使用Jaybird和Android时出错(Error using Jaybird and Android)

 我用Firebird直接wifi连接在android上创建了一个应用程序。 有时我会收到此错误： 
 

 
 
 致命异常：AsyncTask＃4 java.lang.RuntimeException：在java.util.concurrent.FutureTask在android.os.AsyncTask $ 3.done（AsyncTask.java:200）执行doInBackground（）时发生错误$ Sync.innerSetException（FutureTask .java：274）java.util.concurrent.FutureTask的java.util.concurrent.FutureTask.setException（FutureTask.java:125），java.util.concurrent.FutureTask的$ Sync.innerRun（FutureTask.java：308）。在java.util.concurrent.ThreadPoolExecutor.runWorker（ThreadPoolExecutor.java:1088）的java.util.concurrent.ThreadPoolExecutor $ Worker.run（ThreadPoolExecutor.java:581）上运行（FutureTask.java:138）java.lang.Thread .run（Thread.java:1019）由org.firebirdsql.jdbc.AbstractConnection.isValid（AbstractConnection）中的org.firebirdsql.gds.impl.wire.AbstractJavaGDSImpl.iscDatabaseInfo（AbstractJavaGDSImpl.java:518）引起的java.lang.NullPointerException .java：594）at br.com.controlemesa.banco.DBFBConnect.disconnect（DBFBConnect.java:61）at br.com.controlemesa.banco.DBFBConnect.spListaMesas（DBFBCon） nect.java:170）at br.com.controlemesa.activities.MesasActivity $ PopulaGridMesas.doInBackground（MesasActivity.java:193）at br.com.controlemesa.activities.MesasActivity $ PopulaGridMesas.doInBackground（MesasActivity.java:1）at android .os.AsyncTask $ 2.call（AsyncTask.java:185）at java.util.concurrent.FutureTask $ Sync.innerRun（FutureTask.java:306）... 4更多 
 

 

 还有其他人收到此消息吗？ 我怎么能阻止这个？ 

I created an application on android with Firebird direct wifi connect. Sometimes I get this error:
