SIGSEGV in Canvas.drawColor about sgtpuzzles HOT 4 CLOSED

Two more reports last month. :-( Should take another look at this...

from sgtpuzzles.

Hey Chris, I ran into this too - at exactly the same point (canvas.drawColor(Color.WHITE) in my case).

It only happens to me under API level 7 - exact same code at API level 8 and above runs fine.

I reduced it down to the simplest test-case I could produce, and managed to figure out that the following code exhibits the crashing behaviour in API level 7 and below, but works fine in 8+:

Canvas _c = new Canvas();
_c.drawColor(Color.WHITE);

The following code does not crash in level 7 and below, or 8+:

Canvas _c = new Canvas();
Bitmap _b = Bitmap.createBitmap(350, 350, Bitmap.Config.ARGB_8888);
_c.setBitmap(_b);
_c.drawColor(Color.WHITE);

When you look at it like that, it seems fairly obvious that my problem lay in the fact that the canvas wasn't really initialised correctly (ie., it had no idea what size it was). Hope this is helpful to you.

Awesome, thank you! :-) I never even thought of trying this on lower API levels (silly, I know). This is very helpful and I will look into how we could be hitting this situation as soon as possible.

At some point I added a dummy bitmap to initialise the canvas with (GameView.java:85); we haven't had backing-less Canvases around for some time.
