The majority of your testing is for correctness issues (not performance) and the majority of your code is probably not dealing with hardware specific issues.Use an emulator for the following reasons: do your designed interactions work for a user walking around using your app one handed with just their thumb alone?įor all other testing, which as part of your edit-compile-debug cycle normally takes at least 80% of your time, you’d want to use an emulator (barring other blocking issues or limitations with your emulator of choice). Purely evaluating the actual user experience in real-world situations, e.g.Ditto if you are trying to work around an OEM-specific bug. If what you are trying to test is the touch-responsiveness of your game, or the speaker quality for your media app, you will want to do that type of testing on the target devices. You want to measure the performance as your users see it. While an emulator can help you with correctness issues, it will never perfectly emulate the performance characteristics of your code running on the actual devices that you want to test against. Measuring the performance characteristics of your code.You definitely need to test against a device for the following scenarios which are unsuitable for any emulator: Having a great emulator to debug against doesn’t mean you don’t need a device, and having a device to debug against doesn’t mean you won’t benefit from a good emulator. We know that emulators can play a key part in the edit-compile-debug cycle (bigger part than devices) and we believe that you need an emulator like the one we are releasing today. For more, watch this video teaser or see it in action.īefore I walk you through using this new emulator, let’s talk about why we are building an emulator for Android – feel free to skip the next section to go to the interesting part □ The need for an emulator for Android**** You can also download the emulator without needing to install Visual Studio. When choosing one of those Android development options, Visual Studio will also install the brand new Visual Studio Emulator for Android to use as a target for debugging your app. Microsoft Visual Studio 2015 now has options for Android development: C++, Cordova, and C# with Xamarin. This post was updated in July 2015 to reflect the latest changes.
