    <p>I can succesfully connect, send and receive data by using httpurlconnection. But it takes very long time to load all the data on my phone (Samsung s4, 4.2) and on android 4.2 emulator. But it takes almost 1-2 seconds (which is very fast) to load pics on Android 2.3.x emulator. Faster than my galaxy s4 on http connection.</p> <p>I'm using AsyncTask and my code works fine on both. It is just slow on android 4.2s. I tried removing chunkedStreaming, keep alive, changing timeout values etc. but still no success</p> <p>Here is my code</p> <pre><code>HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); urlConnection.setRequestMethod("POST"); urlConnection.setDoOutput(true); urlConnection.setDoInput(true); urlConnection.setUseCaches(false); urlConnection.setChunkedStreamingMode(0); urlConnection.setRequestProperty("Connection", "Keep-Alive"); urlConnection.setConnectTimeout(6000); urlConnection.setReadTimeout(6000); urlConnection.setRequestProperty("Content-Type", "multipart/form-data;charset=UTF-8;boundary="+boundary); urlConnection.connect(); </code></pre> <p>Are there any differences between 4.2's and 2.3.x's httpurlconnections? Whats wrong here</p> <p>UPDATE!</p> <p>I tested by using Log.e() to see which line takes most time.</p> <pre><code>///// other staff ////...... Log.e("HTTP","3"); if (isCancelled()) return (null); // don't forget to terminate this method Log.e("HTTP","3"); //Output DataOutputStream outputStream = new DataOutputStream( urlConnection.getOutputStream() ); //Send Passcode Log.e("HTTP","4"); </code></pre> <p>Between 3 and 4, 5-6 second passes on the line </p> <pre><code>DataOutputStream outputStream = new DataOutputStream( urlConnection.getOutputStream() ); </code></pre> <p>UPDATE!!</p> <p>That waiting time (see previous update) is related to the urlConnection.setConnectTimeout(6000);</p> <p>When I make Timeout 1000, then connection responses quickly (waiting 1 second for the line)</p> <pre><code>DataOutputStream outputStream = new DataOutputStream( urlConnection.getOutputStream() ); </code></pre> <p>No idea why this is happening</p>

    1. COyou don't need to setDoInput, also, setting DoOutput to true automatically sets the method to POST so you don't need to setRequestMethod. I never needed to set any timeouts, requestProperty or chunkedStreamingMode, have you tried removing those? I also don't use `.connect()`, I `getOutputStream()` and `getInputStream()` right after setting the request parameters.

    3. COdo you .disconnect() at the end? a common way is to wrap the urlConnection code with try/catch/finally block and call urlConnection.disconnect() in finally

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.
