title: Accessing the SD-Card in an Android Application
body: <p>I am currently developing an Android Application, that will open and save .txt files.
  In order to make it easy to read external .txt files i want to make sure, that they are saved in the app's folder on the SD-Card.
  Unfortunately i am only able to access /storage/emulated/0.</p>
  
  <p>I already tried 2 different possibilites:</p>
  
  <pre><code>Environment.getExternalStorageDirectory()
  getExternalFilesDir("MyFileStorage")
  </code></pre>
  
  <p>They both lead to /storage/emulated/0 on the internal storage.
  Does anyone know how i can access the app's folder on the SD Card of my Smartphone (USB-Debugging).</p>
