'Uncaught exception thrown by finalizer' when opening MapActivity

StackOverflow https://stackoverflow.com/questions/12931876

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 runs the line tabHost.addTab(tabspecWhereAmI); I get the following error only in LogCat and the program runs without any problem:

This exception occurs before the onCreate(...) method of ActWhereAmI. My problem is similar to this question: Uncaught exception thrown by finalizer

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

Was it helpful?

Solution

Are you doing anything db-related? It almost sounds like either the activity that's doing DB stuff has closed the cursor (manually or automatically) and then tried to do something to it in finalize(), or that the cursor is being closed by the Android OS.

In case #2, it may mean that you might have to manually close the cursor. If that's the case but if you need the activity open, consider reopening/closing it in onResume/onPause or onStart/onStart

Someone else mentioned that it might be because you are trying to open two of them at the same time

OTHER TIPS

This is somehow related to Cursor in onStop() or onDestroy(). You can invoke it by calling to closeTab() or closeAllTabs().

Hope this will help.

Remember to close the cursor once you are done with the cursor before application traverse to another activity.
