10,541,712 | 0 | Web app on android browser WIDTH issue <p>So I've only experienced this issue on the Android browser so far. Basically my site works fine almost all the time (and I've not seen the problem yet on Dolphin, Opera or Skyfire) but occasionally when I reopen the Android browser from a bookmark on one of my phone's homescreens my site appears stretched horizontally, so now I only see the first 2/3 of the left hand side. Its' as though the browser just lost the CSS or the meta information while it was minimized. Here are my meta tags, and I'm using width 100% in my table styles.</p> <pre><code><meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <meta name="keywords" content="Task, Tasks, Goal, Goals, Habit, Habits, Track, Tracking, Best Habit Tracker"/> <meta name="description" content="Top Habit Tracker!"/> <meta name="mobileoptimized" content="0"/> <meta name="viewport" content="width=device-width, initial-scale=1.0"/> </code></pre> <p>This issue only seems to happen when the bookmark is clicked after about 30 min. to reopen the stock Android browser. Then, it seems browser gets the page from its cache, but still runs window onload for ajax, so I'm thinking the combination of it using a browser-cached page with (maybe?) the javascript DOM manipulations from ajax on top is something that the Android stock browser uniquely has problems with, breaking my table width outside the viewport. Or maybe the DOM changes have nothing to do with it.</p> <p>If the phone is switched off, then on, and the bookmarked clicked, the stock browser reloads the page from the server, then I don't get the problem. If the browser is minimized, and the bookmark re-clicked after just 2 minutes, no problem either because the browser just re-displays itself and the last page exactly as it was left, without doing anything.</p> <p>I've been thinking of some kind of hack I could throw on top to force a reload from server in the case where the page is grabbed from brower cache, or I guesss I could try turning off browser caching, but I'm wondering about the implications of doing that on images, css, load time etc. Weighing up my options... thoughts welcome.</p> <p>UPDATE: Well turning off browser caching may have reduced the incidence of this issue (not sure?) but definitely didn't cure it. I'm now thinking I may be having the same issue as described in this blog post:</p> <p><a href="http://www.gabrielweinberg.com/blog/2011/03/working-around-androids-screenwidth-bug.html" rel="nofollow">http://www.gabrielweinberg.com/blog/2011/03/working-around-androids-screenwidth-bug.html</a></p> <p>UPDATE: OK nothing I've tried so far has prevented this intermittent issue in my Android stock browser. I'm going to switch my regular use of my app to Dolphin for a while to see if the issue occurs in that browser. What I've tried so far is: using meta tags to disable browser caching (I think to some extent the Android browser ignores that anyway)... changing the table width (I may try that again in a different way)... Using the solution posted at comment 14 here (dynamically creating CSS link): <a href="https://code.google.com/p/android/issues/detail?id=11961#c14" rel="nofollow">https://code.google.com/p/android/issues/detail?id=11961#c14</a> and lastly I've tried appending Datetime ticks to the URL in an effort to alleviate caching, that hasn't worked either.</p> <p>More useful info here: <a href="http://f055.tumblr.com/post/6364300769/viewport-bugs-in-android-browser" rel="nofollow">http://f055.tumblr.com/post/6364300769/viewport-bugs-in-android-browser</a></p> |

Android Studio with Gradle and Maven are soooo powerful, that you are losing so much time using Eclipse. </p> <p>Of course, you will have to pass all these painful steps, like we all did. What is Gradle? What is Maven? How do I import library? Where is my code? Why my Manifest does not work? And so on...</p> <p>so I strongly advise you find a week of your time and learn new IDE by fixing all those things that will arise when you do conversion. </p> <p>But in the end, you can still use Eclipse or IntelliJ IDEA the old way and leave learning to some other time. </p> |

Aside from saving <code>Parcelable</code>s to Activity's <code>Bundle</code> in <code>onSaveInstanceState</code> docs are suggesting using <code>Fragment</code> with <code>setRetainInstance</code> flag set to true.</p> <p>But I've just come across some code that uses <code>onRetainCustomNonConfigurationInstance</code> to hold arbitrary objects (in a fancy way, but essentially big objects without references to <code>Activity</code> etc.). I have never seen this method used, so I have some doubts:</p> <ul> <li>Is this method safe to call to store arbitrary objects (in a sense that I can be pretty sure it's gonna get called, and that it won't be deprecated/removed anytime soon)?</li> <li>How is this method different from <code>onRetainNonConfigurationInstance()</code>, which also should return <code>Object</code>, and in essence should work similarly?</li> <li>Is using retained fragment still better, for some reason?</li> </ul> <p>As a bonus, I would be grateful for any other tips or solutions to save state of objects like <code>AsyncTask</code>, <code>Observable</code>, view's presenters and go on</p> |
33,354,772 | 0 | PHP Open SSL Decrypt Failing Inconsistently <p>I'm having some weird behaviour with the <code>openssl_decrypt</code> method in PHP. It's failing, giving me an error: <code>Unknown cipher algorithm</code>, but only <em>sometimes</em> (about 6:10 times) i.e. If I run the command enough times, it will eventually work... My code is: </p> <p><code>$result = openssl_decrypt(base64_decode($hash), 'AES-128-CBC', $timestamp);</code></p> <p>running <code>openssl list-cipher-commands</code> lists AES-128-CBC as one of the available cipher methods. The specs don't really list anything on the subject - only specifying that <code>unknown cipher algorithm</code> is a possible exception from running the command.</p> <p>edit: Using the command line: i.e. running <code>echo "soemthing" | openssl enc -aes-128-cbc</code> on a random machine and then decrypting on the machine that fails with the above <code>echo "..." | openssl enc -aes-128-cbc -d</code> works consistently.</p> |

