Figure 2.5. Standalone SDK Manager After you install the packages, you‟ll have the latest SDK and be ready to develop apps. However, before our test drive app one more step is needed: setting up the emulators.
2.2. Installation of Emulators Emulators are software that mimics the behaviour of real devices. When we develop an app, we obviously won‟t have all the possible devices (Android phones, tablets, etc.) available at hand. Because of this, we run the apps on emulators for testing on various devices. Emulators are also called as “Android Virtual Devices (AVDs)” in Android Studio. When Android Studio is first installed, there is no default AVD. We need to create one before testing our apps. For this, select Tools Android AVD Manager as shown in Figure 2.6.
