error The amount of memory that is divided by each program in Android is limited, and if it exceeds this number, it will be reported out of the error. The amount of memory that Android assigns to programs is related to the phone's hardware, and here are some of the phone's data:g1:16m droid:24 Nexus one:32m xoom:48msSo try to cache some of the big data in the program to a local file. Avoid exceeding the amount of memory used. Snippets1, passing data

Apple is currently ahead in the tablet market, but apple only has iPad 2. Although iPad 2 is divided into multiple models, the hardware is basically the same. The future policy for Windows tablets may be similar to that for Android tablets. Users will see a variety of products with different appearances and sizes. This diversity provides users with a variety of options.

Google had previously advertised that android was an open-source operating system, but the "honeycomb" was developed in a closed state. Even if the operating system is eventually open-source, some of its components, including the android electronic market and Google Map, will still be private to Google. Google also has a trademark right for Andr
Recently, I 've put all my focus on JavaScript-Driven Web application development. JavaScript is responsible for driving the front-end and back-end. This is a very strange method, especially those tech-olds who have been immersed in traditional server-side technologies (such as PHP) for more than a decade feel incredible. The emergence of several cutting-edge technologies opens the door to building truly immersive interactive Web applications, such Web applications and desktop applications are s

Map width = map Height = 256*2 ^

Map accuracy indicates the actual distance represented by each pixel on the screen. For example, if the precision is 10 m, each pixel represents a distance of 10 m. The accuracy of a map varies with the xoom level and latitude. As

Let's take a second. The decision to peel from the PHP framework is a function of the mobile terminal:
function Is_mobile_request () {$_server[' all_http '] = isset ($_server[' all_http '])? $_server[' All_http ']: '; $mobile _browser = ' 0 '; if (Preg_match ('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|iphone|ipad|ipod|android|xo
We often need to determine whether a mobile phone is accessed and then perform automatic jump operations. This is a function separated from a PHP framework to determine whether it is a mobile phone.
Sometimes it is very useful in some scenarios. Keep it for backup.

I tested Android2.3.3 on Nexus One and Nexus S hardware, tested Android 3.0.1 on Xoom, and tested iOS 4.2 on the ipad and iphone.
In short, all tested browsers support Touchstart, Touchend, and Touchmove events.

All right, we're talking about features that the IPad generation has. However, iPad2 upgrade is not very, the biggest surprise is to see the leader, and

8. Different memory management
The memory of the Dalvik virtual machine can be roughly divided into Java Object Heap, Bitmap memory, and native Heap three kinds.
Java object Heap is used to allocate Java objects, which means that the objects we have in code new are located on the Java object heap. When the Dalvik virtual machine is started, the-XMS and-XMX options are available to specify the minimum and maximum values for Java Object heap. To prevent the Dalvik
