![]() I certainly expect a small ms loss for checking that many times, but I wouldn't expect it to be so noticeable. The argument ToneGenerator.TONEPROPBEEP must be specified for the beep sound type provided by the Android OS. Call supervisory tone, Call Waiting: CEPT, JAPAN: 425Hz, 200ms ON, 600ms OFF, 200ms ON. A beep sound can be generated and played using ToneGenerator.startTone (ToneGenerator.TONEPROPBEEP), which is an API for the media-related function of Android OS. Now hit on Sync now button and wait for the build to complete. Minimum volume setting, for use with ToneGenerator(int,int). It feels like if I edit my step for the while loop to something like 100, 250, or even 500 ms from 10 ms, it seems more responsive, but I'm grasping to understand why. This article will guide you through creating an android application using which you can. Any thoughts? Did I implement something in a screwy way? It's almost as if my Wait(2000) waits for ~3000 total milliseconds and I don't understand why. For example, Task.Delay(2000) vs Wait(2000) sees almost an entire second difference that I cannot explain. However, I'm noticing a significant difference between the time the app is paused when compared to Task.Delay(ms). PauseTokenSource pts = new PauseTokenSource() while (totalPausedMs < msToWait)įor the most part, it works as intended. Class Overview This class provides methods to play DTMF tones (ITU-T Recommendation Q.23), call supervisory tones (3GPP TS 22.001, CEPT) and proprietary tones (3GPP TS 31.111). Is there no safe way to do this seemingly simple task using Xamarin.Android? Task.Delay(ms) works astoundingly well unless the OS interrupts my app and then everything falls apart.``Īlright, I threw together a prototype method on my GameActivities that looks something like this: I am building this rom for my personal use and now i wanted to share with you guys. Tl:dr I'm making a game, I need to wait on occasion to allow animations and such to play out and let the player sit for a second or two, and I need to be able to pause this delay if OnPause() is called, resume the delay when OnResume() is called, and pick up where I left off. This Rom is base off the best features from CM10, Aokp and PA. One feature which i did not fiund on the Android 2.0 is the ability to send DTMF tones during a call using the contacts. Sure, I could check for if the state has been saved or something after every single delay, but that feels like a hack and makes me think I must be doing something wrong. ToneGenerator - Created my own little dialer activity and hooked up ToneGenerator calls in response to button clicks, but then found out that it only generates tones in the dialers earpiece and not on the receivers side. If that happens, the delay keeps happily ticking along, returning into a method that is now paused with a view that's been disposed. However, this is dangerous, at least it certainly is on Android, as there is no way to pause that wait should the OS interrupt your Activity to take a phone call or something. Open up your app-level Gradle file and add the below dependency there. I feel like I'm missing something, as I've seen many, many suggestions of using Task.Delay(ms) for waiting in a mobile application. Create a new application in android studio and name it Barcode Scanner.
