A unique numerical value created when you create your Firebase project, available in the Cloud Messaging tab of the Firebase console Settings pane. The sender ID is used to identify each sender that can send messages to the client app.
Likewise, what is the FCM?
A futures commission merchant (FCM) is an entity that solicits or accepts orders to buy or sell futures contracts, options on futures, retail off-exchange forex contracts or swaps, and accepts money or other assets from customers to support such orders.
What is the use of GCM in Android?
Google Cloud Messaging (commonly referred to as GCM) is a mobile notification service developed by Google that enables third-party application developers to send notification data or information from developer-run servers to applications that target the Google Android Operating System, as well as applications or
XMPP (Extensible Messaging and Presence Protocol) is a protocol based on Extensible Markup Language (XML) and intended for instant messaging (IM) and online presence detection. It functions between or among servers, and facilitates near-real-time operation.
Firebase gives you complete control over authentication by allowing you to authenticate users or devices using secure JSON Web Tokens (JWTs). The custom JWT returned from your server can then be used by a client device to authenticate with Firebase (iOS, Android, web).
A token identifier is an integer that tells what type of lexeme has been identified in the input stream. Those identifiers can either be referred to a named constants that are prefixed with a so called token id prefix, or directly with a number or a character code.
Most apps need to know the identity of a user. Firebase Authentication provides backend services, easy-to-use SDKs, and ready-made UI libraries to authenticate users to your app. It supports authentication using passwords, phone numbers, popular federated identity providers like Google, Facebook and Twitter, and more.
An access token is an object that describes the security context of a process or thread. The information in a token includes the identity and privileges of the user account associated with the process or thread. The security identifier (SID) for the user's account. SIDs for the groups of which the user is a member.
1) API Tokens is a bit of a general term. Usually an API token is a unique identifier of an application requesting access to your service. Your service would generate an API token for the application to use when requesting your service. An API token is the form of authentication similar to a username/password.
Google handles the user authentication, session selection, and user consent. The result is an authorization code, which the application can exchange for an access token and a refresh token. The application should store the refresh token for future use and use the access token to access a Google API.
OAuth 2 is an authorization framework that enables applications to obtain limited access to user accounts on an HTTP service, such as Facebook, GitHub, and DigitalOcean. OAuth 2 provides authorization flows for web and desktop applications, and mobile devices.
Google APIs is a set of application programming interfaces (APIs) developed by Google which allow communication with Google Services and their integration to other services. Examples of these include Search, Gmail, Translate or Google Maps.
Google Places is the information that a search engine receives and uses when listing your business. A search engine will probably already have your business listed in results, but your Google Places page allows you to control what information Google has and presents to searchers about your business.
Android is developed by Google, but can also be used without any Google services. So the Android platform SDK can be used for developing Android applications. If you however want to use any Google services in your Android Application, you should use the Google API Java Client library.
Android is a mobile operating system developed by Google, based on a modified version of the Linux kernel and other open source software and designed primarily for touchscreen mobile devices such as smartphones and tablets.
Yes, Android is a free and open platform but Google imposes certain terms on phone and tablet manufacturers in return for key apps on that free operating system, says The Wall Street Journal. Android is free to device makers, but it seems there are a few catches.
The Android mobile operating system is free for consumers and for manufacturers to install, but manufacturers need a licence to install Gmail, Google Maps and the Google Play store - collectively called Google Mobile Services (GMS). Manufacturers can be refused a licence if they do not meet Google's requirements.
Google's Android mobile operating system has emerged to become a dominant force in the smartphone landscape. You see, there is Google Android, the project that Google builds and shares with its handset partners, then there is the Android Open Source Project (AOSP). The two are not exactly the same.
The official language for Android development is Java. Large parts of Android are written in Java and its APIs are designed to be called primarily from Java. It is possible to develop C and C++ app using the Android Native Development Kit (NDK), however it isn't something that Google promotes.
The Android Open Source Project (AOSP) is an initiative created to guide development of the Android mobile platform. The Android platform consists of the operating system (OS), middleware and integral mobile applications.
5 Answers. Just a little addition: Android Studio is based on a bare version of IntelliJ which is open source. The guys from Google added the Android taste on top of IntelliJ and release this under Apache 2 license which is also open source.
