In the top left window we can see a tab with the label “Devices". Here we can find all the devices/emulators that are “Online" and connected to Eclipse. Below each instance of the Emulator or device, we have all processes that are running in this instance, each process runs in its own Virtual Machine and we can identify them by the package name of the application it host. In the most-right column we find the ports where this VM are connected. And just in the left of the processes name, there is other number, this is the “Linux process ID". Every Linux process has its own unique identification, as Android is based on Linux kernell, we find the same process systems here.
In this same window, we find some icons in the top side of it.
From left to right.
--The “bug" icon, represents the debugger state. If its green, we are connected to the debugger and we can do debugging task. If it is red, we are disconnected from the debugger.
--The multiple-rows icon, just activates the “threads visualization", if we select a process and we click this icon, in the right panel, in the tab “Threads" we will see the info, state and actualization times of the threads running in this process.
--The bucket-like icon. Has more or less the same functionality than the “Update Threads" icon. In this case we update the heap memory usage of this process. Clicking on it we update this information in the right panel.
--The stop icon, is just as easy as, stop the selected process.
--And to finish talking about this icons, we find the “Get screenshot" icon, with this, we can have an instantaneous picture of our device/emulator screen.
