Cuttlefish to other devices" tabindex="-1">Compare Cuttlefish to other devices</h2> <h3 id="cuttlefish_and_android_emulator" data-text="Cuttlefish and Android Emulator" tabindex="-1">Cuttlefish and Android Emulator</h3> <p>There are many similarities with the <a href="/docs/setup/test/avd">Android Emulator</a>, but Cuttlefish guarantees full fidelity with Android framework (whether this is pure AOSP or a custom implementation in your own tree). In real-world application, this means that you should expect Cuttlefish to respond to your interactions at the OS level just like a physical phone target built with the same customized or pure Android OS source.</p> <p>The Android Emulator has been built around the use case of making app development easy, and it contains many functional hooks to appeal to the use cases of the Android app developer. This may present challenges if you want to build an emulator with your customized Android framework. If you need a virtual device that will be representative of your custom platform/framework code or tip-of-tree Android, then Cuttlefish is an ideal virtual option. It is the canonical device for representing the current state of AOSP development.</p> <h3 id="cuttlefish_and_physical_device" data-text="Cuttlefish and physical device" tabindex="-1">Cuttlefish and physical device</h3> <p>The primary differences between a Cuttlefish virtual device and your physical device are at the hardware abstraction layer (HAL) level, as well as any software that interacts with any custom hardware. Except for hardware-specific implementations, you should expect functionally equivalent behavior between Cuttlefish and a physical device.</p> <h2 id="how_can_cuttlefish_help" data-text="How can Cuttlefish help?" tabindex="-1">How can Cuttlefish help?</h2> <p>You can interact with Cuttlefish just like you would with any other Android device that you might use for debugging. It will register itself as a normal device via adb and you can interact with it like a physical device via remote desktop. The use cases are broad and can span app testing, custom system build testing and more.</p> <p>Because Cuttlefish strives for full framework fidelity, it can be used for functional testing of your framework or apps where there are no physical hardware dependencies that are impossible to emulate.</p> <h3 id="how_is_cuttlefish_commonly_used_for_testing_today" data-text="How is Cuttlefish commonly used for testing today?" tabindex="-1">How is Cuttlefish commonly used for testing today?</h3> <p>Some common applications of Cuttlefish for testing include:</p> <ul> <li>CTS</li> <li>Framework compliance</li> <li>Continuous integration testing</li> <li>Custom test suites</li> </ul> <h2 id="can_i_host_cuttlefish_in_the_cloud" data-text="Can I host Cuttlefish in the cloud?" tabindex="-1">Can I host Cuttlefish in the cloud?</h2> <p>Yes, Cuttlefish natively supports Google Cloud and support for other cloud platforms is planned.</p> <h2 id="get_started" data-text="Get started" tabindex="-1">Get started</h2> <p>For guidance on creating a Cuttlefish instance based on AOSP, see <a href="/docs/devices/cuttlefish/get-started">Use Cuttlefish</a>.</p> </div> <devsite-thumb-rating position="footer"> </devsite-thumb-rating> <div class="devsite-floating-action-buttons"> </div> </article> <devsite-content-footer class="nocontent"> <p>Content and code samples on this page are subject to the licenses described in the <a href="/license">Content License</a>.
