android  请问语音识别Demo里ActivityMain除了跳转界面是不是还有其他的作用啊，

我把Demo里的语音识别代码全部复制了，还是报错

    android:name="com.baidu.speech.APP_ID"

    android:value="8015241" />

    android:name="com.baidu.speech.SECRET_KEY"

    android:value="FW475sGvpAVzUpmo8O8fyQt4jrhYuhIO" />

     android:name="com.baidu.speech.VoiceRecognitionService"

     android:exported="false" />

    android:name="com.baidu.lbsapi.API_KEY"

    android:value="Hue8uAkvra9YRICzF9N4ceDrPgEKhnjW" />

这几个我也配置了

报错：java.lang.SecurityException: Permission Denial: starting Intent { act=com.baidu.action.RECOGNIZE_SPEECH cmp=com.baidu.speech.recognizerdemo/com.baidu.voicerecognition.android.ui.BaiduASRDigitalDialog (has extras) } from ProcessRecord{42708e78 15503:com.mc.parking.client/u0a407} (pid=15503, uid=10407) not exported from uid 10415
