Android - 输出类com.hultan.formler.ResizableImageView时的OutOfMemoryError

Question

我最近修改了我的应用。我添加了大约30个不同的片段（但同时使用的片段不超过2个）。我不知道这是否会耗尽内存并导致问题。无论如何，只要我打开这个片段，应用程序就会崩溃。我用log来找出问题所在。但我不知道 问题是什么。

令人讨厌的部分是，在我添加30个几乎相同的fragments（这是导航到这个特定片段的导航）之前，这个确切的代码工作得很好。

@GopalRao解决了这个问题！我的照片显然太大了。我将它们的大小调整到大约40％的大小，现在它的工作完好无损！
