Method and apparatus for extracting mobile application suitability features for a mobile business application
Application compatibility testing for mobile applications enables enterprises to improve the extraction of mobile application suitability features (MASFs) from an App using techniques other than reading the package's manifest. In addition to performing dependency analysis in the open package format context, embodiments of the invention interpret the analysis results in the context of mobile devices where, in addition to binary, i.e. go/no go, OS compatibility, there is compatibility testing for other suitability metrics, such as enterprise policy compliance and device capability and/or compliance. A MASF results dictionary keeps track of the various identified hardware and software interfaces of the App.
1. A computer system for extracting mobile application suitability features for a mobile application, comprising:
a processor;
a storage device, coupled to the processor, and storing a mobile application suitability features (MASF) dictionary comprising a reference set of suitability features, their detectable signatures, and their disposition;
the storage device further storing code which, when executed by the processor, enables the computer system to perform a method comprising:
referencing said mobile application suitability features dictionary;
extracting MASFs from a manifest of said mobile application;
extracting library-related MASFs from main executables of said mobile application by parsing the main executables and identifying library links indicative of a resource usable by said mobile application;
extracting resource related MASFs from peripheral device files of said mobile application, the peripheral device files being configured to access at least one of resources on peripheral devices and system resources; and
the storage device further storing a mobile application suitability features results dictionary, and code which, when executed by the processor, updates the mobile application suitability features results dictionary with said extracted MASFs and their properties,
wherein said mobile application suitability results dictionary accumulates an aggregate set of said extracted MASFs and their properties.
2. The system of claim 1 , wherein said manifest directly declares required resources of said mobile application; and
wherein extracted MASFs from said manifest include features having any of a disposition “requires,” “uses,” “non-localized,” and “localized”.
3. The system of claim 1 , further comprising inferring resource or functionality of said mobile application based on said library's resources or functions.
4. The system of claim 1 , further comprising:
using additional resources in said mobile application package to identify language localization resources for said mobile application and to determine an extent of localization support.
5. The system of claim 1 , further comprising:
comparing an enterprise policy specified by a user against a feature set extracted from said main executables and application functionality inferred from said libraries that are required by said mobile application to determine if said mobile application is compliant with said policy.
6. The system of claim 1 , wherein said mobile application suitability features results dictionary comprises any of a manifest entry, an MASF, feature disposition, a binary entry, and a resource entry.
7. A method for extracting mobile application suitability features for a mobile application, comprising:
providing a mobile application suitability features (MASF) dictionary comprising a reference set of suitability features, their detectable signatures, and their disposition;
providing a manifest analyzer executable by a processor that references said mobile application suitability features dictionary to extract MASFs from a manifest of said mobile application;
providing a main executable library link analyzer executable by the processor that references said mobile application suitability features dictionary to extract library-related MASFs from main executables of said mobile application by parsing the main executables and identifying library links indicative of a resource usable by said mobile application;
providing a resource analyzer executable by the processor that references said mobile application suitability features dictionary to extract resource related MASFs from peripheral device files of said mobile application, the peripheral device files being configured to access at least one of resources on peripheral devices and system resources;
wherein for a given mobile application package, each of one or more of said manifest analyzer, said main executable library link analyzer, and said resource analyzer interrogating a different subsection of the mobile application package to extract said MASFs;
providing a mobile application suitability features results dictionary for receiving said extracted MASFs and their properties from said manifest analyzer, said main executable library link analyzer, and said resource analyzer; and
said mobile application suitability features results dictionary accumulating an aggregate set of said extracted MASFs and their properties.
8. The method of claim 7 , further comprising:
said main executable library link analyzer inferring resource or functionality of said mobile application based on said library's resources or functions.
9. The method of claim 7 , further comprising:
said resource analyzer using additional resources in said mobile application package to identify language localization resources for said mobile application and to determine an extent of localization support.
10. The method of claim 7 , further comprising:
one or more of said manifest analyzer, said main executable library link analyzer, and said resource analyzer comparing an enterprise policy specified by a user against a feature set extracted from said main executables and application functionality inferred from said libraries that are required by said mobile application to determine if said mobile application is compliant with said policy.
11. The method of claim 7 , wherein said mobile application suitability features results dictionary comprises any of a manifest entry, an MASF, feature disposition, a binary entry, and a resource entry.
