android demo编译报错

[qipengwang]

gradle sync的时候会提示： ERROR: Cause: executing external native build for cmake D:\Project\chineseocr_lite-master\android_demo\app\src\main\cpp\CMakeLists.txt

我在win10下配置，环境和readme里面一致，cmake我的版本不对，针对这个项目重新下了个，然后在local.properties里面配置了 cmake.dir=C\:\Users\wqp\AppData\Local\Android\Sdk\cmake\3.10.2.4988404

你可以把完整的错误发出来 我在调试的时候发现，如果CMakeLists.txt 中添加编译的库你在其他地方没有使用，sync也会报错的，所以，我建议你一步一步的调试

在build gradle 中 去掉 '-static-openmp' 再试试

这是包名错误导致的问题，已经提交了修复了 修改mytext_jni.cpp 里面的文件 jni 函数名为 Java_com_ncnn_demo_textocr_Detect Java_com_ncnn_demo_textocr_Init

检查一下jni.cpp文件中函数的包名是不是正确的，如果不正确会显示红色的标记
