Why is my apk file not installed even though it says it is?

[Android Central Question]

When I opened an apk file in my downloads and installed it, it said 'application installed' but I could not open the app or find it in my apps area so I don't think it actually was installed. Please help if you know something about this.

Welcome to Android Central! What apk is it, and where did you download it from? You need to be careful with apk files, since the sites where people find them are not always the most upstanding. They can be good places to get malware.
