Can't open apk file on Android 4.3

Question

I build an apk file with Eclipse and I can normally install it on Android 2.3.7, but on 4.3 I cant open apk file and I just get statement "cant open this file". What should I do?

Answer 1

by default in Android Devices if you try to install an .apk file via OTA installation you will have the message " cant open this file ".

try this options:

• in you android device: Settings > Security > Unknown sources , check to allow installation of apps from sources other than the Play Store

• Sometimes you must delete an installed version, it could be signed with a different Keystore .
