Android Studio编译开源项目（含NDK开发）常见报错

Posted 2020-09-22 _yegong

1.未设置NDK的路径

Error:Execution failed for task \':library:ndkBuild\'. > A problem occurred starting process \'command \'null/ndk-build\'\'
配置NDK的的安装路径即可。
1）设置环境变量：新增android_NDK_HOME键值为Android NDK安装目录，在PATH末尾增加;%ANDROID_NDK_HOME%。

或者2）在AS的project structure设置，如下图：

 

2. 调用的ndk-build命令不对

Error:Execution failed for task \':library:ndkBuild\'.> A problem occurred starting process \'command \'D:\\androidDev\\android-ndk-r10e/ndk-build\'\'

在stackoverflow上找到原因，build.gradle文件中

taskndkBuild(type: Exec,description:\'Compile JNI source via NDK\') {
    defndkDir =project.plugins.findPlugin(\'com.android.library\').sdkHandler.ndkFolder
    workingDir"$projectDir/src/main/jni"
    commandLine"$ndkDir/ndk-build"
}

　　

commandLine"$ndkDir/ndk-build"这一行windows下应该用ndk-build.cmd（项目中有遇到）

3. 找不到boost库文件

项目Readme中有说明

Manual Build
Make sure$ANDROID_NDK_HOMEis correctly set to the root directory of your NDK installation. Also, if Boost lives in a non-standard directory (or you\'re on Windows) you\'ll need to set$BYPASS_INCLUDE_PATH to its parent directory.

　　

设置环境变量：新增BYPASS_INCLUDE_PATH键值为boost的安装目录，在PATH末尾增加;%BYPASS_INCLUDE_PATH%。
