![]() “None”, to emulate a device without a camera.If you can configure a camera, your options are: Whether you can configure both front and back cameras, or just one, is indeterminate. In the “Advanced Settings” area, you can control whether or not the emulator emulates a device with a camera:ĪVD Configuration, Showing Camera Options You can also control whether the device starts up in portrait or landscape mode at the outside, by the toggle buttons labeled “Startup orientation”:ĪVD Configuration, Showing “Startup orientation” Options In the Android Studio AVD Manager, in the “Advanced Settings” area, there is an “Enable keyboard input” checkbox that determines whether hardware keyboard input is honored in the AVD or not:ĪVD Configuration, Showing “Enable keyboard input” Checkbox If you wish to switch your emulator to emulate a device with a physical keyboard - either “for realz” or just to simplify working with the emulator on your development machine - you can do so. However, this means that typing on your development machine’s keyboard will not work in EditText widgets and the like - you have to tap out what you want to type on the on-screen keyboard. Most Android devices do not have a physical keyboard, and so the emulator is set up to behave the same. The Android emulator can emulate devices that have, or do not have, a physical keyboard. “Auto” (the default) delegates the decision to the emulator itself, based on its own heuristics of what will work well.“Hardware” says to render the graphics using the GPU of your development machine.“Software” says to render the graphics purely within the emulator software.This setting is toggled within the AVD Manager, for new and existing AVDs, via the “Graphics” drop-down list in the “Emulated Performance” group: Also, their use might conflict with other things you might want to do - on Linux, using hardware GPU mode might break your ability to take screenshots, for example. Whether this will work or not for you will depend in part upon your graphics drivers of your development machine. By default, the emulator will use software-based rendering, without the GPU, which is slow in general and worse when running an ARM-based image. One way to speed up the emulator is to have it use the graphic card or GPU of your development machine to accelerate the graphics rendering of the emulator window. When defining an AVD, or editing an existing AVD definition, there are many configuration options at your disposal, beyond those that we saw in the earliest chapters of the book. Here, we will explore some more capabilities of the emulator, beyond the basics of being able to run your Android app. We set up the emulator and set up an AVD earlier in the book. ![]() However, nearly every developer winds up using the Android SDK emulator for at least some work. Some developers focus on using actual Android-powered devices for testing their Android apps.
