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

Question

我正在尝试在 onDraw 方法中使用 android Movie class 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 Huawei Ascend P7 和 Samsung galaxy a5 上，应用程序在 movie.draw(canvas, x, 0) 上崩溃，异常：

A/libc(23632): Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1), thread 23632

知道 movie.draw 在这些设备上有什么问题吗？

更新：以下是完整的堆栈跟踪

执行代码movie.draw()后发生致命信号错误，其余为movie.draw()之前行的执行堆栈跟踪。

Answer 1

我可以通过禁用 android 硬件加速来解决问题：

android:hardwareAccelerated="false"

Answer 2

和Sultana, but surprisingly here's didn't work for me while this one did. it's 一样您仅在使用此行绘制电影的特定视图上禁用硬件加速器。

view.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
