    <p>I'm trying to get and display a WEBP icon from Google PlayStore, like this one : <a href="http://lh5.ggpht.com/YK0as9_ZRmSK6PBkSwRVQ62F5cBMq7gYMLfZ2nk30QjEVK6taYMPMKzh0eswMkBMhw=w170-rw" rel="nofollow">http://lh5.ggpht.com/YK0as9_ZRmSK6PBkSwRVQ62F5cBMq7gYMLfZ2nk30QjEVK6taYMPMKzh0eswMkBMhw=w170-rw</a></p> <p>I tried using directly the data and decoding it with BitmapFactory (works sometimes ...), I also tried with the libwebp but when I test the data with the "WebPGetInfo" function it returns 0 (wich means the datas are not webp image ...)</p> <p>Here is the code I use with libwebp:</p> <pre><code>public static Bitmap getBitmapFromURL(String src) { HttpURLConnection connection = null; Bitmap bmp = null; try { connection = (HttpURLConnection) new URL(src).openConnection(); connection.setRequestMethod("GET"); connection.setUseCaches(false); connection.setDoInput(true); connection.setDoOutput(true); connection.setRequestProperty("Content-Type", "image/webp"); connection.connect(); //Send request DataOutputStream wr = new DataOutputStream ( connection.getOutputStream ()); wr.writeBytes (""); wr.flush (); wr.close (); //Get Response BufferedReader rd = new BufferedReader(new InputStreamReader(connection.getInputStream())); ByteArrayOutputStream baos = new ByteArrayOutputStream(); byte[] buf = new byte[4096]; while(true) { String n = rd.readLine(); if(n == null)break; baos.write(n.getBytes(), 0, n.getBytes().length); baos.write('\n'); } byte data[] = baos.toByteArray(); // From the lib's exemple int[] width = new int[] { 0 }; int[] height = new int[] { 0 }; int test = libwebp.WebPGetInfo(data, data.length, width, height); // test = 0 ! ! ! byte[] decoded = libwebp.WebPDecodeARGB(data, data.length, width, height); int[] pixels = new int[decoded.length / 4]; ByteBuffer.wrap(decoded).asIntBuffer().get(pixels); bmp = Bitmap.createBitmap(pixels, width[0], height[0], Bitmap.Config.ARGB_8888); } catch (IOException e) { e.printStackTrace(); } return bmp; } </code></pre> <p>Thx for your help.</p> <p>EDIT : After multiple changes I now have a NoClassDefFoundError when using libwebp ...</p>

    1. COI will not post this as an answer because I assume you will want to solve the problem in app. I have had other image issues where the solution was to have a simple proxy web service convert, cache and send images in our desired format.

    2. COI'll try that, but since the debug is telling me that the datas I got from the URL are bad maybe it will be the same.

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).
