Hi, yes I will consider in app purchase if that is the only option. So am I right to say some free and paid app actually release 2 versions which Google play see it as separate app and each app have their own data directory? On Saturday, 30 June 2012 23:34:56 UTC+8, RichardC wrote: > > Have you

I was also thinking to write a simple app that generate hash value and write it in a file, user will purchase this app and my main app will look for this file and compare the hash value. Will this work? Does Google allow this? On Sunday, 1 July 2012 00:02:54 UTC+8, Mystique wrote: > > Hi, yes I

I went with import/export in both versions, but the paid version allows you to email the export file also, for example. On Sat, Jun 30, 2012 at 12:41 PM, TreKing wrote: > On Sat, Jun 30, 2012 at 11:19 AM, Mystique wrote: > >> Right, I have import/export features but only available in the plan p

Hi, good to learn from all of you here. One of the usual request for the paid version is to remove ads and Internet permission. Some user just do no feel good about turning on Internet permission. If I implement in-app billing, the Internet permission will still be there since it already has it

Regarding the Internet permission - you don't have to use ads in the free version, rather offering the users some other incentive(s) to upgrade. 2012/7/1 Mystique > Hi, good to learn from all of you here. > > One of the usual request for the paid version is to remove ads and > Internet permissio

>> The idea of "irritate the user until he agrees to pay" just seems wrong to me. In my opinion, it is far better to let users opt out of ads for free than use advertising as some sort of black mail to push users into paying. In our app, only 2.7% of users choose to opt out of banners. The rest
