reusability

问题 I am a newbie in Android ! I have some huge problems with Android's SDK, as I'm developing an app that uses huge bitmaps (> 1200 * 1000) and the problem is during the app I need multiple layers/bitmaps of the same size (3-5 of them). The problem is memory heap is consumed very quickly on one of these allocations and OutOfMemory exception is triggered. The good part is that I don't need all of the bitmaps in the same time. I tried the recycle() method calling, although I understood it's

问题 I'm making an audio heavy page. I'm using the JavaScript audio element. The code looks like this: JavaScript: var x = new Audio("x.mp3"); var y = new Audio("y.mp3"); var z = new Audio("z.mp3"); function playMe(n){ n.play(); } HTML: <button class="button" onclick="playMe(x)")>Play</button> <button class="button" onclick="playMe(y)")>Play</button> <button class="button" onclick="playMe(z)")>Play</button> Some pages use up to 30 different audio files so this will consume a lot of bandwith.

问题 Before ASP.NET Core MVC, we would use RazorGenerator to compile views into assemblies, and we would reuse those views in another project, by introducing a custom ViewEngine that would load the view from the assembly instead of file-system. In ASP.NET Core MVC there is this concept of pre-compiled views and it works out of the box for version 2.0 and creates an assembly that by convention has the name of project_name.PrecompiledViews.dll . I have two problems though that I can't find an answer

问题 General problem I want to style reusable Angular components to match the style of the specific client project. I maintain the reusable components in a separate project and generate an npm package out of it. That package is published to a private NPM repository (Sinopia) and then installed into multiple client projects.
