Dynamic class loading

摘要

Approaches are described for loading code on an electronic device by altering the behavior of an application's classloader. The application can be received at an application store, and the application can be injected with code. The application can be downloaded from the application store and installed on the portable computing device or other device, and in response to starting the application, the injected code can be configured to select classes or other application code, and modify a classpath associated with the application to reference the selected classes or application code.

1. A computer implemented method, comprising:
under the control of one or more computer systems configured with executable instructions, receiving an application at a server associated with an electronic application store; introducing classpath modifying code into the application, the classpath modifying code, when executed by a computing device, causing the computing device to:
generate a classpath associated with the application to reference one or more classes; and be configured to retrieve the one or more classes to enable at least one function of the application without requiring an update of the application.
