android - 打开 MapActivity 时出现“终结器引发的未捕获异常”

Question

我的代码中有这些行:

// create tab4
intent = 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 tabHost.addTab(tabspecWhereAmI); 行时，我仅在 LogCat 中收到以下错误并且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

为什么会出现此错误，我该如何解决？

Answer 1

你在做任何与数据库相关的事情吗？这几乎听起来像是正在执行数据库操作的 Activity 关闭了游标(手动或自动)，然后尝试在 finalize() 中对其执行某些操作，或者游标正在被 Android 操作系统关闭。

在情况 #2 中，这可能意味着您可能必须手动关闭光标。如果是这种情况，但如果您需要打开 Activity ，请考虑在 onResume/onPause 或 onStart/onStart 中重新打开/关闭它

有人提到可能是因为你试图同时打开其中两个
