Mobile service applications

A mobile device configured for providing a mobile application, the mobile application including a plurality of service applications, the mobile device comprising:

• circuitry configured to:
• determine a dependency tree for the mobile application, wherein:
• the dependency tree defines startup and shutdown dependencies among the plurality of service applications;
• and
• each service application is configured to execute within a separate thread upon startup;
• and
• determine to execute a first service application of the plurality of service applications;
• determine, based on the dependency tree, one or more parent service applications of the first service application;
• startup the one or more parent service applications based on the dependency tree in one or more threads;
• and
• subsequent to starting up the one or more parent service applications, startup the first service application in a first thread separate from the one or more threads;
• and
• subsequent to starting up the first service application, execute the first service application within the first thread.

A method for a mobile device to provide a mobile application, the mobile application including a plurality of service applications, the method comprising:

• determining, by circuitry of the mobile device, a dependency tree for the mobile application,
• wherein the dependency tree defines startup and shutdown dependencies among the plurality of service applications, and
• wherein each service application is configured to execute within a separate thread upon startup;
• determining, by the circuitry, to execute a first service application of the plurality of service applications;
• determining, by the circuitry and based on the dependency tree, one or more parent service applications of the first service application;
• starting up, by the circuitry, the one or more parent service applications based on the dependency tree in one or more threads;
• subsequent to starting up the one or more parent service applications, starting up, by the circuitry, the first service application in a first thread separate from the one or more threads;
• and
• subsequent to starting up the service application, executing, by the circuitry, the first service application within the first thread.
