![]() In this example, the interface is fairly simple. The steps to call a Dependency Service are:Ĭreate an interface within the main/shared application for all of the possible calls that the application may need to make. This feature is called Dependency Services. Xamarin.Forms has a way to make native calls out on the device that the code is running on. He said, "It would bring things to life for me." I thought about it and wondered if Xamarin.Forms could really do this and if the underlying platforms would support such functionality. He played with it on his Samsung Galaxy S8 and responded that it would be really cool if a sound effect played when he pushed a certain button. I built a simple version of one of the ideas and asked him what he thought about it. We started brainstorming and we ran through a couple of ideas. I was recently talking with a friend of mine and the talk turned toward what would be a cool app that might be of interest but doesn't currently have a lot of competition in a certain segment. Clearly data on forms is a very common need and handles probably 75 percent to 100 percent of many applications' needs. Unfortunately, Xamarin.Forms is designed mostly for working with data on forms. Android has its API for playing audio, and the two APIs are not nearly the same. The problem with audio and video is that they are pretty much device-specific operations. ![]() Xamarin.Forms is a high-level, cross-platform toolkit that runs on a number of platforms. In this article, I'll look at exactly that: how to play audio in the background when the user touches/clicks on a button. We click on a link or button and the screen is typically taken over as some video shows up and the accompanying audio begins to play.įor Xamarin.Forms mobile developers, a related issue that might come up is how to play some audio to provide a sound effect in an app, and specifically how would you play it in response to something like a button press. We will taking your feedback into consideration and see if these are updates we are add to a future version.We all know how to enjoy audio and video on our phones, tablets and computers. Thank you for your feedback! We do appreciate providing us insight on your thoughts about the app. Idk, but it needs something.Īlmost a great app, but falls short of being useful. Perhaps being able to zoom in on the frequency spectrum to get to specific spots, or as Apple does, a low speed scrub as you move your finger further from the slider. Also it doesn’t make sounds while you’re sliding the slider. You have to settle for 18,342 and be grateful that you got that close, or maybe if you really want push the minus button 342 times to get to your goal frequency. You can also drag the slider but its nearly impossible to set it to 16,000 or 18,000 or 15,500, or anything specific. There’s a plus and minus button that moves up or down one single hz, which is practical at 60 hz, but silly at 16,237. Its almost impossible to choose a specific frequency on the high end. I love that it’s simple, but it’s a little bit too simple. Many of these features were from user requests, so please keep the feedback coming!
