还是发现有OOM的问题

GoogleCodeExporter commented 8 years ago

首先非常感谢作者对gifview再次进行了优化,感谢作者付出的努
力。不过我在调试过程中发现对于某些图片还是存在OOM的问��
�。

不知道作者有没有考虑过对gif图片的解码部分用c来处理呢。�
��反编译了快图,发现它的gif图片显示部分是用jni来处理的,图�
��解码是用c写的。它的解码速度很快,也没有OOM的问题。不过�
��对NDK没有啥研究,只能抛砖引玉了。

以下是异常信息,附件中是调试用的gif图片:

我这边用你的图来测试，没有出现OOM，不知道你那边是什么��
�的环境。
至于解码的c处理部分，我已经完成了用c对gif来解码，因为这
段时间比较忙，等我自己测试过后会放出来

避免OOM，你可以在以下方法中加入这几行就可以了（在GifView.
java中）
private int getCurrentFrame() {
        // 如果当前帧不为空的话，销毁当前帧里的bitmap对象
        if (null != currentImage) {
            currentImage.recycle();
            currentImage = null;
        }
        // 后面的不变
    }

附件中是加这几行与不加这几行之间的区别

附加上我测试用的gif文件，1.7M的gif图片，不算小

@  xiang....@gmail.com   

下面的方法 什么时候调用呢？
private void getCurrentFrame() {
        // 如果当前帧不为空的话，销毁当前帧里的bitmap对象
        if (null != currentImage) {
            currentImage.recycle();
            currentImage = null;
        }
        // 后面的不变

    }
