我正在Qt和OpenCV中制作Android应用程序。
它正在使用桌面Linux,但在Android上失败了:
D/dalvikvm( 8059): Trying to load lib /data/app-lib/com.myselfxyz.testapp-1/libTestApp.so 0x421b4f98
E/dalvikvm( 8059): dlopen("/data/app-lib/com.myselfxyz.testapp-1/libTestApp.so") failed: Cannot load library: soinfo_link_image(linker.cpp:1673): could not load library "libopencv_java3.so" needed by "libTestApp"; caused by load_library(linker.cpp:771): library "libopencv_java3.so" not found
在我的设备上部署应用程序后,文件 libopencv_java3.so 位于 / data / app-lib / com中的 libTestApp.so 旁边。 myxyz.testapp-1 目录,所以我不知道,为什么不能找到它。
我正在使用:
我的qt pro文件如下:

答案 0 :(得分:0)
这个答案假设您已经设法在没有opencv的情况下运行您的应用程序,所以其余的都是相应的。
转到项目设置,找到“构建步骤”。
应该有一个名为构建Android APK 的步骤。点击详细信息。在其他库列表中,添加libopencv_java3.so
。它通常位于\sdk\native\libs\armeabi-v7a
文件夹中。
