Which is best used for downloading data - AsyncTask or AsyncTaskLoader

There's a dish that emits some lines from the Internet page, and then it's gonna take them out. ListView♪ Tell me what's best to use, normal. AsyncTask or AsyncTaskLoader? Because I started doing it. AsyncTask and it's kind of working, but it's found out there's a specially created class for this job.

Use class AsyncTaskLoader preferable, allows for better handling of the load through LoaderManagerthe change in condition (returns of the device) is not painful, and it is also possible to monitor the change in https://stackoverflow.com/questions/7120813/asynctaskloader-vs-asynctask ♪

The namespaces are similar in several programming languages, such as this answer explains https://pt.stackoverflow.com/a/16690/3635 (even the subject being a different language)I make the words of Maniero mine:He doesn't encapsulate anythingThis understanding shows that despite the view programmers have about the namespace being a module, a type box (as the first function indicates), in reality it functions as a last name for the types. A surname works as a way to name a family. So you can have two Ricardos in the same environment without confusion, because one is Oliveira and the other is Silva.Having understood what utility, we will understand how it works in PHP. In languages like Java, Actionscript and C# the namespaces are associated with "natively" files, already in PHP this does not occur, you have to use require or include manually, i.e. I have to create something like this:foo.php<?php namespace Foo\Bar; class Baz { public function hello() { echo 'Olá mundo!'; } } index.php<?php use Foo\Bar\Baz; require 'foo.php'; $test = new Baz; Use of "use"O use does nothing, even with spl, in PHP it only serves to create nicknames, for example suppose you have two classes that the name is the same if you do this:<?php use Aa\Bb\MinhaClasse; use Xx\Yy\MinhaClasse; When to use MinhaClasse he would conflict, so you can use this:<?php use Aa\Bb\MinhaClasse; use Xx\Yy\MinhaClasse as MinhaClass2; $a = new MinhaClasse; $b = new MinhaClasse2; That's the moment you use this:<?php use Foo\Bar\Baz; $test = new Baz; You're just creating a "fast appeal."There is also the possibility to use directly:<?php $a = new \Aa\Bb\MinhaClasse; $b = new \Xx\Yy\MinhaClasse; Note that within namespaces you can add others, such as functions and believe that even perform some things, example of functions:<?php namespace Foo\Bar; function file($path) { ... } In this way will not conflict with the native function of called php file:file('oi.txt'); \Foo\Bar\file('oi.txt'); Enjoy and read about the native functions and namespaces here: https://pt.stackoverflow.com/q/78007/3635 The SPLThe SPL is a set of native PHP functions and classes that have been created to solve a number of situations, such as PHP does not natively load, but it is possible to use the spl_autload, as I explained here https://pt.stackoverflow.com/a/88039/3635 , in this way the files will be associated by splitting folders to namespaces, similarly to C#, Java and Actionscript3 languages.ExtrasHow @WallaceMaxters explained in https://pt.stackoverflow.com/a/104479/3635 , this has been implemented since PHP5.3, i.e. well before PHP7@rray also gave a hint of how to "write less" (only for PHP7), so you can group the classes of a namespace https://pt.stackoverflow.com/a/104426/3635 , example:use Foo\Bar\DB{Relaciona, NoSQL, LDAP};

I think we should point out the directory for the file. For example: String dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS).getPath() + "/highscore.txt" f = new File(dir); And don't forget the femur in the manifest: <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> http://startandroid.ru/ru/uroki/vse-uroki-spiskom/138-urok-75-hranenie-dannyh-rabota-s-fajlami ♪

