makefile – vs

Exception or error:

I’m a little fuzzy about the use of &

I’ve tried reading APPLICATION-MK.HTML & ANDROID-MK.HTML in the documentation that comes with NDK, but still confused about the purpose of two makefiles.

I’ll be really grateful to anyone who could help me understand this.

How to solve:

Each module requires one and only one If all you ever have is one module in your native application, the is redundant (however there are a few things that can only be controlled by the if you veer from default behavior). However, if you have many modules, ergo many files in your project, than the can be useful for providing application-wide settings that apply to ALL modules.


Quote from docs/OVERVIEW.html

While an file describes your modules to the build system, the file describes your application itself. See the
docs/APPLICATION-MK.html document to understand what this file allows you
to do. This includes, among others:

  • The exact list of modules required by your application.

  • The CPU architecture(s) to generate machine code for.

  • Optional information, like whether you want a release or debug
    build, specific C or C++ compiler flags and others that should
    apply to all modules being built.

This file is optional: by default the NDK will provide one that simply
builds all the modules listed from your (and all the makefiles
it includes) and target the default CPU ABI (armeabi).

hope it helps
