Android Manifest features and permissions.

The Android Manifest is an XML file that contains important metadata about your Android app. It includes details such as the app's package name, version number, and components like activities, services, and broadcast receivers. One critical aspect of the Android Manifest is the declaration of permissions. Permissions are used to control access to various system resources, like the camera, microphone, or Internet connectivity. Apps must declare the permissions they need within the Manifest file, and users must grant them explicitly when installing or running the app. Without proper permission declaration and management, your app could be rejected from the Google Play Store or seen as a security risk to users. Additionally, more recent versions of Android have required apps to ask for some permissions at runtime, which means that you must build in support for requesting and obtaining permission dynamically. Overall, the Android Manifest plays a crucial role in defining your app's capabilities and ensuring that it operates securely within the Android platform.

It is organized alphabetically by file extension, making it easy to find the corresponding MIME type for a particular file format.

List of DNS addresses

A DNS address list (sometimes referred to as DNS server list) is a collection of domain name system (DNS) server addresses. DNS is a system that translates domain names (such as www.example.com) into IP addresses that computers can understand. When you access a website, your computer sends a request to a DNS server, which returns the IP address for that website, allowing your computer to establish a connection. A DNS address list typically contains multiple DNS server addresses, which can provide redundancy in case one server fails or is unavailable. It can also be used to improve network performance by selecting the fastest available server. DNS address lists can be manually configured on a computer or obtained automatically from an internet service provider.
