Not sure, but perhaps is it something with your proguard setup? Sample app works just fine using maven central dependency

@max-critcrew the community here would appreciate if you can provide a patch/PR for this issue

@kal27 seem like we need to add a check for `isInitialized()` at the beginning of this method. Do you want to contribute with a PR?

@jangrewe if you refer to #376 -I would recommend you to link your project with a master branch of this repo.

just checked it using **this** library from the maven central and it works just fine

@henriquegemignani can you please add a README section describing the purpose of this? Other then this it looks good to me

@henriquegemignani are you still interested in this? Just wanted to poke you about missing documentation here

@max-critcrew can you please clean up all the extra changes in the PR? (anything except `BillingProcessor` changes?) Also do ming explaining what error codes will 'double'?

@max-critcrew this project is published via maven central, so these extra changes are not required. Also the licence key in the sample project does not really needs to be changed...

Was it error 110 maybe? I found that `onProductPurchased` wasn't invoked on the main thread, and thus if you tried to update views in your `onProductPurchased` - it would crash...
