But if the developer wants to use the API in a version below 3.0, then nine old androids is your best choice, and the API is exactly the same as the Honeycomb API. Just changed the entrance y

Android has two sets of HTTP APIs, just beginning to use network programming is somewhat confusing in the end with which good? In fact, there's no need to argue, but Google has pointed out that httpurlconnection is a better choice for Android and that it references blogs in the SDK documentation (requiring proxy access) http:// Android-developers.blogspot.com/2011/09/androids-http-clients.html to illustrate their strengths and weaknesses. Some of the

Later analysis, originally the difference should not have so big, estimate is gzip compression credit, but the connection speed on HttpURLConnection is also a little faster.Google itself is also recommended to use HttpURLConnection, it has been a lot of optimization, this from the Android Help document can be seen:Http://developer.android

Recently in the study of the source code of the volley framework, found that it is more interesting in the use of HTTP requests, in Android 2.3 and later, using the HttpURLConnection, and in Android 2.2 and below, using the httpclient. I am also more curious about the reasons for this use, so specifically found a Google engineer wrote a blog, the text of HttpURLConnection and httpclient in contrast, I will give you a brief translation.Original address: http://android-developers.blogspot.com/2011

I encountered a scenario where I needed to customize the splitter line of the ListView, which was made up of two lines, and it was difficult to use XML drawable.Note: Draw two lines is to achieve the effect of the sunken, in the drawing of a dark line followed by a clearly will give a person visually obvious "ditch" feeling.Because my background is transparent (background gradient), directly with the picture to achieve the effect is not good.Look at the effect:Use Layer-list to implement.Layer-l

Hot on the heels of our previous GUI article, iPhone and iPad development GUI kits, today we focus on Android development. the idea is the same: to help streamline your app design and development, with a fairly comprehensive collection of Android GUI kits, icons, fonts ,. PSDs and tools, that will allow you to focus on developing rather than having to design everything from scratch. In comparison to apples iPhone, the android interaction design guidelines are far from being extensive nor are the

On the official blog, android engineers talked about how to choose apache client and httpurlconnection:See http://android-developers.blogspot.com/2011/09/androids-http-clients.html for more informationHere we will summarize the following points.1) apache httpclient is relatively stable and has few bugs. However, due to the API relationship, it is difficult to scale up and transform,Therefore, the android team is no longer familiar with this.2) httpurl

There are some special buttons in the system that need to be processed by the system, such as volume and power keys. It is intercepted by interceptKeyBeforeDispatching () and interceptKeyBeforeQueueing () functions. InterceptKeyBeforeDispatching () is mainly used to process home, menu,
