How to read a folder in the assets directory and read files from it in android?

File reading is important in android. For the put the files in the assets folder.

We can able to read

• foldername
• filename
• Contents of the file

First we read the name of the folder.

private String folder_array[];
AssetManager mngr_spinner = getAssets();
try
{
         //"air" is the name of the folder...
	folder_array= mngr_spinner.list("air");
}
catch (IOException e1)
{
	e1.printStackTrace();
}

“folder_array” contains all the names of the folder
Then if the path is set to

folder_array= mngr_spinner.list("air/Buttons Events");

Then the list of file name is got.
If you want to read the file content then do the following..

InputStream is;
try
{
	is = getAssets().open(air/Buttons Events/filename);
	int siz = is.available();
	byte[] buffer = new byte[siz];
	is.read(buffer);
        //This text contains the content of the file..
	String text = new String(buffer);
        is.close();
}
catch (Exception e)
{
	 Toast.makeText(CheatSheet.this,"File Not Found Error.Please ensure that file is not deleted.", Toast.LENGTH_SHORT).show();
}
