Ich denke, Sie haben einen Tippfehler während Paketnamen Intent Einstellung. Es sollte "application/vnd.android.pa ck alters Archiv" sein. So ist die ganze Linie wäre:

webIntent.setDataAndType(Uri.fromFile(apkFile), "application/vnd.android.package-archive"); 

Das ist, warum Sie ActivityNotFoundException bekommen, weil du falsches Paket geben, und die richtigen Activity nicht gefunden werden kann.
