Android的 - 如何检查是否在应用程序内购买已经完成？ [英] Android - how to check if in app purchase has already been done?

问题描述

我要如何检查是否在应用程序内购买之前已经做了什么？
所以，我的用户不必在卸载并重新安装应用程序，以购回本在应用程序内购买？

How do i check if a in app purchase has been done before? So that my user doesnt need to repurchase the in app purchase upon uninstalling and reinstalling the app?

我已将我的应用程序项目在Android市场上易于管理发布页面。

I have set my in app item to managable in the android market publish page.

我看了一下 RESTORE_TRANSACTION ，但我不知道我需要寻找这里面的反应，以及如何对此进行测试。

i have read about RESTORE_TRANSACTION but I do not know what i need to look for inside this response and also how to test this.

任何帮助将大大AP preaciated。

Any help would be greatly appreaciated.

推荐答案

您需要恢复交易，你使用上面指定的RESTORE_TRANSACTION标志。您应该只这样做一次，当应用程序首次启动时间，或者如果用户清除数据。

You need to restore the transactions, using the RESTORE_TRANSACTION flag you specified above. You should only do this once, when the application starts for the first time or if the user clears the data.

我会建议为你自己这个过程更简单，你寻找到<一个href=\"https://github.com/robotmedia/AndroidBillingLibrary/blob/master/DungeonsRedux/src/net/robotmedia/billing/example/Dungeons.java\"相对=nofollow> AndroidBillingLibrary ，它允许你在一个简单得多的方式与Android的界面应用内结算。

I would advice to make this process simpler for yourself, you looking into the AndroidBillingLibrary, which allows you to interface with the Android In App Billing in a much simpler manner.

下面是对事务如何恢复一个片段：

Here is a snippet of how the transactions are restored:

private void restoreTransactions() {
    if (!mBillingObserver.isTransactionsRestored()) {
        BillingController.restoreTransactions(this);
        Toast.makeText(this, R.string.restoring_transactions, Toast.LENGTH_LONG).show();
    }
}
