这是我正在尝试使用的代码
File filePath = new File(Environment.getExternalStorageDirectory(), "/test.bmp");
String file = filePath.getAbsolutePath();
Mat input_mat = Highgui.imread(file);
当我使用最后一行的应用程序时,它会崩溃。我不确定最后一行是错误还是我没有正确访问test.bmp文件。它保存在SD卡的根目录中。
这是针对eclipse上的Android应用程序。

答案 0 :(得分:3)
这与读取位图文件无关。 UnsatisfiedLinkError
表示无法找到实现该类的共享对象(.so
文件)。这意味着您的项目配置出了问题。您是否已将所需文件复制到libs/armeabi
,libs/armeabi-v7a
和libs/x86
?
