APP_PROJECT_PATH := $(call my-dir)/project
APP_MODULES := wolf3d
In the preceding snippet,
APP_MODULES
is critical. It defines the name of the module and must match
the application folder (
Wolf3D
). At the end of the process, the output library name will be named
libwolf3d.so
.
The next folder we need is an application source folder:
Create
NDK_HOME\sources\Wolf3D
. This folder will contain the native code.
1.
Copy the contents from
ch06.Wolf3D.SW/native/gp2xwolf3d
into the
Wolf3D
folder created in step 1.
2.
Create
NDK_HOME\sources\Wolf3D\Android.mk
. This is the Makefile used for
compilation (see Listing A-2).
