i guess have typo while setting package name intent. should "application/vnd.android.package-archive". whole line be:

webintent.setdataandtype(uri.fromfile(apkfile), "application/vnd.android.package-archive");

that's why got activitynotfoundexception, cause give wrong package, , proper activity can't found.
