Android:movie.draw上的0x00000000(代码= 1)处的致命信号11(SIGSEGV)

Question

我试图在onDraw方法中使用Android Movie类在ImageView中显示动画gif,如下所示:

   @Override
    protected void onDraw(Canvas canvas) {
        canvas.drawColor(Color.TRANSPARENT);
        super.onDraw(canvas);
        long now = android.os.SystemClock.uptimeMillis();
        if (movieStart == 0) {
            movieStart = now;
        }
        movie = getMovieFromGif();
        if (movie != null && movie.duration() > 0) {
            try {
                int relTime = (int) ((now - movieStart) % movie.duration());
                movie.setTime(relTime);

                float movie_height = convertDpToPixels(movie.height());
                float movie_width = convertDpToPixels(movie.width());

                float new_movie_height = movie_height;
                float new_movie_width = movie_width;
                float movie_ratio = movie_width / movie_height;

                if (new_movie_width > container_width) {
                    new_movie_width = container_width;
                    new_movie_height = new_movie_width / movie_ratio;
                }

                if (new_movie_height > container_height) {
                    new_movie_height = container_height;
                    new_movie_width = new_movie_height * movie_ratio;
                }

                float scale_x = container_width / new_movie_width;
                float scale_y = container_height / new_movie_height;

                scale_x = new_movie_width / (float) movie.width();
                scale_y = new_movie_height / (float) movie.height();

                canvas.scale(scale_x, scale_y);
                float x = 0;
                if ((float) this.getWidth() > new_movie_width) {
                    x = ((this.getWidth() - (movie.width() * scale_x)) / 2f)
                            / scale_x;
                }

                movie.draw(canvas, x, 0);
                this.invalidate();
            } catch (Exception ex) {
                Log.i("onDraw()", "Error: " + ex.getMessage());
            }
        }
}

代码在大多数设备上运行良好,但在华为Ascend P7和三星galaxy a5上,应用程序在movie.draw(canvas,x,0)上崩溃,但有异常:

A/libc(23632):0x00000000(代码= 1)处的致命信号11(SIGSEGV),线程23632

知道movie.draw在这些设备上有什么问题吗？

在执行代码movie.draw()之后发生致命信号错误,rest是在movie.draw()之前执行行的堆栈跟踪.

我能够通过禁用Android硬件加速来解决这个问题:
