Scheme Jump ProtocolOverview: The scheme in Android is an intra-page jump protocol, a very good implementation mechanism, by defining their own scheme protocol, it is very convenient to jump to the various pages in the app,Through the scheme protocol, the server can be customized to tell the app which page to jump to, you can customize the jump page through the notification bar message, you can jump through the H5 page and so on.Application Scenarios

Android launches four different ways to standard,singletop,singletask,singleinstence. Standard is the most common activity startup method and the default way to start. When you start an activity, he will go to the top of the stack that returns the stack. The system does not manage to have the same activity in the stack, in the same way as after the first out. singletop mode is when the activity starts, the system first determines whether the top of

Refer to "Professional Android 4 Development" Fragment Introduction Fragment is that we can separate the activity into components that have their own lifecycle and UI. Its greatest use is to fit different screens. Create fragment There are many similarities between fragment and activity, for example, without the UI, but it doesn't seem to make much sense for both. They are also created in similar ways, such
