As a Java-based developer, it is easy to initially learn about Android development. Some of my colleagues are learning java, and I am interested in Android development, I started to learn about it and made a simple and practical small application in less than a month. There may be many people who will ask what are the gaps between Android Developers and those who

Step 1: Create an android project named updatedemo. The code structure is shown in:
Step 2: Create an updatemanager. Java class to update the software module. The Code is as follows:
