        public Set<String> wordDictAvail (String inword){
            Set<String> set = new HashSet<String>();
            int wa = 0;
                 int dictWordLn;

                     String currChar;
                int i = 1;
                     dictWord = scanner.nextLine().trim();
            dictWordLn = dictWord.length();
                for (int a = 0; a <= dictWordLn-1 ; a++){
                    currChar = Character.toString(dictWord.charAt(a));
                    if (inword.contains(currChar)){
                        i =i*1;
                                     } else {i=i*2;}
                    }
                if (i==1){
                    set.add(dictWord);
                                     wa++;
                                     }

in your MainActivity or any class which extends from Activity declare a static Context

private static Context con;

Assign in onCreate()

con = MainActivity.this;

From any other Activity reference this context like

Context presentContext = MainActivity.con

Let me know if that helps.
