毕加索创作OutOfMemoryError

Question

我们正在使用毕加索在我们的应用程序中加载所有的图像，从小的头像到大的全屏图像，我们每天每10个活跃用户就会收到1个这样的错误。毕加索的缓存正在填满，但我们的理解是，它应该保持自己。

我们的日志表明，在高端设备(Galaxy S4)上加载大型全屏图像(1080x1920)和大型头像(720x720)时，这些错误最常见，但偶尔也会在小型头像(135x135)上发生。

Answer 1

我也遇到过同样的问题，其中一个临时解决方法是

<application
    ...
    android:largeHeap="true">

到目前为止，我还没有找到另一个解决方案(也许我搜索得还不够)。但很多人都对毕加索有好感。

Answer 2

加载图片时调用fit()吗？我怀疑这是我的问题，我假设图像是用毕加索自己采样的，但你仍然需要告诉它这样做。
