Android development: Message Mechanism Overview A few days ago, I discussed the message mechanism in Android with my colleagues and explored the message sending and receiving processes and the relationship with threads. Although we often use these basic things, our understan

Background requirementsIn Android, when you encounter a child thread that needs to refresh the UI, the most common practice is handler, and of course there are other handy ways such as Android gives us the Runonuithread (runnable) method, But it all boils down to using handler to refresh the UI.How Android Message deli

With the framework, we don't have to deal with naked OS APIs and do repetitive and complicated things. However, there is no free lunch in the world. We still need to learn how to use different frameworks efficiently and correctly. Many methods to deal with a specific problem are different in different frameworks. In Android, the lower layer is the kernel of Linux, but the framework made by the upper layer of Java makes all the encapsulation airtight.

The text message files read in Android include [Java]/*** All text messages*/Public static final String SMS_URI_ALL = "content: // sms /";/*** Inbox text message*/Public static final String SMS_URI_INBOX = "content: // sms/inbox ";/*** Send a text message to the sender*/Publ

The solution should be to create a message object, then send it with handler, and then get the message object just sent in the handler Handlemessage () method, and then the UI action here will no longer crash.Thi

The Android system sends many system-level broadcasts, such as a screen shutdown and low battery broadcast. The same app can initiate custom "developer-defined" broadcasts. Broadcasting is one of the ways that messages are sent from one app to another.Broadcastreceiver is a component that listens and responds to broadcasts. In this article, we'll show you how to send a custom broadcast and how to use the ma
