code:

 String strSDCardPath = System.getenv("SECONDARY_STORAGE");  
 if ((strSDCardPath == null) || (strSDCardPath.length() == 0))   
  strSDCardPath = System.getenv("EXTERNAL_STORAGE");  
 System.out.println("strSDCardPath:" + strSDCardPath);  
 sdcardPath = strSDCardPath+ "/Android/data/" + context.getPackageName();;
