Hey ppl,
I have developed a paid product to a client. Now he want to transform the app in an InApp Non-Consumable.
The user will download for free, and pay to open the whole content.
How can i discover who has already buy the product? in order to show the whole content of the App without the need to purchase again. [import]uid: 79152 topic_id: 37068 reply_id: 67068[/import]
You can’t check who already bought the product, so making it free, you risk bad reviews from people who actually paid for it. [import]uid: 50459 topic_id: 37068 reply_id: 145293[/import]
There is still potentially a workaround that would enable you to resolve this.
Does your current app save any files to the documents directory on the device? If so, you could do the following. Release an update to your app. In that update, your code would check whether some file you choose exists in the documents directory. If it does, you know that the app was already previously installed on the device (at the time when it was a paid app), and therefore you should unlock the content. If the file doesn’t exist, you know the app was just downloaded and run for the first time, in which case you would keep the content locked. In both cases, you would set a more permanent flag in a dedicated file to indicate whether the content should be locked or unlocked, so that you can check it on future runs and future updates without this workaround.
