Android studio整合百度語音識別api
阿新 • • 發佈：2019-01-11
今天 專案中要用到語音功能，所以看了下百度語音api
1，根據百度語音開發文件，建立應用，下載相應的jar包，新增到你的應用
2，清單檔案配置資訊，
<uses-permission android:name="android.permission.RECORD_AUDIO" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<meta-data android:name="com.baidu.speech.APP_ID" android:value="xxxxxxx" /> <!-- 請填寫應用實際的API_KEY --> <meta-data android:name="com.baidu.speech.API_KEY" android:value="xxxxxxxxxx" /> <!-- 請填寫應用實際的SECRET_KEY --> <meta-data android:name="com.baidu.speech.SECRET_KEY" android:value="xxxxxxxxx" />
3 ,把drawable和raw下的資源全部複製到你的專案，注意：如果缺少資源會報錯
4 ，把so檔案複製到jnilibs目錄，這點很重要，我也是看下面這我博主文章才覺得這個問題

4，按照官方api程式碼編寫，根據自己的需求寫佈局，貼上demo程式碼

因為官方提供的是eclipse 環境demo，所以只要注意 3 ,4兩點，就很簡單了
