Field Summary

private java.lang.String	bindir
private Context	context
private boolean	forceRestart If the second parameter sent to new NmapInstall(Context, String) is "restart" then NmapInstall will send a message to NmapMain.handler telling it to restart the app after install completes.
private Resources	resources Once you have the application Context, use that to establish a Resources object that can be used to open the R.raw.* files.

Method Detail

createNewFileAndDeleteExisting

private void createNewFileAndDeleteExisting(java.lang.String path)

Simple method for deleting a file if it does not exist. Note there could be a bug here - if the expected behavior was to /create/ the file, then this is always creating a file, then deleting it. Seems a little backward.

Parameters:

path -

onPostExecute

protected void onPostExecute(java.lang.Void myVoid)
