Your android debug keystore file is missing [FIX]

 

There must be some other ways to solve this error. But how i solved is simply adding this line of code in FacebookAndroidUtil.cs file

System.Environment.GetEnvironmentVariable("G:\android\android-sdks") + @"\.android\debug.keystore" : 

 
The problem was i had %HOMEPATH% environment variable in other drive(In G:/) and unity project in another drive.
Then whenever Facebook SDK calls System.IO.File.Exists(DebugKeyStorePath), DebugKeyStorePath is actually wrong. That is because DebugKeyStorePath is searching in

System.Environment.GetEnvironmentVariable("HOMEPATH") + @"\.android\debug.keystore"

Which is wrong path to find the key.

Solution

Go to FacebookAndroidUtil.cs file, and on line 62 change the code from

System.Environment.GetEnvironmentVariable("HOMEPATH") + @"\.android\debug.keystore" : 

To

System.Environment.GetEnvironmentVariable("G:\android\android-sdks") + System.Environment.GetEnvironmentVariable("G:\android\android-sdks") + @"\.android\debug.keystore" :
Change G:\android\android-sdks to you android sdk path.

Now its working fine and i got my keyhash in Facebook settings. I hope this will work for you too.
