Compile libmad for Android

 

1. Download libmad source code

 

2, in the directory C: \ cygwin \ home \ Administrator \ android-ndk-r4b-windows \ android-ndk-r4b \ samples \ create directory jni, and libmad source code decompress to this directory, so mad. h directory is: C: \ cygwin \ home \ Administrator \ android-ndk-r4b-windows \ android-ndk-r4b \ samples \ libmad \ jni \ libmad-0.15.1b

 

3. Create Android. mk content in the jni directory:

 

Include $ (all-subdir-makefiles)

 

4, in the jni/libmad-0.15.1b directory to establish Android. mk, content:

 

LOCAL_PATH: = $ (call my-dir)

 

 

 

Include $ (CLEAR_VARS)

 

 

 

LOCAL_MODULE: = mad

 

LOCAL_ARM_MODE: = arm

 

LOCAL_SRC_FILES: = bit. c decoder. c fixed. c frame. c huffman. c layer12.clayer3. c stream. c synth. c timer. c version. c

 

LOCAL_CFLAGS: =-DHAVE_CONFIG_H-DFPM_ARM-ffast-math-O3

 

 

 

Include $ (BUILD_SHARED_LIBRARY)

 

5. Start Cygwin to the directory samples.

 

6. Run: ../ndk-build NDK_PROJECT_PATH = $ NDK_ROOT/samples/libmad
