Android: Difference between FileOutputStream and FileWriter

Question

I was wondering what the exact difference is between Android's FileOutputStream and FileWriter class. When would it be most appropriate to use each one?

Answer 1

If I remember correctly, FileOutputStream is more general purpose - it can be used for binary data or text data. FileWriter is used for text only.

FileWriter is meant for writing streams of characters. For writing streams of raw bytes, consider using a FileOutputStream.
