    <p>I try to load a remote image from a server and thanks to a lot of code examples on stackoverflow I have a solution which works in 2 out of 3 images. I don't really know what the problem is with the third picture and sometimes when letting the code run in the debugger the picture is loading. Also if I load the problem picture first the other two pictures are sometimes not loaded.</p> <p>Here is the code:</p> <pre><code>public static Drawable getPictureFromURL(Context ctx, String url, final int REQUIRED_SIZE) throws NullPointerException { //Decode image size BitmapFactory.Options o = new BitmapFactory.Options(); int scale = 1; if (o.outWidth &gt; REQUIRED_SIZE) { scale = (int) Math.pow(2, (int) Math.round(Math.log(REQUIRED_SIZE / (double) Math.max(o.outHeight, o.outWidth)) / Math.log(0.5))); } Log.i(Prototype.TAG, "scale: "+scale); //Decode with inSampleSize BitmapFactory.Options o2 = new BitmapFactory.Options(); o2.inSampleSize = scale; Bitmap bmp; try { bmp = BitmapFactory.decodeStream((InputStream) Tools.fetch(url), null, o2); if(bmp!=null) return new BitmapDrawable(ctx.getResources(), bmp); else return null; } catch (Exception e) { Log.e(Prototype.TAG, "Exception while decoding stream", e); return null; } } </code></pre> <p>During debugging I found out that o.outWidth is -1 which indicates an error, but no Exception is thrown, so I can't really tell what went wrong. The InputStream always returned a valid value, and I know that the picture exists on the server.</p> <p>Best wishes, Daniel</p>

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.
