我是Android的初学者。我想要一个使用这个库的示例应用程序：https ://github.com/puelocesar/android-lib-magick 。我之前尝试使用https://github.com/lilac/Android-ImageMagick - 我做了很多更改以使其工作，但我得到的结果并不令人满意。
我只是想知道哪个类需要特定的东西。
这些是我使用https://github.com/lilac/Android-ImageMagick得到的效果
模糊，木炭和无效果看起来完全一样。当我选择边缘时，它显示模糊图像。并且出现了噪点效果，但它们看起来像是在该图像上手动绘制了红点和绿点。
下面是运行应用程序的代码。
它使用硬编码名称和扩展名搜索 sd 卡中的图像。它得到了所有的 ibages，但我无法理解它对这些图像做了什么，因为它在屏幕上只显示一个图像。
也不知道 test.txt 是创建的。此代码作为 AndroidMagickActivity 存在于库中
经过长时间的搜索，我对 android.mk 文件进行了一些更改，现在它正在运行，但输出不是那么好。
请任何人帮助我改善丁香库的结果或帮助我了解如何使用https://github.com/puelocesar/android-lib-magick
我是初学者，我不知道如何使用 NDK 以及如何创建 JNI 和 .so 文件
