Increasing the Priority of a Third-Party Application

This section describes how a third-party application can increase its OOM priority by using OOM Monitor APIs.

Third-party applications that needs to be running all the time can increase their priority to High from the default level (Normal). By increasing the priority, applications can protect itself from being closed by the OOM Monitor. For example:

  • IP Phone application receiving IP calls

  • Instant Messaging application receiving messages

are applications which listens for events from the network all the time.

  1. Create an OOM Monitor session 
    ROomMonitorSession ioomMonitorSession;
CleanUpClosePushL(ioomMonitorSession);
User::LeaveIfError(ioomMonitorSession.Connect());
  2. Set the priority for the application to High . 
    iOomMonitorSession.SetOomPriority(ROomMonitorSession::EOomPriorityHigh);
DoCriticalBackgroundProcessingL();
  3. Close the session. 
    iOomMonitorSession.Close();
