内存泄露 #48

ztc464728422 · 2021-08-03T07:11:09Z

您好，您的开源框架是少数几个能在机顶盒上做复杂序列帧动画不卡的。
现在我遇到一个比较严重的内存泄露问题，我再一个页面中，不断的清除、新增多个 FrameAnimation控件播放多个序列帧，平均1小时左右，内存占用会在1分钟内突然持续大量增长，直到最终由decodeBitmap()触发OOM。OOM页面闪退后，泄露内存依然无法释放
。

#125006 java.lang.OutOfMemoryError
pthread_create (1040KB stack) failed: Try again

播放的图片序列帧，一般是7s 24fps 每张图大约100K左右，100-200张

ztc464728422 · 2021-08-03T07:59:59Z

泄露的内存为native内存

ztc464728422 · 2021-08-03T08:00:38Z

由于序列帧图片大小非降序，没有开启图片复用

在一个页面中，不断的清除、新增多个 FrameAnimation控件播放多个序列帧。
是指一直新增多个FrameAnimationView吗，还是一直使用同一个FrameAnimationView播放不同的动画呢。最好有简单的代码示例。

具体的场景是一组动态图播完一定时间后，清理，替换新一批动态图，每张动态图位置、大小都不同。

当前采用先移除后新增多个FrameAnimationView，完成2批动态图的切换。

加载代码如下：tvContent为FrameAnimationView

tvContent.setRepeatMode(FrameAnimation.RepeatMode.INFINITE);
tvContent.setScaleType(FrameAnimation.ScaleType.FIT_CENTER);
ArrayList fileslist = FileSort.orderByName(path);
if(fileslist == null) return;
ArrayList<FrameAnimation.PathData> t = new ArrayList<>();
for(String x : fileslist ){
FrameAnimation.PathData v = new FrameAnimation.PathData(x,FrameAnimation.getPATH_FILE());
t.add(v);
}
if(t.size()<100){
tvContent.setFrameInterval(80);
}else{
tvContent.setFrameInterval(40);
}
tvContent.setSupportInBitmap(false);
tvContent.playAnimation(t);

通过android 手机的测试，再手机中连续进行上述操作，1次在2小时后，1次再4小时，也都出现了app卡死的情况，通过bugly手机错误信息如下，并检测到此时存在大量线程，包括16个图片解码DecodeThread 线程：

我这边对log日志中的大量GC操作有些疑惑，不知道是否可能是产生上述异常的原因之一

关闭图片复用会导致内存抖动，频繁GC。

crash堆栈看起来跟这个库没有关系。
如果使用不同的FrameAnimationView有可能会导致pthread_create的OOM，每个FrameAnimationView都会创建一个线程池，动画结束30s后线程池中的线程才会释放。

以下两种基本确认为现在的主要报错信息，不过没有再看到内存出现明显增长了。
