在一个特殊的Android应用程序中我需要制作一个声音播放几个小时并通过我的服务控制它的服务...但声音播放器的代码在我的服务类的任何方法中都不起作用：（（< / p>
我从“服务类”扩展的播放器类：
makeConnection()}
我的主要活动：
public class QueueManagerServices {
final static int MQOO_INQUIRE_TOTAL = CMQC.MQOO_FAIL_IF_QUIESCING | CMQC.MQOO_INPUT_SHARED | CMQC.MQOO_INQUIRE;
MQQueueManager queueManager = null;
String cluster = null;
MQQueue queue = null;
public String getcluster(String host, int portNo, String qMgr, String channelName){
try{
queueManager = makeConnection(host, portNo, qMgr, channelName);
queue = queueManager.accessQueue(queueName, MQOO_INQUIRE_TOTAL);
int MQCA_CLUSTER_NAME = 2029;
int MQ_CLUSTER_NAME_LENGTH = 48;
int[] selectors = new int[1];
int[] intAttrs = new int[1];
byte[] charAttrs = new byte[MQ_CLUSTER_NAME_LENGTH];
selectors[0] = MQCA_CLUSTER_NAME;
queue.inquire(selectors, intAttrs, charAttrs);
cluster = new String (charAttrs);
} catch (MQException e) {
System.out.println(e);
} finally {
if (queue != null){
queue.close();
}
if (queueManager != null){
queueManager.disconnect();
}
}
return cluster;
}
}
并显示......
