Can Linux apps be run in Android?

Question

Android is based on Linux; can native Linux applications be run on Android?

Answer 1

Android does not run X Windows, nor does it have many of the standard GNU libraries. So, since most native linux applications require one or both of these, most will not run.

In addition, even Java programs can be limited, because the version of Java that Android applications are written in is a subset of the standard Java library.
