Create an Android virtual device (AVD)

The full name of the AVD is Android virtual device, which is an Android-run emulator that is recognized as an Android simulator. To build the Android to run, the AVD must be created, and a lot of running projects can be configured on each AVD.

First we select the window and then select the Android SDK and Avdmanager, and a window appears after clicking, such as:

Here we explain that the middle should be empty, because I have created two, so there will be two. Then click on the New button on the right to the window that appears:

AVD Name: Is the name of the virtual machine to be filled out, this oneself casually named on the line, to pure English and digital composition
Device: Here are the devices to choose the analog, the general Choice 3.2*QVGA (ADP2) (320*480:MDPI) This is analog a phone model, because it is the simulator, personal advice to choose 320*480,
Target: is the choice simulator to touch your Android version, see the main development of the building what version of the system, the current 4.0 is the mainstream select Android4.0.3 API 15
Cpi/abi: Is the simulator of the CPU model, where the choice of Arm,arm is the phone's CPU model
Keyboard and Skins: can be checked by default, indicating what element is displayed on the emulator's interface, which does not affect the simulator, because Android is a touchscreen
Front camera and Back camera: Indicates whether to simulate the front and rear camera, here is not recommended, sometimes choose the simulator will not open, here is the default of none can be
RAM: Indicates emulator memory, 512M or 1024M or higher, but Google requires no more than 1024,1024m will not start the problem
VM Heap: Is the maximum memory space allocation for each application of the simulator the larger the simulator, the faster it will run, the default
Internal Storage: The size of the analog mobile phone chip storage capacity, that is, the mobile phone "memory" is actually equivalent to the computer's hard disk, generally used to store the operating system, so personal advice here to more than 1024M, Because more than 4.0 of the operating system by default requires more than 512M of memory, this memory of course the bigger the better
SD Card: Selected on the size, this is the default directory in the automatic creation of a simulated SD card file, the size of the SD card is optional, you can not fill out the non-use of SD card
Snapshot: Indicates that the simulator does not use the boot, this feature may cause the simulator to not start, but the check-in simulator will be faster to start, but the personal advice is not checked
Use Host GPU: Indicates whether the PC's GPU simulates the phone's graphics card, it is recommended not to tick, some video cards can not start the emulator after simulation.

Once you've set the options, click OK.

Add: Snapshot means "snapshot". The ability to save the state of the AVD when it is closed, and then the next time it starts, shows the state of the last shutdown, similar to the caching mechanism. Using the use Host GPU makes the AVD resolution higher and larger and better to look at. Using "Keyboard" will be you can use your own hardware keyboard input. With "Skin", there will be more control interfaces, as shown in.
