I have Sony Xperia ZL running 4.2.2 and rooted.

I want to run the new version of the email app that Sony ships with Z1. I have the semcemail.apk and know how to get it into the systems/apps directory via root explorer, however it will not run. When I overwrite the file of the oem version of the same name, and change permissions to rw-r-r it just continues to give me mail service stopped errors. When I replace the oem version I am able to run again. Am I missing something or just not compatible? The Z1 runs same 4.2.2 and the apk seems to be just a version variant up from the 4.2 client I am running.

Thanks
