Question

我有一个活动和4个标签活动。在每个标签活动中我有画廊，网格布局，当我从标签活动回到我的主要活动时，我得到outofMemory异常。在我的所有标签活动中我有很多images.I已经从5天开始了。请帮助我。我的logcat是：

提前感谢。

查看开发者网站的Managing Bitmap Memory文章。

对于API＆lt; = 10：

在Android 2.3.3（API级别10）及更低版本上，建议使用recycle（）。如果您在应用中显示大量位图数据，则可能会遇到OutOfMemoryError错误。 recycle()方法允许应用程序尽快回收内存。

警告：只有在确定不再使用位图时才应使用recycle（）。如果您调用recycle（）并稍后尝试绘制位图，您将收到错误：“Canvas：尝试使用循环位图”。

以下代码段给出了调用recycle（）的示例。它使用引用计数（在变量mDisplayRefCount和mCacheRefCount中）来跟踪当前是在显示位图还是在缓存中。当满足这些条件时，代码会回收位图：


mDisplayRefCount和mCacheRefCount的引用计数均为0.

位图不为空，尚未回收。

对于API＆gt; = 11：

Android 3.0（API Level 11）引入了BitmapFactory.Options.inBitmap字段。如果设置了此选项，则采用Options对象的解码方法将在加载内容时尝试重用现有位图。这意味着重用了位图的内存，从而提高了性能，并删除了内存分配和取消分配。

加载新活动时获取OutofMemory异常？
