Just in case somebody is looking for this info.... If you want to install an apk which you also programmatically downloaded and stored in your private "files" folder (ie. "/data/data/com.yourapp.name/files"), you need to get the uri for the full path by first using getFileStreamPath as follows:

File fullPath = getFileStreamPath("name_of_downloaded_app.apk");

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(fullPath), "application/vnd.android.package-archive");
startActivity(intent);

Hope this helps...

See if this can help: install Apk via Intent. Not sure if this is the way to go though.
