The first step is to export the file data method to be backed up very simply copy directly on the line X:memumemuhyperv Vmsmemu directory Memu-20150613-disk1 and Memu-20150613-disk2 are primary files only back up these two files on the line Second, file data for the import backup first, open the directory where you installed the X:memuhyperv. Memuhyperv Double click to open Click on the interface Gear button then Antu click to delete Memu-20150613-d

English Original: Probably is the best (?) to Save/restore Android Fragment ' sKey points: Fragment's arguments.After years of using fragment, I want to say that fragment is really a smart design, but there are too many problems to be solved by using fragment, especially when dealing with data retention.First, although it has an activity-like onsaveinstancestate, don't think you can keep the data just by Onsaveinstancestate.Here are some examples:Scen

The Splash page for Android performance optimization should be designed in this way.Current SplashActivity Design At present, applications on the market will start a SplashActivity at startup. As a welcome interface, why is this design?Personal summary has three advantages:1. Better User Experience For example, you can dynamically change the welcome image in the background or explicitly welcome xxx back. Sina Weibo's interaction is like this.2. The Ap

I gave this pattern to me named Mve (Model,view,eventbus). Model and view we all know, here is focused on Eventbus.The Eventbus is a publish/Subscribe event bus optimized for Android. The main function is to substitute intent,handler,broadcast for passing messages between Fragment,activity,service and threads. The advantage is that the cost is small and the code is more elegant. and decoupling the sender and receiver.OnCreate inside Register EventBus:

Android network programming is divided into two types: HTTP protocol based, and socket based. HTTP protocol based : HttpClient, HttpURLConnection, asynchttpclient framework, etc. Based on the socket : (1) socket, ServerSocket for TCP/IP (2) for UDP/IP Datagramsocket, Datagrampackage (3) Apache mina framework One, httpurlconnection implementation String response = null; URL url = new URL (path); HttpURLConnection connection = (htt

Currently, Android has not recommended creating notification instances in the following ways: Notification Notification = new Notification (R.drawable.ic_launcher, "This is ticker text", System.currenttimemillis ()) ; It is best to use the following methods: Notification Notification = new Notification.builder (this) . Setcontenttitle (' This is title ') . Setcontenttext ("This is content") . Setsmallicon (R.drawable.ic_launcher) . Settic

The development of the Android process will encounter at least one main thread, also known as the UI thread, this thread is not allowed to block, or will error, such as the most common access to network resources, read and write files and other operations, these time-consuming operations can no longer use the main thread.
