android音频（三）——利用ndk直接编译faac和faad（续2）

step7 验证

1、在工程的主项目app下，编写java代码

app\src\main\java\com\thinking\maketest\Test.java

package com.thinking.maketest;/** * Created by Yu Yong on 2017/10/18. */public class Test {    static {        System.loadLibrary("com_thinking_faacd");    }    public static native void test();}//javah -d E:\AV-study\MakeTest\app\jni -classpath E:\AV-study\MakeTest\app\build\intermediates\classes\debug com.thinking.maketest.Test

app\src\main\java\com\thinking\maketest\MainActivity.java

package com.thinking.maketest;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;public class MainActivity extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        Test.test();    }}

2、在app项目下新建jni目录，编写C++验证程序

app\jni\com_thinking_maketest_Test.h

/* DO NOT EDIT THIS FILE - it is machine generated */#include <jni.h>/* Header for class com_thinking_maketest_Test */#ifndef _Included_com_thinking_maketest_Test#define _Included_com_thinking_maketest_Test#ifdef __cplusplusextern "C" {#endif/* * Class:     com_thinking_maketest_Test * Method:    test * Signature: ()V */JNIEXPORT void JNICALL Java_com_thinking_maketest_Test_test  (JNIEnv *, jclass);#ifdef __cplusplus}#endif#endif

app\jni\test.cpp

#include "com_thinking_maketest_Test.h"#include <faac.h>#include <faad.h>#include <android\log.h>JNIEXPORT void JNICALL Java_com_thinking_maketest_Test_test  (JNIEnv *, jclass){    faacEncHandle hEncoder;    faacEncConfigurationPtr pConfiguration;    __android_log_print(ANDROID_LOG_INFO, "yuyong", "faac test success");    NeAACDecHandle decoder = NeAACDecOpen();    NeAACDecClose(decoder);    __android_log_print(ANDROID_LOG_INFO, "yuyong", "faad test success");}

3、编写编译脚本

app\jni\Application.mk

APP_STL := gnustl_staticAPP_CPPFLAGS := -frtti -fexceptionsAPP_CFLAGS += -Wno-error=format-securityAPP_ABI := allAPP_PLATFORM := android-24

app\jni\Android.mk

LOCAL_PATH := $(call my-dir)include $(CLEAR_VARS)LOCAL_MODULE := faacLOCAL_SRC_FILES := E:\AV-study\MakeTest\faac\libs\$(TARGET_ARCH_ABI)\libfaac.soinclude $(PREBUILT_SHARED_LIBRARY)include $(CLEAR_VARS)LOCAL_MODULE := faadLOCAL_SRC_FILES := E:\AV-study\MakeTest\faad\libs\$(TARGET_ARCH_ABI)\libfaad.soinclude $(PREBUILT_SHARED_LIBRARY)include $(CLEAR_VARS)LOCAL_MODULE    := com_thinking_faacdLOCAL_SRC_FILES := test.cppLOCAL_C_INCLUDES += E:\AV-study\MakeTest\faac\jni\include \    E:\AV-study\MakeTest\faad\jni\includeLOCAL_LDLIBS +=  -llog -ldl -lzLOCAL_SHARED_LIBRARIES := faac faadinclude $(BUILD_SHARED_LIBRARY)

4、编译C++部分得到
