Marshmallow Version Permissions ModificationThe Android privilege system has always been the primary security concept because these permissions are only asked once during installation. Once installed, the app can access everything in the right without the user's knowledge, and the average user rarely has to look at the list of permissions when it's installed, not to get a deeper understanding of the risks a

, but for the vast majority of ordinary users, I'm afraid no one knows how to verify that the permissions the application requires are reasonable, and in most cases the user will grant the required permission directly. Therefore, developers need to strictly follow the principle of least privilege when applying for or setting permissions. Automatic static analysis and code verification Design a tool that automates the analysis of application features, analyzes the functionality of the applicati

For those who are unable to use Android smartphones for their eyesight, hearing or other physical reasons, Android offers accessibility features and services to help these users operate devices more simply, including text-to-speech, haptic feedback, gesture manipulation, Trackball and handle operation.

Android Service Security0x00 Popular Science A Service is an application component that has no interface and can run on the background for a long time. other application components can start a service and run on the background, even if the user switches to another application, it will continue to run. in addition, a component can be bound to a service for interaction, even if the interaction is inter-process communication. for example, a service may

Android Broadcast Security0x00 Popular Science Broadcast Recevier is a component that focuses on receiving and processing Broadcast notifications. Many broadcasts originate from system code, such as notifying time zone changes, low battery, taking a picture, or changing language options. Applications can also be broadcast-for example, to notify other applications that some data has been downloaded and is available. An application can have any number

intent is filtered out (the object classes without naming targets ). An explicit intent is always the target that can be submitted to it, no matter what it contains. In this case, the filter does not work. However, an explicit intent can be submitted to this component only when it can pass a filter of the component.Each task that a component can do is divided into different filters for each aspect presented to the user. For example, the main activity in the example notepad application contains

By implementing an Android application to monitor both of these permissions, the same log output module is used for processing, so that the behavior information detected in both detection modes can be integrated into aTo facilitate future analysis.
