Recently, I have seen some questions from colleagues in various Android technology development groups about how to
building a project in Android studio. Steps to upload the project to GitHubWait patiently for your project to appear on the GitHub website.

MessageQueue, and then looper out, sent to handler call display, sub-threading because there is no looper, So we need to add looper.prepare and Looper.loop to create a looper, but in essence, this is still called on the child thread, so it will be an error!So why does Android require the view to be changed only in the main thread of the UI? This is about Android's single-threaded model, because the resulting thread synchronization and thread-safety i
There are two sets of methods for implementing view updates in Android, one for invalidate and the other for Postinvalidate, which is used in the UI thread itself and the latter in non-UI threads.
Android provides a invalidate method for interface refreshes, but invalidate cannot be invoked directly on the thread because he violates the Single-threaded model: Android

you want to implement this step in Android, you need to configure the NDK development environment, if you do not want the students can directly put in the demo file.

Android threads are single-threaded. Therefore, Handler is used to update the UI:
Private Handler splashHandler = new Handler (){Public void handleMessage (Message msg ){Switch (msg. what ){Case OVER:ProgressDialog. dismiss ();Break;Default:Break;}Super. handleMessage (msg );}}. After a thread is running, a notification can be sent to Hanler to notify the main th
