What steps will reproduce the problem?
1. Compile and run Rev 78 
2. Click to "PORT CONFIG"

NullPointerException, the app closes.

What version of the product are you using? On what operating system?

Please provide any additional information below.

The NullPointer Exception happens at    mApp.setSerialPortConfigSelections. It 
looks like the HashTables are not filled correctly, due to wrong string 
comparisons (== instead of .equals()).

The wrong string comparisons happen for example here:

//stop bits hashmap
        for(String str: stop_bits_list){
            if(str == "1"){
                mStopBitsHashMap.put(str, FTDI_Constants.STOP_BITS_1);
            }else if(str == "1.5"){
                mStopBitsHashMap.put(str, FTDI_Constants.STOP_BITS_15);
            }else if(str == "2"){
                mStopBitsHashMap.put(str, FTDI_Constants.STOP_BITS_2);
            }
        }

Indeed, changing all '==' to equals() solves this problem.
