In my android application I an storing an image file in internal memory using below code-
FileOutputStream fos = con.openFileOutput(fileName, con.MODE_PRIVAT
Try this:
ImageView imageView = (ImageView) findViewById(R.id.image);
File filePath = getFileStreamPath(fileName);
imageView.setImageDrawable(Drawable.createFromPath(filePath.toString()));
In the above snippet R.id.image is id of ImageView somewhere in your layout. fileName is a String containing name of the file you used in openFileOutput call.
