    <p>This is happening because you are placing the new image within the holder and calling invalidate to make it display but then you turn around and put the UI thread to sleep for 5 seconds so I cannot update it. By the time the system goes to update it, it is already moving on to the next image. I would use a AsyncTask to load the next Image in the background and then put a timer of 5 seconds in the the background thread before it updates the UI with the new data.</p> <p><strong>EDIT</strong><br> Here is the reworked version of your code that is operational if this is your exact code. If not you should be fine. (if the formatting is bad, it is because my work uses IE8 still and it doesn't let me see the formatting. I will fix when I get home.)</p> <pre><code>public class MyImageActivity extends Activity { private final String TAG = "MyImageActivity"; private ImageView mIV; @Override public void onCreate(Bundle savedInstanceState) { Log.e(TAG, "onCreate"); super.onCreate(savedInstanceState); setContentView(R.layout.mylayout); mIV = (ImageView) findViewById(R.id.image_display); } @Override protected void onResume() { Log.e(TAG, "onResume"); super.onResume(); } public void pressedStart(View view) { new SlideShowTask().execute(); } private class SlideShowTask extends AsyncTask&lt;Void, Drawable, Void&gt;{ private Bitmap mFaceBitmap; private AssetManager mAssetMan = null; private String[] mImgFileNames = null; private int mBitmapWidth; private int mBitmapHeight; @Override Protected Void doInBackground(Void... params){ mAssetMan = getAssets(); Log.e(TAG, "pressedStart"); try { mImgFileNames = mAssetMan.list("my_subfolder"); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } Log.d(TAG, "mImgFileNames = " + mImgFileNames); Log.d(TAG, "number of image files = " + mImgFileNames.length); for (int i = 0; i &lt; mImgFileNames.length; i++) { Log.d(TAG, "image file name = " + mImgFileNames[i]); InputStream istr = null; try { istr = mAssetMan.open("my_subfolder/" + mImgFileNames[i]); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } // load the photo Bitmap b = BitmapFactory.decodeStream(istr); mFaceBitmap = b.copy(Bitmap.Config.RGB_565, true); b.recycle(); mBitmapWidth = mFaceBitmap.getWidth(); mBitmapHeight = mFaceBitmap.getHeight(); Log.d(TAG, "mBitmapWidth = " + mBitmapWidth); Log.d(TAG, "mBitmapHeight = " + mBitmapHeight); Drawable drawable = new BitmapDrawable(getResources(), mFaceBitmap); publishProgress(drawable); SystemClock.sleep(5000); } } @Override Protected Void onProgressUpdate(Drawable... values){ super.onProgressUpdate(values); mIV.setImageDrawable(values[0]); mIV.invalidate(); } } } </code></pre>

    1. COAn AsyncTask cannot be used in a loop. Does that mean I have to put the loop in the AsyncTask?

    2. CO@hubeir No what you do is pass in the image you want loaded within your application to do in background. Get the image then use publish progress to update the image on your background. Then do sleep for 5 seconds after. It will look something in psudocode: `doInBackgroupd(String params....){ for (int i = 0; i <=5; i++){ bitmap b = getimage(imagename); publishprogress(b); sleep(5000);}}`This way the loop will happen in the AsyncTask until it shows 5 pictures with 5 seconds between each one. Ill update my answer with example in a second.

    3. CO@hubeir I just finished rewriting your code on my laptop. I will be home in about an hour so I will post it in an edit. I tested it and it is working fine all pictures show for 5 seconds.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
