mobile

I am new to this whole root process with phones.
I rooted my phone a few nights ago and it works perfectly.
However, i was looking into apps i should get and got highly interested in Xposed.
I downloaded the Xposed installer and the first thing i see on the home page is
"The latest version of Xposed is currently not active. Did you install the framework and reboot?"
After reading this, i clicked on Framework and got yet ANOTHER message in red saying
"Xposed is not (yet) compatible with android SDK version 21 or your processor architecture (aremabiv7a)."
then another
"CANNOT LINK EXECUTABLE: could not load library "libdvm.so" needed by "data/data/de.robv.android.xposed.installer/cache/app_process";caused by library "libdvm.so" not found

My device is "SM-N900T" and it had android 5.0 on it.
Am i basically out of luck with it?
I was really interested in customizing my device and getting a lot of things i did not want off of it.

Any help would be wonderful.
