Android App installs and runs fine on development phone but gives "Unfortunately app has stopped" on google play

Question

ok so my app installs and runs fine on an android phone during development when I connect it through usb. But when I deployed to production, now it gives me "Unfortunately app has stopped" every time I open the app.

I have tried suggestions from others where I cleared up the data and cache but not those buttons were disabled for me. seems like there was no cache or data to clear.

how can I find out whats causing the issue? has anyone had this problem before?

NEW UPDATE:

so I commented out the 
proguard.cfg as shown in the project.properties and then it worked.  
so there is something wrong in the proguard.cfg 
Can some one see if there is anything obvisous please? 
I am using exactly what urban airship suggested on their sample proguard.cfg

Appreciate all your helps

Answer 1

It sounds like your configuration is invalid from another question (Urban Airship crashes at take off. Illegal Argument Exception) it would lead me to think you need to check that your key and secret key are correct.

from the docs:

airshipconfig.properties

gcmSender = Your Google API Project Number (allows multiple senders separated by commas)
transport = gcm
developmentAppKey = Your Development App Key
developmentAppSecret = Your Development App Secret
productionAppKey = Your Production App Key
productionAppSecret = Your Production App Secret
inProduction = false

Make sure your productionAppKey and productionAppSecret are correct (and probably not the same as your development ones)

Answer 2

I think your ProGuard setup could be tripping up the library you're using. See here for how to set up your ProGuard for Urban Airship. Notably, you probably want to add at least this to your Proguard config:

# Required if you are using the airshipconfig.properties file                                       
-keepclasseswithmembers public class * extends com.urbanairship.Options {
    public *;
}

Or you haven't set up keys correctly, like in the other answer.

In the future, if you're using ProGuard, (and you should be), you need to test the deployed APK before uploading to Google Play.
