title: Save String to a specific folder on internal storage - Android
body: <p>I am basically trying to save a String to a specific folder I create on the internal storage of my phone when I click the button save. I am still a noob at these stuff therefore I do not know what to do. I want to access the file using the file manager and not through the application I created. 
  So I need help with:
  1- Create the folder.
  2- Save the string to that specific folder.
  Any help is appreciated and thank you in advance.</p>
  
  <pre><code>Save.setOnClickListener(new OnClickListener() {
              @Override
              public void onClick(View v) {
                  //Toast.makeText(getApplicationContext(), ("X values: "+mg1.getXs()) ,Toast.LENGTH_LONG).show();
                  //Toast.makeText(getApplicationContext(), SENSOR_READING_STRING ,Toast.LENGTH_LONG).show(); 
  
                  String filename = "Data.txt";
                  String ABCD_STRING = "SENSOR_READING_STRING";
                  FileOutputStream outputStream;
  
                  try {
                    outputStream = openFileOutput(filename, Context.MODE_PRIVATE);
                   outputStream.write(ABCD_STRING.getBytes());
                    outputStream.close();
                  } catch (Exception e) {
                    e.printStackTrace();
                  }
  
              }
          });
  </code></pre>
