Re: [Aerogear-users] An app crash scenario after clicking on push notification

Summers, I'd like to thank you for all your important support. I'm gonna have a look at Cordova developer docs. Eventually I'll try to write you again if there are some specific question about the bug fix. Have a nice day and thanks again for everything.
