  • Publication number: 20120151446
    Abstract: Although a software developer writing software for a mobile device typically performs the development and some of the debugging of the application on a software development computer, the application also has to be debugged as it passes through the deactivate, terminate and reactivate states as it executes on the mobile device. To debug an application the developer can launch the debugger on the software development computer. The debugger can launch the application on the mobile device. If an event that terminates the application occurs, the debugger connection is terminated. In accordance with aspects of the subject matter disclosed herein, the debugger is automatically reattached to the restarted (activated) application. Reattaching the debugger automatically to the restarted application allows the developer to debug the mobile device application as an application passing through multiple states rather than debugging multiple instances of an application.

  • Publication number: 20100023563
    Abstract: An aspect of the present invention stores files of a source directory in a target directory. In an embodiment, a unique identifier is generated for each of the files and a new location and a new name are generated for the file. The new location represents the specific sub-directory of the target at which the file is stored. The file is stored at the new location with the new name. Such storing in a new location with a new name can be advantageously used to address various issues in corresponding environments. In one environment, the target directory is stored in an embedded system, with limited resources and the source directory contains several files with substantial overlapping names (which can require substantial resources to search for a specific file). The unique identifiers are generated according to media transfer protocol (MTP), which generates an object identifier for each of the files/directories, etc.
