更新:我搜索了这么多……我需要缓存键吗？？
最佳答案
您是否在 MainActivity 中实现了 InvalidateMemoryCache？阅读更多 https://github.com/luberda-molinet/FFImageLoading/wiki/Advanced-Usage#clear-cache-and-memory-considerations
public override void OnTrimMemory([GeneratedEnum] TrimMemory level)
{
FFImageLoading.ImageService.Instance.InvalidateMemoryCache();
GC.Collect(GC.MaxGeneration, GCCollectionMode.Forced);
base.OnTrimMemory(level);
}
public override void OnLowMemory()
{
FFImageLoading.ImageService.Instance.InvalidateMemoryCache();
GC.Collect(GC.MaxGeneration, GCCollectionMode.Forced);
base.OnLowMemory();
}
我认为，问题出在你的 base64 逻辑上，但让我们试试这个。
