Summary: In this lesson, we continue our discussion that we started in the previous video. After we talked about JSON data, we will discuss files. We will see how to create steams to read and write data. First, We will write some content to the file using FileOutputStream. Then, we will open the same file and read its content. The information is written to the text view. In both cases, we need to make sure that we are catching FileNotFoundException and IOException. When catching those exceptions, it is better to print the stack trace to know where something went wrong.
