Android Question problem with sales in google play

fanfalveto · Aug 4, 2014

Over 90% of sales are being canceled once made the charge and the downloaded application.
This makes me suspect that you download is copied and then vanishes.
Any ideas to try to fix this?
Thank you

Hi, I don't think anybody can copy an apk from the play store..
and if a sale is cancelled then google will remotely un-install the app from the device.

fanfalveto · Aug 4, 2014

not from google, but if i download an app can i make a copy then cancel the payment and after install again?
I don´t know

NJDude · Aug 4, 2014

Yes, that can be easily done on a rooted device.

fanfalveto · Aug 4, 2014

ok, the app if better for rooted devices.
it is strange that so many purchases canceled.
finally, patience
i must think for a solution but is difficult to avoid copying
thank you

NJDude · Aug 4, 2014

There's always a way around, so, whatever solution will not be 100% secure.

If you can check to be sure that the cancellation was not due to the credit card being denied.

I had a block of sales canceled because the person seemed to be using an invalid credit card. I'm not sure if the person ever got to download the app.

yes i see that,there are some for a bad credit card, but a lot of canceled by user after download.
i write to google and they says there are 15 minutes after the payment where the buyer can cancel the purchase.
is a problem but complicated to resolve because i think is impossible to identify who paid and who did not.
is possible to know who is using the app, but not who pay.

Did you integrate the Google License Library in your app? If so, then the app wouldn't work after payment cancelling without cracking it.

I'm not that far to sell an app, but...

If your app IS sold, what kind of information do you get? Mailaddress of the buyer?

No, i will read about this.
Thank you

Read here and here.

I believe the cancellation time has now been extended to 2 hours as of today...

fanfalveto · Aug 4, 2014

Thank you very much

This is hazardous...
Then one solution will be to request a key that can only be obtained by email from developer (after a purchase is made)
in your app you will need to embed a unique identifier for each copy during compilation. Your user must provide you with that identifier. Still they may crack it, but the
way you design the identifier will define the degree of difficulty for the hacker.
The point is: from the time the download is complete, to the time the user receives your key, the two hours will pass. during this time
you can let your user to test the app with limited functionality.

fanfalveto · Aug 5, 2014

This is a solution, but in this case i can´t do that.
Thank you

fanfalveto · Aug 5, 2014

Is not the same

The point is: from the time the download is complete, to the time the user receives your key, the two hours will pass. during this time
you can let your user to test the app with limited functionality.

but i do that:
1-the program starts and runs one time
2-the service is runing and listening. if receive and sms with a keyword (I give this key by email after payment confirmation) the program can run without restrictions anymore.
then they can see the program runs fine (the first time) and i can take a beer

And why not using tools already exist and work (see my post #9)?

fanfalveto · Aug 5, 2014

Sorry, i will, and thank you
this is an idea i have.

This makes no sense at all. If you are going to manage the purchases, why are you going to share profits with google? If you want to put a limited app to activate it with email and a key, put it free on the app store and use paypal to accept payments.

If you want google do all the job, simply use the Licensing library
