Asynchronous SQLite sample with dot42?

阅读更多关于 Asynchronous SQLite sample with dot42?

问题 I've been testing dot42 and so far great, but I see that there aren't any SQLite samples. Im not sure if I should implement a ContentProvider (as some android articles suggests) or if I could use the async / wait implementation of dot42 in order to perform a query asynchronously and show the result on a ListView. Any advice ? Thanks in advance Roygar 回答1: Here is a code sample that retrieves contacts from a SQLite database asynchronously using the async/await implementation of dot42. I

How do you implement callbacks in C# using async/await with Xamarin for Android? And how does this compare to standard Java programming for Android? gregko With Xamarin for Android version 4.7, at the time of this writing still in publicly available beta, we may use .NET 4.5 features to implement 'async' methods and 'await' calls to them. It always bothered me, that if any callback is needed in Java, the logical flow of code in a function is interrupted, you have to continue the code in the next function when the callback returns. Consider this scenario: I want to collect a list of all

Does anyone have benchmarks (code & results) comparing performance of Android apps written in Xamarin C# and Java? [closed]

I came across Xamarin claims that their Mono implementation on Android and their C# compiled apps are faster than Java code. Did anyone perform actual benchmarks on very similar Java and C# code on different Android platforms to verify such claims, could post the code and results? Added June 18, 2013 Since there was no answer and could not find such benchmarks done by others, decided to do my own tests. Unfortunately, my question remains "locked" so I cannot post this as the answer, only edit the question. Please vote to re-open this question. For C#, I used Xamarin.Android Ver. 4.7.09001
