains(r.getSku())) { out.add(r); } } return out.toArray(new Receipt[out.size()]); } /** * Gets the time that receipts were last refreshed. * @return */ private Date getReceiptsRefreshTime() { synchronized(RECEIPTS_KEY){ if(receiptsRefreshTime == null) { if (Storage.getInstance().exists(RECEIPTS_REFRESH_TIME_KEY)) { receiptsRefreshTime = (Date)Storage.getInstance().readObject(RECEIPTS_REFRESH_TIME_KEY); } else { return new Date(-1l); } } return receiptsRefreshTime; } } /** * Sets the list of receipts. * @param data */ private void setReceipts(List data) { synchronized(RECEIPTS_KEY) { receipts = new ArrayList(); receipts.addAll(data); Storage.getInstance().writeObject(RECEIPTS_KEY, receipts); } } /** * Updates the last refresh time for receipts. * @param time */ private void setReceiptsRefreshTime(Date time) { synchronized(RECEIPTS_KEY) { receiptsRefreshTime = time; Storage.getInstance().writeObject(RECEIPTS_REFRESH_TIME_KEY, receiptsRefreshTime); } } /** * Indicates whether the purchasing platform supports manual payments which * are just payments of a specific amount of money. * * @return true if manual payments are supported */ public boolean isManualPaymentSupported() { return false; } /** * Indicates whether the purchasing platform supports managed payments which * work by picking products that are handled by the servers/OS of the platform vendor. * * @return true if managed payments are supported */ public boolean isManagedPaymentSupported() { return false; } /** * Performs payment of a specific amount based on the manual payment API, notice that * this doesn't use the in-app-purchase functionality of the device!
