Objective This is the main implementation of an Android application, static broadcast, dynamic broadcast two ways to change the content of the widget, that is, in the blog on the basis of the experiment to modify, so the focus of this experiment is the realization of appwidget small parts ~ First, let's simply say what the widget is. The application window widget (widget) is a tiny application view that can be embedded in other applications (such a

on a 4-byte boundary (4 bytes is a good value) so that the Android system can use the mmap () (Please check the purpose of this function yourself) The function reads the file and can get high performance on the read resource, Ps:1. Alignment on a 4-byte boundary means that, in general, the compiler bar 4 bytes as a unit for reading results, so that the CPU can be efficient and fast access to variables (compared to the previous misaligned). 2. T

Android based on the linux2.6+ kernel, we look at a picture to have a perceptual understanding of the architecture of Android system.We briefly explain from the kernel layer:1, kernel layer: Based on the linux2.6+ core, at the same time do some embedded environment to do some targeted optimization adjustment.2, libraries layer: including the Bionic C library, as well as the HAL (Hardware-driven interface ab

If you design and develop a web app on an Android device, you should consider the display of Web pages on different screens.

About the Android architecture, because of the limitations of the mobile phone, I do not think there is really much to talk about, but from the perspective of development, see neat code, graceful layering is always a comfortable enjoyment.From the artistic point of view, we are actually pursuing a kind of beauty.This article analyzes several of today's more popular Android software packages , and finally we

Through the introduction of the official article of the previous translation we have a preliminary impression of Sencha, and we have also generated the first sample application code framework through the wizard, so the next step may be that many people feel that you should look at the details of how an app is built, based on what the wizard suggests. But I think we can change the path of learning.Heaven Zhuhai The rudder is a relatively quick buck, so

How you run your app depends on two things: whether you have a real Android-powered device and whether you're using Eclipse. this lesson shows you how to install and run your app on a real device and on the Android emulator, and in both cases with either Eclipse or the command line tools.

This article is an example of the app widget usage for Android development. Share to everyone for your reference, specific as follows: Controls placed on the desktop are called--app widgets, such as buttons, pictures, and so on on the desktop, such as Control Panel of the desktop player The Appwidgetproviderinfo object, which provides metadata for the

For details, refer to the Android ApiDemo sample resolution (39 ): app-> Service-> Local Service Binding.If you use Remote Process to call AIDL, Android uses the Thread pool managed by the current Process to distribute function calls. Therefore, your Servic

Intent object for receiving app widget Broadcast Appwidgetprovider is just a convenient class. If you want to directly receive app widget broadcasts, You can implement your own broadcastreceiver class or override the onreceive (context, intent) callback method. You need to care about the following types of intent objects: Action_appwidget_update Action_appwidget_deleted Action_appwidget_enabled Action_appwi
