Hello

I am using android game is being developed in the skia.

succeeded in developing android 2.3.
Galaxy nexus (android 4.0.2) An error occurred when running on.

From the stack trace below, it looks like your native code is directly linking against the system's version of skia.

This definitely isn't something you should do. The Skia binary interface is not stable and has been changing between platform releases, this is why it is not exposed through the NDK.

The breakage you're experiencing is a direct consequence of these changes.

I recommend that you link your own version of Skia into your application instead.

It's weird.
drawRectCoords () was without error proceed.
drawRect () always get an error

Looking at Skcanvas.cpp
void SkCanvas:: drawRectCoords (SkScalar left, SkScalar top, SkScalar
right, SkScalar bottom, const SkPaint & paint)
 {
   SkRect r;
   r.set (left, top, right, bottom);
   this-> drawRect (r, paint);
}
Are defined as:

android 4.0.2 did write a completely different skia engine?

Questions, please.
