i just found the solution. In my case,
i just upgrade my Linux from 32 to 64 bit
And reinstalled studio. the The cause of this problem was-AAPT2 in >3.1 versions will only be executable in 64 bit OS and also
the android Studio just removed the support of 32 bit Linux from in its updated versions
I think this will be help full to some one who has the same problem while building the project to apk file and hope you guys will help me to improve this answer,edits are invited. Thank you in advance
