说明

之前的工程都是在Eclipse下演示的，随着Android Studio的普及，我这里也开始使用Android Studio写Demo，虽然细节导入jar包和so库的过程可能不太一样，但是整体的流程是一样的。

将jar包和so库导入Android Studio工程

将jar包copy到libs目录下

在main目录下创建jniLibs目录，将so文件copy过来

添加网络权限

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET"/>

初始化

在清单文件中application标签下添加name属性

android:name=".InitApplication"

初始化

package com.example.kongqw.kqwspeechcompounddemo;

import android.app.Application;
import android.widget.Toast;

import com.iflytek.cloud.SpeechConstant;
import com.iflytek.cloud.SpeechUtility;

/**
 * Created by kongqw on 2015/8/29.
 */
public class InitApplication extends Application {
    @Override
    public void onCreate() {
        Toast.makeText(this, "InitApplication", Toast.LENGTH_LONG).show();
        // 应用程序入口处调用,避免手机内存过小,杀死后台进程后通过历史intent进入Activity造成SpeechUtility对象为null
        // 如在Application中调用初始化，需要在Mainifest中注册该Applicaiton
        // 注意：此接口在非主进程调用会返回null对象，如需在非主进程使用语音功能，请增加参数：SpeechConstant.FORCE_LOGIN+"=true"
        // 参数间使用“,”分隔。
        // 设置你申请的应用appid
        StringBuffer param = new StringBuffer();
        param.append("appid=55d33f09");
        param.append(",");
        param.append(SpeechConstant.ENGINE_MODE + "=" + SpeechConstant.MODE_MSC);
        // param.append(",");
        // param.append(SpeechConstant.FORCE_LOGIN + "=true");
        SpeechUtility.createUtility(InitApplication.this, param.toString());

        super.onCreate();
    }
}
