解决方案

18的图像它不是一个大数目。如果你有OutOfMemoryError异常，这意味着您的图片只是大。最简单，最好的办法是调整（降低）这些图像的分辨率，你真正需要的大小。

如果您需要与喜清晰度的图像，那么你应该在使用的情况下，如果缩影他们在小规模显示出一些奇怪的原因，因此在一次只有一个或两个图像在全分辨率psented $ P $。
为了使这取决于细节水平绘制项目交替使用的ImageView .setImageLevel （改变的细节水平），并定义资源作为 LevelListDrawable 。

调用的完成的里面的的onPause 的是非常糟糕的主意！

I have 18 images which create a flower when overlap eachother as a stack in my and app. All images are added to activity in XML file android:src:'@drawable/blabla..'...

解决方案

18 images it is not a big number. If you have OutOfMemoryError this means that your images are simply to big. Simplest and best approach is to adjust (reduce) resolution of those images to the size you really need.

If for some strange reason you need images with hi resolution then you should use miniatures in case if they are shown in small scale, so only one or two images at once are presented in full resolution. To make alternations of drawable item depending of level of details use ImageView.setImageLevel (to change level of details) and define resource as LevelListDrawable.

Calling finish inside onPause is very bad idea!
