    <p>I have a web service to retrieve images which are converted to string and in my android app convert back to binary array. but unfortunately in stops with a force close error.<br> I'm using the code explained here to fill the imageView:<br> <a href="https://stackoverflow.com/questions/3520019/display-image-from-bytearray">display image from byteArray</a> </p> <p>This is my web service method in C# which sends me the data: </p> <pre><code>public String GetPersonImage() { int PersonCode = 1; JPerson person = new JPerson(PersonCode); Image personImage = person.PersonImage; if (personImage == null) return "Nothing"; using (MemoryStream ms = new MemoryStream()) { personImage.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg); return Convert.ToBase64String(ms.ToArray()); } } </code></pre> <p>And this is how I'm trying to put my data in an ImageView:</p> <pre><code> String pic = t.execute().get(); byte[] picData = pic.getBytes(); ImageView imgPerson = (ImageView) findViewById(R.id.imgPerson); Bitmap bitmap = BitmapFactory.decodeByteArray(picData, 0, picData.length); imgPerson.setImageBitmap(bitmap); </code></pre> <p>the pic variable contains the data from web service. And this is my log cat:</p> <pre><code>11-13 14:08:23.092: D/dalvikvm(29229): GC_FOR_ALLOC freed 2290K, 41% free 8004K/13420K, paused 27ms, total 27ms 11-13 14:08:23.092: I/dalvikvm-heap(29229):

    2. COirrelevant to the question, but you are using an asynctask and calling get on it on the uitread. you are blocking the main thread exactly as if you were making your request on the ui thread. please don't do that and handle your server response in the onPostExecute method.

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).
