当我从FullScreenImageActivity导航到EditProfileFragment类时，我收到以下错误：

但是当我重新打开我的应用程序时，它会设置图像。第一次设置图像时如何避免OOM？请尽快帮我解决代码。

可能是错误发生，因为我正在尝试设置在FullScreenImageActivity.java类中打开的MainActionBarActivity.java中的图像。我认为当FullScreenImageActivity.java类关闭时，VM堆不会被回收，或者在MainActionbarActivity.java类中加载图像时应用程序崩溃。

这是我的MainActionBarActivity.java类的代码：
