LSPosed is an Android runtime hooking framework and in-memory code modifier. It functions as a system hooking tool that intercepts and modifies system and application methods in memory to change behavior without altering original installation files.
The project provides a standardized interface through the Xposed Module API, allowing for the development of plugins that alter the behavior of the Android operating system and installed applications.
The framework covers a range of capabilities including runtime function interception, Android system debugging, and application customization. These are enabled via bytecode manipulation, class-loader interception, and zygote-based process injection.
