As shown in, if you want to run the entire process, another important thing isIntent FiltersIt is used to describe an activity, serveice, and other components, what kind of intent is expected to respond. For a component, you only want other components to use the explicit it intents (that is, specify the component ...) you

After configuration, click Finish to generate the JAR file of the project.
The blog post only targets Java projects. For Android projects, we can also generate static jar files using the above methods.Use of static jar plug-ins
After creating the static jar plug-in above, we generate a jar plug-in named drawcolor. Jar. The following shows how to load the file to the

At the beginning, we state that activity,activity is the core component of the entire application user interaction, understanding the activity's working mode, life cycle and management style, is the foundation of Understanding Android, this section is the speaker
Widget: Your appwidget will be removed from the desktop.6. Account management: Accounts created with Accountmanager will disappear.7. Sync Adapter: Your abstractthreadedsyncadapter and all of its syncing methods will not work.8. The receiver of the"Boot completed" broadcast: The system will emit a action_boot_completed broadcast between the external storage device, and you will not receive this broadcast if you install an external storage application
The following section describes how android and javascript call each other. In this way, the UI is much simpler to design, and the UI can also be designed to be cross-platform. Now there are a lot of front-end web app frameworks, such as sencha and jquery mobile. We believe that with the development of web apps in the future, we can also use html to design an int
Onresume function is executed, the application is displayed ... In fact, this is an inaccurate statement, because from a system level, an Activity after Oncreate/onstart/onresume these life cycle, just completed the application of some of its own configuration, such as window of some properties of the settings/View tree establishment (Just build, and not show, that is, just call the inflate only). Later Viewrootimpl also calls two times performtraver
