Android, to save into internal Storage -

i'm testing on divice, false in line

boolean issdpresent = android.os.environment.getexternalstoragestate().equals(android.os.environment.media_mounted); 

so, don't have external storage in device, correct?, how can save image on internal storage? if put line...

fileoutputstream fos = context.openfileoutput(filename, context.mode_private); 

the class complete

public class imagestorage {  public static string savefile(bitmap bitmap, string filename) {         try {         fileoutputstream out = context.openfileoutput(filename, context.mode_private);         bitmap.compress(bitmap.compressformat.jpeg, 90, out);         out.flush();         out.close();     } catch (exception e) {         e.printstacktrace();     }     }   public static file getimage(string imagename) {      file mediaimage = null;     try {         string root = environment.getexternalstoragedirectory().tostring();         file mydir = new file(root);         if (!mydir.exists())             return null;          mediaimage = new file(mydir.getpath() + "/images/"+imagename);     } catch (exception e) {         // todo auto-generated catch block         e.printstacktrace();     }     return mediaimage; }  public static boolean checkifimageexists(string imagename) {     bitmap b = null ;     file file = imagestorage.getimage("/"+imagename+".jpg");     string path = file.getabsolutepath();      if (path != null)         b = bitmapfactory.decodefile(path);       if(b == null ||  b.equals(""))     {         return false ;     }     return true ; } 

}

the word "context" it's marked "cannot resolved". have spent 1 week issue, please me

because class not default has access context, need pass in method (see how added context parameter):

public static string savefile(context context, bitmap bitmap, string filename) {} 

so when call it, need pass kind of context. if call activity, can use this.
