Developer can also start the AVD Manager from the command line by calling the androidtool with the avdoptions, from the/tools/ directory.The New Virtual Machine wizard is opened. Look for the 'Signing & Capabilities' tab.The easiest way to create an AVD is to use the graphical AVD Manager, which developer launch from Eclipse by clicking Window > AVD Manager. Select your project in the Xcode Project Navigator, then select your main target (it should share the same name as your project). Type the following in your command prompt to install and launch your app on the device: npx react-native run-android. To list the emulators you have.An Android Virtual Device (AVD) is an emulator configuration that lets developer model an actual device by defining hardware and software options to be emulated by the Android Emulator.3. This emulator not only works best on PC but also on Mac.

For example, developer can define whether the device has a camera, whether it uses a physical QWERTY keyboard or a dialing pad, how much memory it has, and so on. A hardware profile: Defines the hardware features of the virtual device. QEMU is a free and open source software.Developer can also create AVDs on the command line by passing the androidtool options. QEMU requires Mac OS X 10.

If application declares a uses-library element in its manifest file, the application can only run on a system image in which that external library is present. Forward-compatibility testing ensures that, when users who have downloaded application receive a system update, application will continue to function normally. Developer should create at least one AVD that uses a target whose API Level is greater than that required by application, because it allows developer to test the forward-compatibility of application. The API Level of the target is important, because application will not be able to run on a system image whose API Level is less than that required by application, as specified in the minSdkVersion attribute of the applicationвЂ™s manifest file. To thoroughly test application, developer should create an AVD for each general device configuration (for example, different screen sizes and platform versions) with which application is compatible and test application on each one.Keep these points in mind when developer are selecting a system image target for AVD:

Creating an AVDDeveloper can create as many AVDs as developer would like to test on. When developer start the AVD Manager in Eclipse or run the androidtool on the command line.From the main screen, developer can create, delete, repair and start AVDs as well as see the details of each AVD. An AVD is a device configuration for the Android emulator that allows developer to model different configurations of Android-powered devices. Usually, developer must create such an AVD using an Add-on component for the AVDвЂ™s platform (for example, the Google APIs Add-on contains the Google Maps library).The AVD Manager is an easy to use user interface to manage AVD (Android Virtual Device) configurations.

The Create New AVD dialog appears. Click New to create a new AVD. In the Virtual Devices panel, youвЂ™ll see a list of existing AVDs. In other IDEs: Navigate to SDKвЂ™s tools/directory and execute the androidtool with no arguments. In Eclipse: select Window > AVD Manager, or click the AVD Manager icon in the Eclipse toolbar.

Default value is вЂњyesвЂќ.Whether the device has a QWERTY keyboard. Default value is вЂњyesвЂќ.Whether there is a trackball on the device. Default value is вЂњ96вЂќ.Whether there is a touch screen or not on the device. Hardware optionsIf developer are creating a new AVD, developer can specify the following hardware options for the AVD to emulate:The amount of physical RAM on the device, in megabytes. Be sure to define a target for AVD that satisfies applicationвЂ™s Build Target (the AVD platform target must have an API Level equal to or greater than the API Level that application compiles against).AVD is now ready and developer can either close the AVD Manager, create more AVDs, or launch an emulator with the AVD by selecting a device and clicking Start. Developer can also add specific hardware features of the emulated device by clicking the NewвЂ¦ button and selecting the feature.

Default value is вЂњyesвЂќ.Whether there is an accelerometer in the device. Default value is вЂњyesвЂќ.Whether the device can run on a battery. Default value is вЂњnoвЂќ.Whether there is a GPS in the device. Default value is вЂњyesвЂќ.Whether the device has a camera. Default value is вЂњyesвЂќ.Whether there is a GSM modem in the device.

Default value is вЂњ160вЂќ.The androidtool lets developer manage AVDs on the command line. Default value is вЂњyesвЂќ.Sets the generalized density characteristic used by the AVDвЂ™s screen. Default value is вЂњyesвЂќ.Whether we use a /cache partition on the device. Default value is вЂњyesвЂќ.Whether the device supports insertion/removal of virtual SD Cards. Default value is вЂњyesвЂќ.Whether the device can play audio.

The target ID is an integer assigned by the androidtool. Developer can use any name developer want for the AVD, but since developer are likely to be creating multiple AVDs, developer should choose a name that lets developer recognize the general characteristics offered by the AVD. Developer can specify other options on the command line also, such as the emulated SD card size, the emulator skin, or a custom location for the user data files.HereвЂ™s the command-line usage for creating an AVD: android create avd -n -t. HereвЂ™s an example of the command output: Available Android targets: id: 1 or 'android-3' Name: Android 1.5 Type: Platform API level: 3 Revision: 4 Skins: QVGA-L, HVGA-L, HVGA (default), HVGA-P, QVGA-P id: 2 or 'android-4' Name: Android 1.6 Type: Platform API level: 4 Revision: 3 Skins: QVGA, HVGA (default), WVGA800, WVGA854 id: 3 or 'android-7' Name: Android 2.1-update1 Type: Platform API level: 7 Revision: 2 Skins: QVGA, WQVGA400, HVGA (default), WVGA854, WQVGA432, WVGA800 id: 4 or 'android-8' Name: Android 2.2 Type: Platform API level: 8 Revision: 2 Skins: WQVGA400, QVGA, WVGA854, HVGA (default), WVGA800, WQVGA432 id: 5 or 'android-9' Name: Android 2.3 Type: Platform API level: 9 Revision: 1 Skins: HVGA (default), WVGA800, WQVGA432, QVGA, WVGA854, WQVGA400 Creating AVDsIn addition to creating AVDs with the AVD Manager user interface, developer can also create them by passing in command line arguments to the androidtool.Open a terminal window and change to the /tools/directory, if needed.To create each AVD, developer issue the command android create avd, with options that specify a name for the new AVD and the system image developer want to run on the emulator when the AVD is invoked.

If developer want to use the default hardware emulation options for the AVD, just press the return key (the default is вЂњnoвЂќ). Do developer wish to create a custom hardware profile If developer want to set custom hardware emulation options for the AVD, enter вЂњyesвЂќ and set values as needed. Android 1.5 is a basic Android platform. HereвЂ™s an example that creates an AVD with name вЂњmy_android1.5вЂќ and target ID вЂњ2вЂќ (the standard Android 1.5 system image in the list above): android create avd -n my_android1.5 -t 2If the target developer selected was a standard Android system image (вЂњType: platformвЂќ), the androidtool next asks developer whether developer want to create a custom hardware profile. Developer should do this before developer run the android create avdcommand.When youвЂ™ve selected the target developer want to use and made a note of its ID, use the android create avdcommand to create the AVD, supplying the target ID as the -targument.
