I don't know very much about programming, so I have produced a rather crappy implementation of the stroke input method.

In particular, I load all the stroke data into memory when the input method service is instantiated:

It works, but the downsides are:

• It takes a long time to load on lower-end devices (e.g. takes 1.2 seconds on my cheap phone with ~1.3 GB RAM)
• It requires a lot of memory

1. Most of the time is spent duringloadSequenceCharactersDataIntoMap. Is there a better way of reading a TSV than what I currently have?

   Lines 220 to 252 inc23d584

   	@SuppressWarnings("SameParameterValue")
   	privatevoidloadSequenceCharactersDataIntoMap(
   	finalStringsequenceCharactersFileName,
   	finalMap<String,String>charactersFromStrokeDigitSequence
   	)
   	{
   	finallongstartMilliseconds =System.currentTimeMillis();
   	try
   	{
   	finalInputStreaminputStream =getAssets().open(sequenceCharactersFileName);
   	finalBufferedReaderbufferedReader =newBufferedReader(newInputStreamReader(inputStream));
   	Stringline;
   	while ((line =bufferedReader.readLine()) !=null)
   	{
   	if (!isCommentLine(line))
   	{
   	finalString[]sunderedLineArray =Stringy.sunder(line,"\t");
   	finalStringstrokeDigitSequence =sunderedLineArray[0];
   	finalStringcharacters =sunderedLineArray[1];
   	charactersFromStrokeDigitSequence.put(strokeDigitSequence,characters);
   	}
   	}
   	}
   	catch (IOExceptionexception)
   	{
   	exception.printStackTrace();
   	}
   	finallongendMilliseconds =System.currentTimeMillis();
   	sendLoadingTimeLog(sequenceCharactersFileName,startMilliseconds,endMilliseconds);
   	}

2. Alternatively, given that the stroke data is a constant map, is it possible to bake it into the class so that I don't need to load it every time? Or, can we do something completely different that isn't so memory intensive?
