starting with Android 2.0, a new activity ("Running Services" activity) was added to the settings. It is used to show the memory usage of each service process currently running and the approximate memory usage of the entire phone. You can enter the activity through setting->applications->running services. The Running Services interface is as follows:Figure 1:Running Services is primarily a list of services processes that are currently running.in Figure 1, we can see 3 services processes:Gtalkservice: It is part of the standard Google application suit; it is running in Google's "Gapps" process, which is currently using 6.8MB of memory. It's been running for 3 Hours 55分钟23秒. Activityservice: It is part of the phonebook reference, where the process currently uses 4MB of memory. It's been running for 3 hours, 55 minutes, 20 seconds.SoftKeyboard: It is part of the input method. The process where it is currently using 6,1MB memory it has run 4分钟43秒. When you click a services process, a confirmation dialog box will pop up that concludes the process. such as:Figure II:However, some services, such as the input method, must be run and cannot be stopped. For these services, click it to enter the appropriate management interface. (here, for the input method, is to enter the system Input method settings interface). at the bottom of the running Services screen is approximate memory usage for the entire phone:"AVAIL:38MB+114MB in 25" means that the system has 38MB of completely free memory and can also get 114MB of memory by killing 25 processes running in the background. "OTHER:32MB in 3 says" means that the current 3 non-killed processes occupy 32MB of memory (these processes are looked at as foreground and must be run)
