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);

当我将应用程序与最后一行一起使用时，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 sdcard 的根目录中。

它适用于 Eclipse 上的 android 应用程序。

这与读取位图文件无关。UnsatisfiedLinkError意味着它无法找到.so实现该类的共享对象（文件）。这意味着您的项目配置有问题。您是否将所需文件复制到libs/armeabi和？libs/armeabi-v7alibs/x86
