P/Invoke is a way of calling C/C++ functions from a .NET program. It’s very easy to use. This article will cover the basics of using P/Invoke.
Note: This tutorial will focus on Windows and thus use Visual Studio. If you’re developing on another platform or with another IDE, adopting the things in this article should be easy enough.
With the Android NDK Google lets us write C/C++ code for Android. I don’t like writing C/C++ code because it’s error-prone but sometimes there’s no other way.
Unfortunately (this is the “I don’t like this” part), debugging Android C/C++ code is terribly difficult. If you don’t have a week to get the debugging toolchain working, and if you only need some quick and temporary solution, logging may be an alternative.
The idea of CSS is to separate design from structure (which is represented by HTML). So much for the theory. In pratice, however, this doesn’t always work – or at least the solution isn’t very obvious.
One of the most prominent examples is the so called clearfix. It solves the floating elements problem (described below) but usually requires you to change your HTML code.
Fortunately, with LESS (a better CSS) this is no longer necessary.
Different IDEs create different project files. Now the question is:
Which project files should I check into my VCS and which not?
This is what this article is about.
Sometimes (often?) downloads in the Android SDK Manager are annoyingly slow. The problem is that downloads are done over HTTPS. HTTPS is more secure but also slower than HTTP. Fortunately, Google allows us to change this behavior.