If the application has done your ideal thing is to use the technologies XML+XSLT. Or you could use JSON+Javascript in a similar way to generate HTML via DOM, but it's much more expensive than XSLT.XML+XSLT is not well known unfortunately but highly optimizes the data sent by the server to the browser.Since the only dynamic (what changes) is the XML you generate in PHP, which contains the data (e.g. article name, price, description, ....).Everything else that is always repeated on a web (html heads, menus, foot, ...) can be passed to an XSLT template, these are always the same and do not change, so the browser does not re-download them every time having them cacheadas. You also move the XML merge with the template to the browser, so you remove the server from work.XSLT are templates that apply to the XML, more or less like the CSS regarding HTML, but the XSLT templates have quite advanced things like loops (for), matchs (for each xml element do something), sentences if, switch(case), ....This technology can be applied to the entire website, or apply only to the load of search results, page of articles, etc.There are several options:You have a normal PHP web that generates HTML, with your CSS, Javascript. You modify the part of the searches of the web (the search results pages) the passes to AJAX, said AJAX will get the XML with the data and then via Javascript you will apply the corresponding XSLT template for the JavaScript object XSLTProcessor.Another more complex option is that your pages are actually XML generated by PHP, to which the browser directly applies the XSLT (a header is used in the XML style the <style> from HTML. Obviously it forces you to schedule the entire web with XSLT templates that depending on the complexity of it can be quite complex to perform.I'll leave you a few links so you can see its operation a bit:Applying XSLT templates using Javascript https://www.w3schools.com/xml/xsl_client.asp http://www.mclibre.org/consultar/xml/lecciones/xml_xslt.html https://www.w3schools.com/xml/xsl_intro.asp

In order for you to pass an object as a parameter it is necessary that it be Serialized, that is, implement Serializable. Here’s a simple example: Class: public class Params implements Serializable{ public String param1=""; public String param2=""; public String param3=""; } Setting the parameter: Params obj = new Params(); obj.param1 = "Parametro UM "; obj.param2 = "Parametro DOIS "; obj.param3 = "Parametro TRES "; Intent it; it = new Intent(context, MainActivity.class); it.putExtra("Param", obj); Greetings

The root of evil is here:loadLocalData = new LoadLocalData(getActivity()); dbHelper = new DBHelper(getActivity()); Realm.init(getActivity()); It cannot be assumed that the activities available in the creation of the wine will always exist. Especially in combination with:setRetainInstance(true); The fragment has its life cycle.onAttach()/onDetach()I'd like to point out that the activists are already there or they're no longer for fragmentation.

How do we track down the Android application?When the application is down, the method is to be used onStop() activate. Reclassify this method and operate it to close the application.But actually, in Android No need to manually close the annexes.♪ The management of the applications is a function of the DS itself, which, if necessary, will unload your app from memory.When your application is down, a method will be called onStop() activate and then the method onDestroy()after which your activism will be completed. But this will not lead to the immediate completion of the annex.Good. https://stackoverflow.com/a/2034238/7129209 On this subject.

Non-professional opinion here (not a security guy, more of a software dev), but I'd say in the right hands: more secure, considering how many phone manufacturers are not issuing critical updates to the Android operating system, and how many phones are just running around with giant exploits in them. Also the source code is available, you, as far as I know, can compile it yourself (download from Google, grab drivers for your phone from one of the various projects providing these drivers, review/compile them together) if you're really paranoid. Furthermore, people putting hacks into your open-source software is a lot more difficult, being as you have a ton more eyes on the code, and anyone can speak up and reference code that they've forked (hence the original guys can't take it down), and it would pretty much be the end of those guy's professional career. Edit: HBoot isn't open source, however they do have alternative open-source bootloaders along with projects analyzing hboot: http://tjworld.net/wiki/Projects/Bootloader-AP

I guess you're using jQuery. $.ajax) and CodeIngniter (on the part of $this->db->select). If both are true, then you must change your code by:$("#rut_estu").keyup(function(){ Well, you missed the symbol. $As for PHP, CodeIgniter returns the full object to you when running $this->db->get()->result()So you should change the code by:echo $estudiante[0]->estudiante; Well what you want is the value of the column estudiante (according to your consultation)

Internal Server Error If the cause is not timeout, the problem will not be solved even if it is not timeout. For example, there is a possibility that there is too much data and there is not enough memory. Please log Flask execution log and check the log if an error occurs.If the cause is timeout, it is necessary to shorten the response time to the browser. There is a way to implement asynchronous processing for that. The library called Celery is often used in Python for asynchronous processing. More http://www.celeryproject.org/ Sorry, this entry is only available in Japanese.
