"Unopened exception thrown by the finalizer" when opening MapActivity

Question

I have these lines in my code:

// 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; } 

When the application launches the string tabHost.addTab(tabspecWhereAmI); , I get the following error only in LogCat, and the program starts without problems:

This exception occurs before the onCreate(...) ActWhereAmI . My problem is similar to this question: Do not throw exception thrown by finalizer

Why am I getting this error and how to solve it?

Answer 1

Are you doing something related to db? It almost looks like the action that the DB stuff does closes the cursor (manually or automatically) and then tries to do something with it in finalize () or that the cursor closes with Android OS.

In case No. 2, this may mean that you may need to manually close the cursor. If so, but if you need to open an action, consider reopening / closing it in onResume / onPause or onStart / onStart

Someone else said that it could be because you are trying to open two of them at the same time.

Answer 2

This has something to do with Cursor in onStop() or onDestroy() . You can call it by calling closeTab() or closeAllTabs() .

Hope this helps.

Answer 3

Remember to close the cursor as soon as you finish the cursor before the application moves on to another action.
