Android页面在图像下载期间崩溃
Android页面在图像下载期间崩溃
提问于 2015-10-15 15:48:39
我是一个极端的Android / Java新手，正在开发我的第一个android应用程序。
我有一个从php/mySQL页面下载数据并在屏幕布局上显示数据的页面。数据将包含某些字段:标题、摘要、照片等。“照片”字段是存储在网上的图像的URL。
当照片链接字段为空时，页面似乎正常工作。当图像是一个很小的图像时，页面似乎工作得很好。但是当图像文件更大时，应用程序就会崩溃。
本页的完整代码如下所示，因为我不知道这段代码的问题在哪里！

你有一个内存不足的错误，我想你正在下载一个大的图像。我更希望你使用这 library.Its，既棒又容易使用。这个库下载图片并放入您想要的device.If的缓存中，详细说明如何使用，请随意编写。

正如其他人所指出的，这次崩溃似乎与内存管理有关。
我发现可以通过添加一个属性来处理这个问题：
android:hardwareAccelerated="true"作为清单中的活动标记。
有谁能评论一下，这是否是解决这一问题的合法途径？

当您下载图片时会出现这个问题，并且在下载了一些图像之后，没有剩余的内存分配给您的应用程序。有各种各样的图像加载库，使您的工作更容易：壁画，毕加索，滑行等。
- 我建议您通过Facebook查看图像管理库，这是相对于其他图像加载库来说非常棒和成熟的壁画。
- 壁画有
SimpleDraweeView作为自定义图像视图，它支持Rounded Corners and Circles链接，支持动画(.gif，.webp)以及普通图像(.jpg，.png)。 - Fresco用3层架构(
BITMAP_MEMORY_CACHE、ENCODED_MEMORY_CACHE和DISK_CACHE)处理图像的所有缓存。它还减少了OOM(内存不足)问题。当视图中的图像超出屏幕时，它会自动回收位图，从而释放内存。
可以通过在清单中添加android:largeHeap="true"来增加分配给应用程序的内存。
注意:为您的应用程序增加heap并不是理想的解决方案。
这是谷歌的摘录，
然而，请求一个大堆的能力只适用于一小部分应用程序，这些应用程序可以证明需要消耗更多的RAM (如大型照片编辑应用程序)。千万不要仅仅因为内存用完而请求大堆，并且需要快速修复--只有当您确切地知道分配内存的位置和必须保留内存的原因时，才应该使用它。然而，即使你确信你的应用程序可以证明你的大堆是正确的，你也应该避免在任何可能的程度上请求它。使用额外的内存将越来越不利于整个用户体验，因为当任务切换或执行其他常见操作时，垃圾收集将花费更长的时间，而系统性能可能会更慢。
