Android重启应用程序崩溃：java.lang.InstanceionException:无法实例化类；没有空构造函数

我的Android应用程序在闲置12小时后重启时崩溃

正如崩溃日志告诉我的那样，我一直在尝试到处添加空构造函数，但仍然失败

以下是崩溃日志：

有人能给我一些线索吗

更新日期2014/10/15上午11:00:MenuFragmentAutoHighlighter.java

public class MenuFragmentAutoHighlighter {

public HomeActivity homeActivity;

public MenuFragmentAutoHighlighter(HomeActivity homeActivity)
{
    this.homeActivity = homeActivity;
}

public void tryHighlightMenuItemByBaseFragmentClass(Fragment fragment)
{
    if (homeActivity == null || homeActivity.mLeftMenuFragment == null)
    {
        return;
    }

        homeActivity.mLeftMenuFragment.setSelectedPreMenuItem(
                ContentFragmentHelper.MENU_HOME,
                null);
}
}

BaseSlideActivity的构造函数以及您发布的所有其他构造函数都不应为空，因为此类扩展了SlidingFragmentActivity。 您应该在其中以及扩展其他类的类的所有其他构造函数中添加一个调用：

super.CLASS_NAME(); //a call to the super class's empty constructor

---

post MenuFragmentAutoHighlighter类注意：无法实例化fragment com.bochk.com.BaseSlideActivity$12，意味着您可能有一个非静态的内部fragment类，如果是，您应该将其设置为静态并尝试一下。我在我的工作区中搜索过，但没有声明内部fragment类，既不是静态的，也不是静态的。BaseSlideActivity$12中的第13个匿名内部类（从0开始计数）是没有参数构造函数的片段。$12-这意味着公共MenuFragment mLeftMenuFragment；受保护的权利碎片Mrightmen碎片；是吗？？？对不起，它坏了。我早些时候尝试过这个解决方案，但没有明显效果。最终我将onCreatebundle重写为super.onCreatenull
