try {

String filename = "SampleFile.txt"; String filepath = "MyFileStorage";

                FileInputStream fis = new FileInputStream(myExternalFile);
                DataInputStream in = new DataInputStream(fis);
                BufferedReader br =
                        new BufferedReader(new InputStreamReader(in));
                String strLine;
                while ((strLine = br.readLine()) != null) {
                    myData = myData + strLine;
                }
                in.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
          inputText.setText(myData);
            response.setText("SampleFile.txt data retrieved from External Storage...");
        }
    });

    if (!isExternalStorageAvailable() || isExternalStorageReadOnly()) {
        saveButton.setEnabled(false);
    }
    else {
        myExternalFile = new File(getExternalFilesDir(filepath), filename);
    }
