Android Android Data Persistence File Storage Reading from Internal Storage

Could someone explain to me what I just wrote?

Hello.

I am having trouble understanding what I wrote down as I followed this video, could someone please explain this?:

public static void saveAssetImage(Context context, String assetName) {
        File fileDirectory = context.getFilesDir();
        File fileToWrite = new File(fileDirectory, assetName);

        AssetManager assetManager = context.getAssets();
        try {
            InputStream in = assetManager.open(assetName);
            FileOutputStream out = new FileOutputStream(fileToWrite);

            in.close();
            out.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

Hmm, maybe I should have finished the beginner Android track...

Please help!

You can use this function to save files from assets folder to the internal storage of you applications. Inline description:

public static void saveAssetImage(Context context, String assetName) {
     // get the internal storage folder
     File fileDirectory = context.getFilesDir();

     // get file in the internal storage folder with name = assetName 
     File fileToWrite = new File(fileDirectory, assetName);

     // get assets manager to access assets files 
     AssetManager assetManager = context.getAssets();
     try {
          // open input stream to read from the assets file
          InputStream in = assetManager.open(assetName);

          // open output stream to write to the internal storage file
          FileOutputStream out = new FileOutputStream(fileToWrite);

          // missing copy function from inputStream to outputStream
          /* copyFile(inputStream, outputStream); */

          // close the streams after finish copying
          in.close();
          out.close();
     } catch (IOException e) {
          e.printStackTrace();
     }
}

Thanks! I think I'll finish the beginner track before I continue the intermediate track though :).

I finished the Beginner Track and this didn't make sense to me at all

I would recommend doing their java course before this. I only knew what this mean due to prior C# knowledge from college but he definitely does not explain what he is doing very well if you have no clue about these terms.
