Android realizes the automatic update function of app

Now the general Android software needs to be updated constantly. When you open an app, if there is a new version, it will prompt you that there is a new version to be updated. This function is realized by the applet.

The feature of the applet is that when there is an update, a prompt box will pop up. Click OK to create a progress bar for download in the notification. Click Cancel to cancel the update.

The following is the detailed code:

1. Create layout file notification_ Item.xml, which is used to generate a progress bar and download icon in the notification bar.

2. Create appcontext class, which inherits from application.

3. Create the configuration file class config.java and define some version related constants in this class

4. Write the update service class updateservcie.java

5. Write the activity class updateactivity

6. Add permissions and statically load the service (load in the configuration file).

Registration service

The complete androidmanifest.xml file is as follows:

This is the end of the encoding.
