Can't install 3rd party application on android.

[sonam7954]

I am trying to install apk file to my android mobile, I have enable unknown resource option under the settings.

But still i am getting this error "Application can not install"

What reason could be for this ??

PS: I have updated android from KitKat to lollipop few days back.

Same problem here cant install in my Samsung Note 2 "app not installed" :/ but in my local brand android made by my country I can install anything 3rd party apps. I think it is the certificate of the app it is the same in s60 Nokia before, I watched a clip from youtube about this and you gonna need zipsigner but my problem is I dont know how to get my keystore :/

Google play service must be blocking from installing app check app verification setting under google play service aka google GMS service. Also make sure that app verification is disabled under developer option.

/ You should change your settings for app installation and allow Third party installation. Its unchecked by default on all devices.
