FLEX is a diagnostic framework designed for the inspection and modification of mobile applications during active execution. It provides a suite of tools that allow developers to explore the internal state of a running process, including its memory, class definitions, and object properties, without requiring a recompilation of the source code.
The tool distinguishes itself by enabling real-time interaction with the application environment. It facilitates dynamic user interface prototyping by allowing for the traversal and modification of visual hierarchies, as well as the direct manipulation of application settings and persistent user preferences. Furthermore, it provides deep visibility into the application sandbox, offering capabilities to browse, modify, and export local database records and file system contents.
Beyond state and UI inspection, the framework includes utilities for monitoring network traffic, allowing for the capture and analysis of request and response cycles. It also supports runtime exploration through memory scanning and the execution of arbitrary class methods, alongside input simulation tools that trigger touch events and keyboard shortcuts to validate interface navigation.
