<h3 id="upgrade-getBuyIntentToReplaceSkus">The getBuyIntentToReplaceSkus()

  method</h3>

<p>This method is used to upgrade or downgrade a subscription purchase. The method

is similar to <a href="#getBuyIntent"><code>getBuyIntent()</code></a>, except

that it takes a list of already-purchased SKUs that are to be

replaced with the SKU being purchased. When the user completes the purchase,

Google Play cancels the old SKUs and credits the user with the unused value of

their subscription time on a pro-rated basis. Google Play applies this credit

to the new subscription, and does not begin billing the user for the new

subscription until after the credit is used up.</p>

<p>This method was added with version 5 of the in-app billing API. To verify

that the method is reported, send an <code>isBillingSupported</code> AIDL

request.</p>

<p class="note"><strong>Note:</strong> You can only use this method for

subscription purchases. If the passed <code>type</code> parameter is anything

other than <code>"subs"</code>, the method returns

<a href="#billing-codes"><code>BILLING_RESPONSE_RESULT_DEVELOPER_ERROR</code></a>.

Furthermore, the passed SKUs may not include SKUs for seasonal

subscriptions.</p>

<p>

  This method returns a response code integer mapped to the {@code

  RESPONSE_CODE} key, and a {@link android.app.PendingIntent} to launch the

  purchase flow for the in-app subscription mapped to the {@code BUY_INTENT}

    <li>Users purchase your subscriptions from inside your apps, rather than

    <li>Users can renew their subscriptions while a current subscription is

    <li>Users can upgrade or downgrade a subscription in the middle of a

billing errors that may occur. Your backend servers can use the server-side API 

to query and update your records and follow up with customers directly, if needed.</p>

<h3 id="manual-renewal">Manual Renewal</h3>

<p>With version 5 of the In-app Billing API, users can renew a subscription

during its active period even if the subscription is not set to

automatically renew. If the user purchases a subscription while the subscription

is active, it is extended by the appropriate period at the current rate.</p>

<p>For example, Achilles has a subscription to the <em>Modern Hoplite</em> app.

His subscription is currently due to expire on August 1. On July 10, he

purchases a 3-month subscription at the current rate. Those three months are

added to his existing subscription, so the subscription now expires on November

1.</p>

<p>It is up to the app to convey this with an appropriate UI. For example, if a

user does not have an active subscription, the app might have a

<strong>buy</strong> button, but if the user has a subscription the button might

say <strong>renew</strong>.</p>

<h3 id="upgrade">Subscription Upgrade/Downgrade</h3>

<p>

  With version 5 of the In-app Billing API, users can upgrade or downgrade a

  subscription during its active period. When the user does this, the active

  subscription is canceled and a new subscription is created. The unused

  balance of the old subscription is applied on a pro-rated basis to the new

  subscription. The first billing period for the new subscription begins after

  that balance is used up. (The new subscription does not need to have a period

  of the same length as the old one.)

</p>

<p>For example, Samwise has a subscription to online content from the

<em>Country Gardener</em> app. He currently has a monthly subscription to the

Tier 1

version of the content (which has text-only content). This subscription costs

him £2/month, and renews on the first of the month. On April

15, he chooses to upgrade to the Tier 2 subscription (which includes video

updates), costing £3/month. His Tier 1 subscription is immediately ended.

Since he paid for a full month (April 1-30), but only used half of it, half of a

month's subscription (£1) is applied to his new subscription. However, since

that new subscription costs £3/month, the £1 credit balance only pays for ten

days. So Samwise's credit pays for his subscription from April 15-25. On April

26, he is charged £3 for his new subscription, and another £3 on the 26th of

each month following.</p>

<p class="note">

  <strong>Note:</strong> The new subscription's billing date depends on when

  the subscriber's pro-rated credit runs out, so the subscriber cannot upgrade

  or downgrade to a seasonal subscription, which has fixed and predetermined

  beginning and end dates.

</p>

<p>When a user upgrades or downgrades a subscription, your app calls

<a href="{@docRoot}google/play/billing/billing_reference.html#upgrade-getBuyIntentToReplaceSkus">

<code>getBuyIntentToReplaceSkus()</code></a>.

This method is passed the new SKU the user wants to buy, and all

the old SKUs that are superseded by it. The remaining portions of the old SKUs

are used to pay for the new subscription, and billing begins when this credit

is used up.</p>

<h3 id="deferred-billing">Deferred Billing</h3>

<p>Using the

<p>When the user cancels a subscription, Google Play does not offer a refund for

the current billing cycle. Instead, it allows the user to have access to the

cancelled subscription until the end of the current billing cycle, at which time

canceled subscription until the end of the current billing cycle, at which time

it terminates the subscription. For example, if a user purchases a monthly

subscription and cancels it on the 15th day of the cycle, Google Play will

consider the subscription valid until the end of the 30th day (or other day,

<p>If you receive requests for refunds, you can use the

resulting charges to the user, and </li>

users purchase your in-app products without any resulting charges to the user.

Test purchases can be used in alpha/beta releases or in published apps. </li>

<li><strong>Real purchases</strong>, which let regular users make real purchases

of your in-app products with actual charges to the user’s payment instruments.

In this case, you can use Google Play’s alpha and beta release groups to manage

<p>Test purchases offer a secure, convenient way to enable larger-scale testing

<p>Once authorized for testing access, those users can make purchases without

Test purchases are real orders and Google Play processes them in the same way as

other orders. When purchases are complete, Google Play prevents the orders from

going to financial processing, ensuring that there are no actual charges to user

accounts, and automatically canceling the completed orders after 14 days. </p>
