    <p>I want to store an image(from url) into a sqlite database.</p> <p>For that I use: </p> <pre><code>db = new DataBase(getApplicationContext()); URL url = new URL("http://sree.cc/wp-content/uploads/schogini_team.png"); URLConnection ucon = url.openConnection(); InputStream is = ucon.getInputStream(); BufferedInputStream bis = new BufferedInputStream(is,128); ByteArrayBuffer barb= new ByteArrayBuffer(128); int current = 0; while ((current = bis.read()) != -1) { barb.append((byte) current); } ContentValues filedata= new ContentValues(); filedata.put(DataBase.IMG_SRC,barb.toByteArray()); db.insert(DataBase.Table_Img, null, filedata); </code></pre> <p>In the <code>Insert()</code>:</p> <pre><code>public void insert(String tableImg, Object object, ContentValues dataToInsert) { // TODO Auto-generated method stub String sql = "INSERT INTO "+tableImg+" ("+ID+","+IMG_SRC+") " + "VALUES ('"+1+"','"+dataToInsert+"')"; db.execSQL(sql); } </code></pre> <p>For the retrieval of image:</p> <pre><code>Cursor cursor = db.selectDataToShow(DataBase.Table_Img, DataBase.IMG_SRC); byte[] imageByteArray=cursor.getBlob(cursor.getColumnIndex(DataBase.IMG_SRC)); cursor.close(); ByteArrayInputStream imageStream = new ByteArrayInputStream(imageByteArray); Bitmap theImage = BitmapFactory.decodeStream(imageStream); System.out.println("&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt; "+theImage); </code></pre> <p>So here I got <code>null</code>.</p> <p>And in my database the value of image stored as: <code>Image=[B@43e5ac48]</code></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.
