Strangely my developed apps are crashing

Currently I have uploaded new updated version of an app to google play store and strangely it crashing. Even I could not able to read the message and perhaps it says “unfortunately stopped …” I really dont know what is the error message.

Before uploading the app to google play store, I used a lot on my mobile phone device and it ran very smooth. Then I added two kind of ads, unity ads and admob ads and uploaded to google play store. But just now re-downloaded the developed app from google play store and it is crashing just few moments later only. I am bit worried about my developed rest of the apps.

I am totally blind and have no clue what should I do to figure out the real reason. if any one has encountered such issue please guide me to proceed further.

App crashing isn’t something we’ll be able to figure out just from that bit of info. Good news is, you might be able to get that info on why. Run logcat on your device while running the app and once it crashes, you can post your logcat in the android part of Unity forums and see if they can help you go over it if you can’t figure out the info yourself.

Oh thanks for the response. Actually I am bit new to unity and programming thing. I love this world. My apology, but what is logcat and how could I run this on mobile device??

Are you on a windows computer that you use to develop from?

Here is the link I used to learn how to do a logcat. At work now, so can’t go into to much detail, but if you don’t understand it, then ask and I’ll try to help when I can.
