Manually instaling apk Long story short: I don't have google services, and I accidentally deleted the backup. I can't install any apk no more via package installer. When I click "install" it just says "Application not installed." I tried everything in my settings.

Is there any way to install apk without package installer? Maybe manually extracting apk file and copying it to some folder somewhere and then making shortcut in launcher?

I have android 4.4.
Are you rooted? If you have root, you can use a ROOT browser and put the google services app manually in the /system/app folder then reboot. It SHOULD work. 

And when you say google services, do you mean "Google Play Services"?
