Android Studio編譯開源項目（含NDK開發）常見報錯

1.未設置NDK的路徑

Error:Execution failed for task ':library:ndkBuild'. > A problem occurred starting process 'command 'null/ndk-build''
配置NDK的的安裝路徑即可。
1）設置環境變量：新增ANDROID_NDK_HOME鍵值為Android NDK安裝目錄，在PATH末尾增加;%ANDROID_NDK_HOME%。

或者2）在AS的project structure設置，如下圖：

 

2. 調用的ndk-build命令不對

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"這一行windows下應該用ndk-build.cmd（項目中有遇到）

3. 找不到boost庫文件

項目Readme中有說明

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.

　　

設置環境變量：新增BYPASS_INCLUDE_PATH鍵值為boost的安裝目錄，在PATH末尾增加;%BYPASS_INCLUDE_PATH%。
