ExternalNativeBuild {// use ndk-build ndkBuild {path 'src/main/jni/Android. mk '} // use the following configuration if cmake is used // cmake {// path 'src/main/jni/CMakeLists.txt '//}}

 

When these nodes are not added, I can compile and run the. so dynamic library. After these nodes are added, the above error occurs. First, I saw NDK_PROJECT_PATH = null. the so library is not well connected, so I have been google for a long time. There are probably the following solutions. You can try it one by one: 1. Modify sourceSets in gradle under module to specify the dynamic library path node, this node is used to configure the jni library path. In the Android Studio environment, the default jniLibs path is src/main/jniLibs. If you are porting from an old project, the directory may not exist. You can add the following configuration in the android node:

// Specify the dynamic library path sourceSets {main {jni. srcDirs = [] // disable automatic ndk-build call, which ignore our Android. mk jniLibs. srcDir 'src/main/libs '}}

 

2. There are also solutions to put the compiled dynamic library under the app/libs directory, because this directory stores the jar package by default, put the compiled dynamic library in the app/libs directory, and then add the following configuration to the android node:

sourceSets {        main {            jniLibs.srcDirs = ['libs‘]        }    }

 

3. If both of the above solutions do not solve your problem, it is likely that your Android. mk configuration problem. Does your Android. mk have a total Android. mk, and then include other Android. mk? If yes, you should reconfigure your sub-Android. mk. Like the OpenCV native library, it uses a general Android. mk and includes other sub-Android. mk. The OpenCV library is configuration-free and I have compiled it successfully. I got the first error because when I configured the levmar library, levmar used a third-party library (clapack), and the Sub-Android. mk was not configured. Finally, I went to the clapack library because the project did not use the clapack library. Finally, the compilation is successful. I have also said that my purpose is to debug C/C ++ code. After compilation is successful, the debug environment is actually configured, but the debug environment still cannot be used. That is to say, the Code in that line sets the breakpoint and runs there, but it still cannot be stopped. Debug detects the error only when the C/C ++ code reports an error. This problem has not been solved. It is very likely that I use a large number of third-party compiled dynamic libraries and directly use the source code, such as ffmpeg and opencv.
