The Android platform provides a framework API that applications can use to interact with the underlying Android system. The framework API consists of: A core set of packages and classes. A set of permissions that applications can request, as well as permission enforcements included in the system

Paytm All-in-One SDK provides a swift, secure, and seamless payment experience to your users by invoking the Paytm app (if installed on your user’s smartphone) to complete payment for your order. It enables you to accept payment via Paytm Wallet, Paytm Postpaid, Paytm Payments Bank, Saved Debit/Credit Cards, Net Banking, BHIM UPI, or EMI as available in your customer’s Paytm account. If the Paytm app is not installed on a customer's device, the transaction will be processed via web view within the All-in-One SDK.

The Google Analytics SDK for Android makes it easy for native Android developers to collect user engagement data from their applications. Developers can then use the Google Analytics reports to measure: The number of active users are using their applications. From where in the world the application is being used. Adoption and usage of specific features. Crashes and exceptions. In-app purchases and transactions. And many other useful metrics... The Google Analytics SDK also gives you the tools to monitor the success of mobile marketing campaigns. Connect user interactions with paid ads, Google Play downloads, and subsequent in-app usage and Ecommerce transactions. Google Analytics provides a powerful platform to measure and optimize all of your application marketing efforts.

Google Play services powers a broad set of SDKs on Android to help you build your app, enhance privacy and security, engage users, and grow your business. These SDKs are unique in that they only require a thin client library to be included in your app, as shown in figure 1. At runtime, the client library communicates with the bulk of the SDK's implementation and footprint in Google Play services.

Google Tag Manager enables developers to change configuration values in their mobile applications using the Google Tag Manager interface without having to rebuild and resubmit application binaries to app marketplaces. This is useful for managing any configuration values or flags in your application that you may need to change in the future, including: * Various UI settings and display strings * Sizes, locations, or types of ads served in your application * Game settings Configuration values may also be evaluated at runtime using rules, enabling dynamic configurations such as: * Using screen size to determine ad banner size * Using language and location to configure UI flags Google TagManager also enables the dynamic implementation of tracking tags and pixels in applications. Developers can push important events into a data layer and decide later which tracking tags or pixels should be fired. TagManager currently supports the following tags: * Google Mobile App Analytics * Custom Function Call tag

kObjects is a collection of small ("kilobyte") projects. Most of the projects are suitable or designed for the Java 2 Micro Edition (J2ME/MIDP).

The ksoap2-android project provides a lightweight and efficient SOAP client library for the Android platform. It is a fork of the kSOAP2 library that is tested mostly on the Android platform, but should also work on other platforms using Java libraries. It is still using Java 1.3 so should work fine on JavaME, Blackberry and so on.

kXML is a small XML pull parser, specially designed for constrained environments such as Applets, Personal Java or MIDP devices.

XmlPull project is dedicated to be a site for * for general Pull parsing promotion/education (including StAX) and in particular to contain easy-to-reuse samples and code fragments * a resource for discussing new ideas and concepts related to pull parsing * a java namespace (org.xmlpull.*) and project location of a free implementation of the event object API and Factories, based on the StAX XMLStreamReade and old Common API for XML Pull Parsing * as java namespace and project location of StAX and XmlPull based utilities and samples such as: - providing an XML stream from a DOM tree - a DOM builder - SAX adapter - JUnit tests * as a maintenance resource for the existing XmlPull interface
