This article mainly introduces how to use Android.mk template in Android related knowledge, content detailed and easy to understand, simple and fast operation, has a certain reference value, I believe everyone read this article how to use Android.mk template in Android will have some gains, let's take a look at it.

Android development Android.mk template example detailed explanation

1. How to automatically add a list of source files to compile

2. How to add third-party static library, dynamic library dependencies

3. How to construct a complete NDK engineering framework

Suppose our project depends on libmath.a, libjson.a, libffmpeg.so these third-party library files, the project contains the following modules: algorithm, core, network, utils, tests, each module has several.c/.h files, we want to compile the whole project into a dynamic library, and through the native_sdk.c function to provide a call interface to the Java layer.

Then, we can divide the jni directory of Android project as follows:

The corresponding Android.mk file is written as follows (Note: The project file can be viewed online in my Github (@Jhuster/Android) or downloaded in the attachment at the end of this blog post):
