Patent ID: 10191728

Abstract:
A mobile device based on an Android™ operating system configure to reduce the size of downloaded Android™ application packages. The mobile device comprises a storage device configured to store data, transceiver circuitry for downloading an Android™ application package, and a package manager. The package manager analyzes resources in the downloaded Android™ application package; identifies unnecessary resources that are not suitable for use by the mobile device; deletes the unnecessary resources; generates from the remaining resources an optimized Android™ application package having a smaller size than the downloaded Android™ application package; and stores the optimized Android™ application package in the storage device under the same name as the downloaded Android™ application package. The package manager also identifies an original security certificate in the downloaded Android™ application package; and generates from the optimized Android™ application package a new security certificate. The package manager uses the original security certificate and the new security certificate to download an updated version of the Android™ application package.
