Do you wish to conquer the Android world with your app development skills? If yes, then an Android development course is just what you need for guiding you in the right direction. The course will contain all the details about Android, coupled with adequate practical sessions. To begin with, fundamentals of Android architecture and application design need to be known
Learning Android increases the developer’s competency by allowing exposure to the Android app environment and Google web service. Several real time examples from the industry are shown by instructors. These examples are helpful for candidates while they work on live projects.
Android Virtual Device (AVD)
One of the technologies that need to be learnt by a developer during Android development is an AVD. The AVD is an emulator configuration which allows one to model a real device by defining software and hardware options which are emulated by the Android emulator. The AVD Manager can be operated from the Android Studio, which is commonly used by every Android app developer.
What does an AVD consist of?
An Android Virtual Device has the following components:
Hardware profile: It defines various hardware features of the AVD.
Mapping to a system image: It is possible to define what version of Android can run on the AVD. A standard Android platform or the system image with SDK add-on can be selected.
Other options: It is possible to specify the kind of emulator skin to be used with the AVD. One can also choose a specific SD card to be used with the virtual device.
Fixed storage area on the development machine: User data of the device (settings, applications etc) and SD card are stored here.
Based on the type of device to be modelled, any number of AVDs can be made. When launched, the AVD will look like a window having the emulated Android environment. For example, one can configure the AVD session to emulate a Google Nexus 7 device. New AVDs can be made and managed with the Android Virtual Device Manager, which can be used either in a command line mode or with a GUI.
Android Virtual Device is essential to understand the entire Android environment. Know more by taking up an Android development course.
