1. A method comprising:

  • performing operations as follows on a processor of an application wrapper computer;

    decompiling executable code of an application package to provide a decompiled application package;

    tracing a plurality of operational flows through decompiled application code of the decompiled application package, each operational flow associated with at least one application programming interface (API) of the decompiled application package;

    identifying features of the application package based on content of the decompiled application package, by obtaining a manifest file from the decompiled application package, and determining resources of a host user device that the application package will use based on permissions contained in the manifest file for at least one API call of the API associated with a request by the application to access the feature;

    selecting a set of wrapper logic components from among a library of wrapper logic components based on the features of the application package by;

    determining, for each feature, a parameter value representative of a number of operational flows of the application package that contain an API call associated with a request by the application to access the feature; and

    excluding from the set of the wrapper logic components at least one of the wrapper logic components of the library that has a parameter value below a predetermined threshold;

    disassembling the decompiled application package to provide disassembled code;

    inserting wrapper program hooks into the disassembled code to provide modified disassembled code;

    assembling the modified disassembled code to provide modified assembled code; and

    combining the wrapper logic components of the set with the modified assembled code to form a wrapped application package comprising executable code from the modified assembled code and executable code from the wrapper logic components of the set that intercept calls by the executable code from the modified assembled code.