Use <a href="http://download.oracle.com/javase/tutorial/jdbc/basics/prepared.html">prepared statements</a> so you won't have problems with <a href="http://en.wikipedia.org/wiki/Sql_injection">SQL injection</a>.</p> <p>Instead of</p> <pre><code>statement = connection.createStatement(); </code></pre> <p>use</p> <pre><code>statement = connection.prepareStatement(String sql); </code></pre> <p>With this, your query becomes</p> <pre><code>"select distinct group_name From group_members where username= ?" </code></pre> <p>and you set username with</p> <pre><code> statement.setString(1, username); </code></pre> <p>Next, I don't like use of your <code>myDB</code> class. What if results is <code>null</code>? You're not doing any error checking for that in your <code>public List<InterestGroup> getGroups()</code> method. </p> <p><code>public void sendQuery(String query)</code> seems to me like it shouldn't be <code>void</code>, but it should return a <code>ResultSet</code>. Also, search on the net for proper ways to do JDBC exception handling.</p> <p>Also, this line:</p> <pre><code>new InterestGroup(results.getString("group_name"), myDB) </code></pre> <p>Why do you have <code>myDB</code> as a parameter?</p> <p>I'd suggest adding more <code>System.out.println</code> statements in your code so you can see where things can go wrong.</p> |

3,669,159 | 0 | <p>I think a lot of the problem deals with the fact that search engines give something a high rank if a lot of people are linking to a specific page. Unless you can get all the people linking to your old documentation, to link to your new documentation, then you are going to have a problem with the older documents being rated artificially high. In order to overcome this, you might need to change the way you handle documentation pages. One good way would be to always show the newest information on a particular topic, and then only by clicking on a link on the page, do you get to the older versions. Optimally, this would be the same page, with a different parameter, to state which version you want to get documentation for.</p> |

21,805,767 | 0 | <p>The problems are caused by this:</p> <pre><code> { (char) c = (int) c - 32 + key + 127; System.out.println(c); } </code></pre> <p>The <code>(char) c = ...;</code> is completely invalid syntax. </p> <p>An assignment is supposed to look like this <code>c = ...;</code>. </p> <p>If you want / need to do a type cast before assigning, the type cast belongs on the right hand side of the assignment operator; i.e. <code>c = (char)(...)</code>.</p> <hr> <p>Anyway, what you have written has cause the Java parser (in your IDE) to get thoroughly confused ... and <em>spectacularly</em> misdiagnose the error as an attempt to declare a constructor, it the wrong context.</p> <p>Unfortunately, this happens sometimes ... though it is compiler dependent. The compiler was trying to be helpful, but the compiler / compiler writer "guessed wrong" about what you were trying to write at that point.</p> <p>Then it appears that the compiler's syntax recovery has inserted a <code>{</code> symbol into its symbol stream in an attempt to fix things. The second error complains that there is no <code>}</code> to match the phantom <code>{</code> that it inserted. Again, it has guessed wrong.</p> <p>But the root cause of this was your original syntax error.</p> <hr> <p>For the record, the <code>int</code> cast in your original expression is not necessary. You <em>could</em> (and IMO should) write the assignment as this:</p> <pre><code>c = (char) (c - 32 + key + 127); </code></pre> <p><strong>Explanation:</strong> in Java, the arithmetic operators always promote their operands to <code>int</code> (or <code>long</code>) before performing the operation, and the result is an <code>int</code> (or <code>long</code>). That means that your explicit cast of <code>c</code> to an <code>int</code> is going to happen anyway.</p> |

10,186,225 | 0 | <p>It is possible to use a custom request handler that enables django's i18n trans tag with google app engine. But much better is use jinja2 like is said here, then the solution is official. You should import jinja2 from webapp2_extras and then your i18n will work and the translation tag for jinja2 will look like <code>{% trans %}</code> and <code>{ % endtrans %}</code>.</p> <p>If you must use django here is a link to an old blod post that presents a custom request handler that you can use if you must use django templates: <a href="http://blog.yjl.im/2009/02/using-django-i18n-in-google-app-engine.html" rel="nofollow">http://blog.yjl.im/2009/02/using-django-i18n-in-google-app-engine.html</a></p> <p>But we recommend that you use jinja2.
