SHARED PREFERENCES IN A MULTI-APPLICATION ENVIRONMENT

摘要

Various aspects of the subject technology relate to a system configured to store preferences in a file that is accessible to other applications on a computing device. The preferences stored in the file may include application use preferences that specify an application to be launched and the conditions in which the application is to be launched. The system further includes features for protecting the preferences in the file from modification by unauthorized parties or applications.
