Implementation is supplemental to your existing payment app, enabling you to take advantage of your user base.The payment app is launched as a modal, in context of the merchant website.
Checkout flow with platform-specific Google Pay app that uses Web Payments.Ĭompared to using just Android Intents, Web Payments allow better integration with the browser, security, and user experience: The API can also invoke platform-specific payment apps. The Payment Request API brings to the web a built-in browser-based interface that allows users to enter required payment information easier than ever before. Step 4: Verify the caller's signing certificate.Step 2: Let a merchant know if a customer has an enrolled instrument that is ready to pay.Step 1: Let merchants discover your payment app.Īn analysis in 2011 by researchers from The University of California at Berkeley found that Intents can pose a security risk, allowing attackers to read content in messages and to insert malicious messages between applications. Intents in one application can start particular activities in a different application, if the latter supports the message type of the Intent. The activities supported by an application are declared in a manifest, so that other applications can read what activities are supported. Īctivities in Android are defined as classes that control the life cycle of a task in the user interface. Although the concept was not new, the Android architecture doesn't require elevated privileges to access the components, which makes it an open platform. The concept was created as a way to allow developers to easily remix different apps and allow each type of task (called activity) to be handled by the application best suited to it, even if provided by a third party. For Dummies likens an Intent to flicking a switch: "Your intent is to turn on the light, and to do so, you perform the action of flipping the switch to the On position." Description Īn Intent is basically a passive data structure holding an abstract description of an action to be performed. Its most significant use is in the launching of activities, where it can be thought of as the glue between activities: Intents provide an inter-application messaging system that encourages collaboration and component reuse. An Intent is a messaging object which provides a facility for performing late runtime binding between the code in different applications in the Android development environment. An Intent in the Android operating system is a software mechanism that allows users to coordinate the functions of different activities to achieve a task.
