在执行服务时没有响应
在执行服务时没有响应
提问于 2014-10-11 12:33:02
我正在尝试创建一个登录页面，并使用安卓的服务类在后台运行。但是我看不到我在代码末尾创建的菜单。当我在模拟器中运行该应用程序时，它的行为完全正常。但是在调试模式下，它会给出一个和错误，这意味着应用程序没有响应。我的应用程序，我认为崩溃是因为服务响应时间非常高，然后才完成oncreate方法。我怎么解决这个问题？这是我的密码。

尝试：
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
menu.add(0, SIGN_UP_ID, 0, R.string.sign_up);
menu.add(0, EXIT_APP_ID, 0, R.string.exit_application);
return true;
