How to call a method with Context context

Question

Hello i found this method that creates a file and add strings in it

public void generateNoteOnSD(Context context, String sFileName, String sBody) {
try {
    File root = new File(Environment.getExternalStorageDirectory(), "Notes");
    if (!root.exists()) {
        root.mkdirs();
    }
    File gpxfile = new File(root, sFileName);
    FileWriter writer = new FileWriter(gpxfile);
    writer.append(sBody);
    writer.flush();
    writer.close();
    Toast.makeText(context, "Saved", Toast.LENGTH_SHORT).show();
} catch (IOException e) {
    e.printStackTrace();
}
}

My question is how to call this method ? i tried something like this

 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    String FILENAME = "hello_file";
    String string = "hello world!";
    generateNoteOnSD(Context ,FILENAME,string);
}

I don't understand the Context context part

call method like this generateNoteOnSD(this ,FILENAME,string); — Shivam Sharma, May 30 '17 at 12:57

you need to call the getApplicationContext() if you are in an Activity

generateNoteOnSD(getApplicationContext(),FILENAME,string);

If your using Fragment then do like this

if it is Activity do like this

generateNoteOnSD(YourActivityName.this,FILENAME,string);
