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.

Create an OOM Monitor session

        ROomMonitorSession ioomMonitorSession;
CleanUpClosePushL(ioomMonitorSession);
User::LeaveIfError(ioomMonitorSession.Connect());

Set the priority for the application to High .

        iOomMonitorSession.SetOomPriority(ROomMonitorSession::EOomPriorityHigh);
DoCriticalBackgroundProcessingL();

Close the session.

        iOomMonitorSession.Close();
