The combination of Html pages and Java code is generally used when the interface is often changed. You can talk about html in the network. Once the software is opened, it will access the network to obtain the latest interface. The disadvantage is that the access speed is slow due to the impact of network signals.

Call the phone to learn how to use intent.
Because it is a small program, you can use the UI interface> Activity> business layer to write code from top to bottom.

The Android system also provides a component called a "Service" that typically runs in the background.

Therefore, in the implementation of the data source component, the Write optimization strategy should be referred to the upper call to implement, or the underlying data store to deal with.Once the data source component is constructed, it remains in a long-running state until the process in which it resides is reclaimed
Although the app is not so tall, but the confusion of the code represents the programmer's sense of responsibility for the app, but also a little guarantee of the security of the app. Today I will do the process of Android confusion and share to everyone, but also to avoid people less detours, less jump pits.This blog
