GraphicsLayer + SimpleFillSymbol issue in 1.1.1 SDK

StephenQuan — Sun, 17 Jun 2012 23:34:15 GMT

I'm encountering a polygon drawing issue with the automatic black outline you get when using SimpleFillSymbol on the GraphicsLayer.

When using Australian coordinates (Elmore, Victoria, Australia) the automatically black outline does not follow the perimeter of the polygon. Instead, it is incorrectly drawn to infinity.

When using American coordinates (e.g. ESRI campus) the black outline does follow the perimeter of the polygon.

So, this feels like there's an arithmetic issue in the 1.1.1 SDK. The same code works correctly in the 1.0.1 SDK.

The following code example is a modified Hello World Map sample with code for GraphicsLayer with the Polygon and SimpleFillSymbol. Both Elmore and Redlands coordinates are provided with the Redlands commented out.

These devices DO reproduce the issue:

Samsung Galaxy Tab 10.1, Android 3.2

Samsung Gio, Android 2.2.1

These devices DO NOT reproduce the issue:

Samsung Nexus S, Android 4.0.4

Samsung Tab 7, Android 2.3.3

HTC Desire, Android 2.2

Emulator with GPU emulation, Android 4.0.3

**EDIT** When testing on the older 1.0.1 SDK the issue doesn't occur on the all of the above devices.

This appears to be fixed in the 2.0.0 SDK.
