WinDeath on notifyDataSetChanged()

Question

Hi I have following problem:

data.clear();
data.addAll(datasource.getFilesInFolder());  //gets the data from Sqlite database
adapter.notifyDataSetChanged();

generates this logCat output :

 12-19 14:34:30.864: W/Binder(986): Caught a RuntimeException from the binder stub implementation.
 12-19 14:34:30.864: W/Binder(986): java.lang.NullPointerException

 12-19 14:34:30.864: W/InputMethodManagerService(757): Got RemoteException sending setActive(false) notification to pid 30040 uid 10174

This exception causes WIN DEATH...

Well I realized maybe it is the other way round, WIN DEATH causing this log output, because in log WINDEATH comes before this, then I have no idea why does windeath occur.

My adapter is extended BaseAdapter with nothing really special in it. Very strange is the following :

The mentioned piece of code is inside a custom listener which is triggered from another class. When I put the problematic part outside the listener it works well.

I does the Caught a RuntimeException from the binder stub implementation mean ? Can it be a problem with a database ? or maybe my custom listener ? Anyone has an idea what's wrong ?

Answer 1

I have seen various problems that have this issue when doing concurrent actions. See for instance this thread (fling + service) and this one (drawing on canvas from 2 threads).

You are talking about a custom listener in a different class, could it be that you are also doing several things at once?
