What is the "Verifying XXX.app" dialog and how do I get passed it?

Question

I'm trying to open a new app that I downloaded on OS X Yosemite 10.10.  Specifically, it is Android Studio.app version 0.8.13.

When I open it, I see the following dialog "Verifying Android Studio.app...":

The progress bar has been at 100% for about 10 minutes and it hasn't gone away.  Granted, this app is rather large at about 25gb of SDK that needs to be included in the directory.

How do I get passed this dialog?

One option to close stuck verification dialogs is to select CoreServicesUIAgent in the Activity Monitor's list of processes and kill it.
Or type in Terminal
 killall CoreServicesUIAgent

Just wait longer for the verification process to complete.

I had a similar situation with a 300 mb .app file.  I would get [Verifying "name_of_app.app"...], the percentage bar would be at 100% and it would hang for minutes.  I assumed there was a problem and came across your question while looking for an answer.  In the end I just left my MBP (mid-2010) alone for a few hours, came back and it was done verifying.  I recreated the conditions again and roughly timed it.  For a 300 mb .app file it took about 20 min to completely verify.

I was tempted to disable the verification using the process described here but waiting it out worked in this case.

Happy waiting.

The answer seemed to be to move the very large SDK out of the /Applications/Android Studio.app directory, then launch Android Studio, quit Android Studio, and move the sdk directory back into the /Applications/Android Studio.app directory.

After doing that, the Android Studio app launched fine.
