Re: sideload apks in gionee elife e7 mini
Welcome to Android Central! Are you unable to install the apps using a legitimate app store like Google Play Store, Amazon Appstore, GetJar, or SlideMe?
Installing apks must be done with caution, because many sources of apk downloads may also be sources of malware. On top of that, many of those apks are probably pirated, which we strongly discourage.
For legitimate apk files, you have to make sure "Unknown Sources" is checked on in Settings>Security.
