部件代码:
private PrinterTask(Context context) {
this.mContext = context;
helper = new DaoMaster.DevOpenHelper(context, "pos-db", null);
db = helper.getWritableDatabase();
mDaoMaster = new DaoMaster(db);
mDaoSession = mDaoMaster.newSession();
mPrintDataItemDao = mDaoSession.getPrintDataItemDao();
mRequestDataItemDao = mDaoSession.getRequestDataItemDao();
}
//
public void startPrintThread() {
dataIsExist = true;
//
if (!threadIsRuning) {
thread = new Thread() {
@Override
public void run() {
super.run();
threadIsRuning = true;
List<PrintDataItem> list;
while (dataIsExist) {
list = mPrintDataItemDao.loadAll();
if (list != null && list.size() > 0) {
KLog.d("startPrintThread", String.valueOf(++count) + " " + String.valueOf(list.size()));
}
threadIsRuning = false;
}
};
thread.start();
}
当计数器达到约600000时,应用程序将在没有任何警告的情况下退出。然后logcat输出以下信息:
日志输出:
(1)Could not create epoll instance. errno=24
(2)CursorWindow(26673): Could not allocate CursorWindow of size 2097152 due to error -24

我能做什么来解决这个问题?我会非常感激!
