title: How could i get the correct external storage on Samsung and all other devices?
body: <p>The official method Environment.getExternalStorageDirectory() seems to be not working on Samsung devices... </p>
  
  <p>It return "/sdcard/" but not the real path "/sdcard/external_sd/", you could refer to the following post</p>
  
  <p><a href="https://stackoverflow.com/questions/4210154/android-sd-card-characteristics-on-samsung-galaxy">Android SD Card Characteristics on Samsung Galaxy</a></p>
  
  <p>Is there another methods to detect the external real storage path and suitable for all devices ?? or just teach me how to avoid this issue ??</p>
  
  <p>Thanks.</p>
