Method to Modify Android Application Life Cycle to Control Its Execution in a Containerized Workspace Environment

摘要

Methods, devices, and systems are described to modify the life cycle of a Google Android® application, in its application manifest file and byte code, such that the execution of the application can be controlled via policies and security governed by a workspace application installed on an Android-based device. Dummy wrapper classes are inserted into the byte code for network and I/O system calls that call security code before calling the original classes.
