android – 打开MapActivity时’终结器抛出未捕获的异常’

概述我的代码中有这些行： // create tab4intent = new Intent(this, ActWhereAmI.class) .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);tabspecWhereAmI = tabHost .newTabSpec("tab4") .setIndicator(Ut 我的代码中有这些行：

// create tab4intent = new Intent(this,ActWhereAmI.class)        .addFlags(Intent.FLAG_ACTIVITY_CLEAR_top);tabspecWhereAmI = tabHost        .newTabSpec("tab4")        .setIndicator(UtilitIEs.prepareTabVIEw(this,"where am I"))        .setContent(intent);tabHost.addTab(tabspecWhereAmI);public static VIEw prepareTabVIEw(Context context,String text) {        VIEw vIEw = LayoutInflater.from(context).inflate(                R.layout.tab_indicator,null);        TextVIEw tv = (TextVIEw) vIEw.findVIEwByID(R.ID.tabIndicatorTextVIEw);        tv.setText(text);        return vIEw;    }

当应用程序运行行tabHost.addTab(tabspecWhereAmI)时;我只在LogCat中得到以下错误,程序运行没有任何问题：

此异常发生在ActWhereAmI的onCreate(…)方法之前.我的问题类似于这个问题：Uncaught exception thrown by finalizer

为什么我会收到此错误,如何解决？

解决方法 你在做与db有关的事吗？它几乎听起来像正在执行数据库 *** 作的活动已关闭光标(手动或自动)然后尝试在finalize()中执行某些 *** 作,或者 *** 作系统正在关闭光标.

在#2的情况下,这可能意味着您可能必须手动关闭光标.如果是这种情况但是如果您需要打开活动,请考虑在onResume / onPause或onStart / onStart中重新打开/关闭它

其他人提到这可能是因为你试图同时打开其中两个
