    <p>i'm having issues with uploading images in android.</p> <p>i'm using apache httpmime 4.1 lib the code is like this:</p> <pre><code>MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE); reqEntity.addPart("image", new FileBody(new File(AndorraApplication.getPhotosPath() + "/" + entity.getFileName()), "image/jpeg")); resp = NetworkUtils.sendHttpRequestMultipart(EXPORT_PHOTOS_URI, reqEntity); </code></pre> <p>NetworkUtils class:</p> <pre><code>public class NetworkUtils { public static final int REGISTRATION_TIMEOUT = 3 * 1000; public static final int WAIT_TIMEOUT = 5 * 1000; public static HttpResponse sendHttpRequestMultipart(String uri, MultipartEntity entity) { HttpClient mHttpClient = new DefaultHttpClient(); final HttpParams params = mHttpClient.getParams(); HttpConnectionParams.setConnectionTimeout(params, REGISTRATION_TIMEOUT); HttpConnectionParams.setSoTimeout(params, WAIT_TIMEOUT); ConnManagerParams.setTimeout(params, WAIT_TIMEOUT); HttpPost post = new HttpPost(uri); post.addHeader(entity.getContentType()); post.setEntity(entity); HttpResponse resp = mHttpClient.execute(post); } } </code></pre> <p>sometimes everything works fine, but sometimes (especially on a slow connection) the image is uploaded very corrupted. the example is here: <a href="http://pixelbirthcloud.com/574_orig.jpg" rel="noreferrer">http://pixelbirthcloud.com/574_orig.jpg</a></p> <p>it doesn't throw any exceptions. the lenght of the uploaded file is same as the original one.. tried to change mime type to application/octet-stream or remove it at all. tries playing with timeouts. still same result. end users upload corrupted images almost all the time (although i managed to get bronem images just 2 times only).. the image size was 2.5 megs at first, but then i reduced it to 500-700 kb. didn't fix the problem though. </p> <p>haven't tried to change the apache's library.. maybe it is the problem.. but as far as i read the net, nobody was experiencing this with httpmime library.</p> <p>what can it be? i'm completely lost now :(</p> <p>the other issue is that timeouts sometimes not working.</p> <p>like when it comes to this line: HttpResponse resp = mHttpClient.execute(post); and i disable 3g connection it just waits for like 17-20 minutes instead of 3 or 5 seconds.. and only then throws exception. tried different methods. like this:</p> <pre><code> HttpParams params = new BasicHttpParams(); HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1); HttpProtocolParams.setContentCharset(params, HTTP.UTF_8); HttpProtocolParams.setUseExpectContinue(params, false); HttpConnectionParams.setConnectionTimeout(params, 10000); HttpConnectionParams.setSoTimeout(params, 10000); ConnManagerParams.setMaxTotalConnections(params, 5); ConnManagerParams.setTimeout(params, 30000); SchemeRegistry registry = new SchemeRegistry(); registry.register(new Scheme("http",PlainSocketFactory.getSocketFactory(), 80)); registry.register(new Scheme("https",PlainSocketFactory.getSocketFactory(), 80)); ThreadSafeClientConnManager manager = new ThreadSafeClientConnManager(params, registry); HttpClient httpclient = new DefaultHttpClient(manager, params); </code></pre> <p>but still doesn't work :)</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.
