The Online Android Emulator simulates Android devices to allow you to test a number of apps and Android API levels on your desktop without having to use the physical devices. Almost every function of a true Android device is offered by the emulator. Inbound calls and text messages may be simulated. The device’s location, distinct network speeds, hardware sensors and rotation and Google Play Store access, etc. can all be simulated.
Mobile Testing can be eased a lot by the use of Online Android Emulator. In some ways it is quicker and simpler to test your app on an emulator than on a physical computer. You can pass information to the emulator more quickly, for instance, than to a USB linked device. The emulator includes preconfigured settings for different Android phones, tablets, operating systems and Android TV.
Each instance of Online Android Emulator utilizes the Android Virtual Device (AVD) to define the version of Android and its hardware features. To test your app efficiently, you should generate an AVD, which models each device that is supposed to operate your app. The AVD Manager is used for creating and managing AVDs.
Each AVD works as an autonomous device, with its own user information, SD card or personal storage. The emulator stores user information, SD card information, and cache in an AVD-specific folder by default. When the emulator is launched, it loads AVD folder user information and SD card information.
A snapshot is a stored image of an AVD which preserves the entire state of the device at time of saving — including OS settings, application and user data. You can return to a saved system status by loading a snapshot whenever you choose, save time to wait for the virtual device operating system and applications to rebook and save the efforts to resume testing on the app. In contrast to booting a virtual machine from a powered-off state, the Start of a snapshot is very much like waking a physical machine out of a sleep state. A fast-boot snapshot and a range of general snapshots can be available for each AVD.
The easiest way to use snapshots is by using quick-boot snapshots. By default, each AVD can save a quick-boot snapshot automatically when it leaves and loads from a fast-boot snapshot when starting. When an AVD begins, it has to boot like powering on a computer. If Quick Boot is activated, all loads from the given snapshot will be loaded and the system will be returned to the saved region in that snapshot.
Snapshots are valid for the system image, AVD setup and emulator functions they are stored with. All the snapshots from the affected AVD get invalid when you make a difference in one of them. Any update to the Android Emulator, system image, or AVD settings resets the AVD saved state, so you need to boot in a resume fashion the next time you start the AVD. The Snapshots panel in the Extended Controls window of the emulator contains the most controls for saving, loading and managing snapshots.
Thus, we have seen the key details allied to the working of Online Android Emulator as well as how it assists in the process of Mobile testing. If for the next time you also want to perform testing, you can do so through these android emulators.
