使用initialize()时，杜比音频API返回-1

Question

我无法获取通过API连接到设备的API。initialize()返回-1

下面是我得到的错误日志：

因为initialize()在绑定Dolby Service之前发生，所以它将返回-1。

确保在应用程序/游戏开始前的最后一行调用了initialize()

I/DSPluginJNI( 3346): [callMethodWithBoolReturn] java_rtn = 00000001  // initialize() is called
I/DSPluginJNI( 3346): [callMethodWithIntReturn] java_rtn = ffffffff
I/DsClientFactory( 3346): DsClient is: android.media.dolby.DolbySurroundClient
I/DsClient07Wrapper( 3346): onClientConnected v=DS version 0.7.0.0
I/DSJavaPlugin( 3346): Dolby client connected… // DsService is binded
