However, if you find that you need to control which process a certain component belongs to, you can do so in the manifest file. The manifest entry for each type of component element—activity, service, receiver, and provider—supports an android:process attribute that can specify a process in which that component should run. You can set this attribute so that each component runs in its own process or so that some components share a process while others do not. You can also set android:process so that components of different applications run in the same process—provided that the applications share the same Linux user ID and are signed with the same certificates. The application element also supports an android:process attribute, to set a default value that applies to all components. Android might decide to shut down a process at some point, when memory is low and required by other processes that are more immediately serving the user. Application components running in the process thats killed are consequently destroyed. A process is started again for those components when theres again work for them to do. When deciding which processes to kill, the Android system weighs their relative importance to the user. For example, it more readily shuts down a process hosting activities that are no longer visib
