Caution

This constant will be removed in the future version. Use Android.Content.PM.ServiceInfoFlags enum directly instead of this field.

Bit in #flags: If set, the service (which must be isolated) will be spawned from an Application Zygote, instead of the regular Zygote.

Remarks

Bit in #flags: If set, the service (which must be isolated) will be spawned from an Application Zygote, instead of the regular Zygote. The Application Zygote will pre-initialize the application's class loader, and call a static callback into the application to allow it to perform application-specific preloads (such as loading a shared library). Therefore, spawning from the Application Zygote will typically reduce the service launch time and reduce its memory usage. The downside of using this flag is that you will have an additional process (the app zygote itself) that is taking up memory. Whether actual memory usage is improved therefore strongly depends on the number of isolated services that an application starts, and how much memory those services save by preloading. Therefore, it is recommended to measure memory usage under typical workloads to determine whether it makes sense to use this flag.
