Trying to display images from a specific folder in the Android hardware device

//posense is a directory in the Android hardware device and there are some pictures in the directory

    ImageView image1, image2;

    File imagedirectory;
    File[] imagepool;

    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        image1 = (ImageView)findViewById(R.id.imageView1);

        imagedirectory = new File("/posense"); 

        imagepool = imagedirectory.listFiles();

        image1.setImageResource(imagepool[1]); //this line is giving me an error

}

How can I solve this problem?

Try these lines instead of imagedirectory = new File("/posense");:

    String path = Environment.getExternalStorageDirectory().getName() + File.separatorChar + "posense";
    imagedirectory = new File(path);
    image1.setImageURI(Uri.fromFile(imagepool[1]));

Use this instead:

image1.setImageURI(Uri.fromFile(imagepool[1]));

Documentation to be found here: setImageURI and fromFile.

Also, be aware that imagepool[1] is the second element in the array, not the first.
