推荐答案

通常是在动态壁纸选择器中旋转设备时发生的.我发现的唯一解决方案是捕获IllegalArgumentException并将其忽略.

This typically happens when you rotate the device in the live wallpaper picker. The only solution I've found is to catch the IllegalArgumentException and ignore it.

if (canvas != null) {
    try {
        holder.unlockCanvasAndPost(canvas);
    } catch (IllegalArgumentException e) {
        // Ignore weird bug when rotating in live wallpaper picker
    }
}
