Re: [android-developers] Re: looking for HTML5 and javascript based sdk....
a global event based rendering machine plus HTML5 + javascrip + css Bundle will surely be more faster. firefox os maybe an existing example. it consumes less resources. while android is not. http://propakistani.pk/2013/04/29/how-and-why-firefox-os-is-better-than-android-and-ios/ 2014-05-12 13:52 GMT+08:00 李白|字一日 calid...@gmail.com: you even don't know what javascript is . although javascript needs more than one threads to execute, but it is event based. in run time, it has no needs to create new thread. like epoll vs select in network io. the differences are obvious. java can't make it. the switch between ui thread to network thread is not needed in javascript. but it is a must in java. as to clear, i give some my opinions on why i like javascript and possibly be a fast language: 1、can be compiled to native when possible, requires no vm 2、event based 3、async executed 4、no more threading 5、no inheritance need. 6、object based, prototype based, native to have the ability to extends but require no new classes. 7、no classes to objects translation. 2014-05-12 13:30 GMT+08:00 Kristopher Micinski krismicin...@gmail.com: What are you even talking about: Any JavaScript program is also going to have threads, too. You seem to be making this argument: Java has multiple threads, and that makes the programs slow. It sounds like all of this is coming from a completely uneducated viewpoint on systems design, but there are a number of issues. Please understand, however, that all of the issues in Java carry over (and worse) to JavaScript, you still need multiple threads, you still need a garbage collector. Please also quit citing other Java products as evidence that it has anything to do with Android. Forget Java, android doesn't run Java. Android runs Dalvik. Which is completely different than Java. You can translate anything into Dalvik, people usually translate Java, there's no reason you couldn't also translate anything else.

It sounds like your complaint is that you can't develop native apps in your preferred language and that you're using an outdated claim about Java to support your desire to change the current language of choice for Android development. The XML based components can all be done via code. Do you have an example of how they are far from flexible? There are many limitations, but you are welcome to write your own custom Views to get around any limitations. I have many of my own complaints about some of the UI system, but I have no reason to believe the current state of things would be faster or more flexible if it were in another language. That's not the thing limiting flexibility or causing speed issues, that's more about the implementations. I've created and seen many fast and fluid and complex UIs on Android, but you sometimes have to do some real work to get them and they don't always drop right out of
[android-developers] animated gifs
hi guys, do any of you know a quick way to identify whether an image is an animated gif? more or less I have found how to animate them, but can not find how to detect whether the image I've downloaded from the web is an animated gif or not. Any clue is welcome. Thanks in advance, Iván -- You received this message because you are subscribed to the Google Groups Android Developers group.
