Example text

In case an application wants to start a Service in a different process, it may do so using the attribute android:process. If the value of this attribute starts with a colon (:), the Service starts in a new private process within the application. If the value starts with a lowercase, a new global process is created that is visible and accessible to all applications of the Android system. In the preceding example, the Service runs in its own global process. The application should have permissions to create such a process.

In this case, do not forget to call stopSelf() or stopService() to stop a Service from continuing to run in the background. [ 27 ] Application Building Blocks Binder Binder is the backbone of most of Android's IPC. It is a kernel driver and all calls to Binder go through the kernel. The messenger is based on Binder as well. Binders can be confusing to implement and should only be used if the Service caters to multiple applications running in different processes and wants to handle multithreading itself.

The main motivation behind Dalvik is to reduce memory footprint by increased sharing. The constant pool in Dalvik is thus a shared pool. It also shares core, read only libraries between different VM processes. Dalvik relies on the Linux platform for all underlying functionality such as threading and memory management. Dalvik does have separate garbage collectors for each VM but takes care of processes that share resources. Dan Bornstein made a great presentation about Dalvik at Google IO 2008. v=ptjedOZEXPM.
