What's the purpose of a PID in Android?
A:
In Android, the PID is an integer value assigned to the process and is specified by the Process class. A PID is also commonly referred to as a process identifier.
The Process class also provides some methods to get information about processes. In particular, the methods getCpuTime and getZygotePid provide the information about the current running process.
A:
To sum up: PID is an "internal identifier" of the running app process. It is normally generated when the process starts (at least for Android 2.x, it's still a mystery to me what this is exactly in Android 1.x).
A:
PID stands for process ID. It is a unique identifier of your running process. This is a key used to know if an app has been running or not.
You can use this PID to track your app using logcat, grep, adb,...
1. Field of the Invention
The present invention relates to a method of forming an insulating film on a surface of a semiconductor substrate, and a semiconductor device.
2. Description of the Related Art
In recent years, a semiconductor device in which a transistor formed over a substrate having an insulating surface (also referred to as a thin film transistor (TFT)) is used as a switching element or the like is actively developed. As a material having semiconductor characteristics which is used for a semiconductor layer that constitutes a transistor, a metal oxide film and the like can be given. Transistors include a variety of structures according to their structure, and the structure of a transistor referred to as a “planar structure” in which a channel formation region is provided in a semiconductor layer which is formed over a substrate having an insulating surface and a source region and a drain region are provided so as to sandwich the channel formation region is known.
As a method for forming a transistor, there is a technique in which a semiconductor layer formed over a substrate having an insulating surface is used as an active layer, and the semiconductor layer is then subjected to patterning to thereby form a transistor. As a semiconductor layer used for a transistor, a silicon layer, a compound semiconductor layer formed using a silicon layer as an under layer, or the like is used.
