  Audio API in Android development

Mobile devices of the first generation were not capable of playing any sounds except monophonic ringtones. Today any smartphone platform supports playback, record and to some extent manipulation of digital sound, often up to CD quality.Android is no exception to that. Even older 1.5 devices can do a lot of things with digital audio. However, due to lack of guidance, a developer who is doing his first audio feature might miss some of the available API facilities, or might choose the approach that...

  Understanding abstract interface in Java

Have you read about an interface declaration as public abstract interface InterfaceName in Java? At the first glance, is it a weird declaration? Why should we declare an interface as abstract? For example, we may see below code in some projects: public abstract interface MyInterface { public void check(); public abstract boolean check(boolean really); } Actually here abstract is redundant, an interface is implicitly abstract, we no need to put an abstract in front of interface. But it do...

  HTTP is not a transport protocol, HTTP is not RPC

Recently there was a question on the forums asking why we encourage usage of HttpRequestMessage<T> / HttpResponseMessage<T> in the signature of a web api implementation. The point made in the post is that if you have an ICalculator contract which your API implements, then it’s violating SOC / inappropriate to have those messages as params and in the contract. The argument is valid when looking at HTTP from the standpoint of an RPC mechanism, which is actually a quite co...

  Different ways to pass query parameters in EmberJS

In EmberJS, one could pass query parameters when retrieving resources with store.query() method. But what if there is a requirement that one wants to pass query parameters when calling store.findRecord()? Or there is a requirement that one wants to pass query parameters to a relationship when calling model.get('hasManyAttribute') in a RESTful style? In this post, we will explain how these can be achieved. In the store.query() case, one could easily pass the query parameters by passing ...

  Bytes Matter

I love to profile applications, because I always learn something that surprises me. Initial Profiler Surprise: Client Side Case in point, I was recently profiling our Android application, the Famigo Sandbox. This app sends a lot of data back and forth with our API, as we try to determine which of the apps on your phone are safe for your kids. I always assumed that, if app performance suffered during some of the ...

  Different types of keystore in Java -- Windows-MY

Windows-MY is a type of keystore on Windows which is managed by the Windows operating system. It stores the user keys and certificates which can be used to perform cryptographic operations such as signature verification, data encryption etc. Since it's a kind of native keystore, Java doesn't have a general API to access it. To help Java applications access the keys and certificates stored in Windows-MY keystore, Java provides a separate API -- SunMSCAPI. The SunMSCAPI provider is ...

  Mastering Async/Await in JavaScript: A Comprehensive Guide with Examples

As a veteran JavaScript developer, I have seen the evolution of JavaScript's asynchronous programming landscape. From callbacks to promises and now async/await, JavaScript has come a long way in making it easier to handle asynchronous operations in a clean and readable manner. In this article, we will delve into the world of async/await and explore why it has become a popular choice for handling asynchronous operations in JavaScript. We will cover the basics of async/await, its syntax, and how i...

  What we still can’t do client-side

With the rise of all these APIs and the browser race to implement them, you’d think that currently we can do pretty much everything in JavaScript and even if we currently can’t due to browser support issues, we will once the specs are implemented. Unfortunately, that’s not true. There are still things we can’t do, and there’s no specification to address them at the time of this writing and no way to do them with the APIs we already have (or if there is a ...

  Java SynchronizedList and Iterator

While reading some material about concurrency, I come up with some writing about using SynchronizedList wrap about normal List to enable synchronization.   But one interesting thing is http://docs.oracle.com/javase/7/docs/api/java/util/Collections.html#synchronizedList%28java.util.List%29   It says     It is imperative that the user manually synchronize on the returned list when iterating over it:     1   List list = Collections.synchronizedList(new A...
