Re: [android-developers] Re: StackOverflowError in UI redraw

Ok thanks.
Now the good news is that when i changed my code to setText(getText(aResID).toString() + anotherString) i don't have any more the same trace (but as it was not easily reproductible, it is difficult to say it is completly solved).

The bad news is that when i add also these 2 following lines in my TabActivity.onCreate to change the tab color:

        tabHost.setBackgroundColor(Color.BLACK);
        tabHost.getTabWidget().setBackgroundColor(getResources().getColor(R.color.dark_blue));

I have now a systematic crash at startup :( (no mention of CharSequence in the backtrace)
Does changing the color has anything to do this layout nest level??

Particularly the "tabHost.setBackgroundColor(Color.BLACK);" seems to cause the crash.

You are using a CharSequence, I see that from your stack trace.

I have a similar modularity issue as you do.  Unfortunately, one of my
in-tab activity is also used standalone, so it's not most practical to
make it a View.  It's possible, but would involve some code
duplication.  Luckily, for me, removing a couple of layers combined
with the .toString() trick was enough to prevent the crash on 1.5.
