集成问题到tess-two（Tesseract Tools for Android）库到Android工作室并构建ndk

Question

我想在android studio中导入tess-two库，编译后在ndk build中显示错误。我已经尝试在stackoverflow上给出解决方案。 喜欢 ，  Execution failed for task ':app:compileDebugNdk' 但它没有解决我的问题。请建议我在哪里做错了。

它显示以下错误：

Error:error: undefined reference to 'isnanf'

事实证明，此错误的根本原因是NDK r11不支持android-8（Android 2.2.x），而NDK r10则支持。

将Application.mk文件更改为使用APP_PLATFORM := android-9可以解决此问题。
