带有NDK-Build的Android Studio - 不在Project Navigator中显示C ++文件

时间：2017-10-06 02:50:28

标签： android c++ android-studio android-ndk android-studio-2.3

我使用带有NDK-Build的Android Studio并且它没有显示单个C ++文件，因此我无法进行调试。它只显示了一个cpp-Folder和insid ethe文件夹，它显示了一些静态库，我无法进一步介绍。我记得曾经有可能进入这些库（它们像文件夹一样打开）并查看单个cpp文件。

这是我的build.gradle文件：

    import java.util.regex.Pattern
    import com.android.build.OutputFile
    import org.apache.tools.ant.taskdefs.condition.Os


    apply plugin: 'com.android.application'
    apply plugin: 'io.fabric'



    task('increaseVersionCode') << {
        def buildFile = file("build.gradle")
        def pattern = Pattern.compile("versionCode\\s+(\\d+)")
        def manifestText = buildFile.getText()
        def matcher = pattern.matcher(manifestText)
        matcher.find()
        def versionCode = Integer.parseInt(matcher.group(1))
        def manifestContent = matcher.replaceAll("versionCode " + ++versionCode + "")
        buildFile.write(manifestContent)
    }

    // DO NOT change the build.gradle on debug builds any longer, since this will lead to debugging not work and Android Studio / Gradle crash
    tasks.whenTaskAdded { task ->
        if (task.name == 'generateReleaseBuildConfig' /*|| task.name == 'generateDebugBuildConfig'*/) {
            task.dependsOn 'increaseVersionCode'
        }
    }



    task deleteGraphicsAssets(type: Delete) {
        println 'Grade: Deleting unnecessary assets...'
        delete "assets/1136p"
        delete "assets/2048p"
    }
    preBuild.dependsOn deleteGraphicsAssets

如果我删除以下位，cpp文件夹就不见了 - 所以它确实做了些什么......但是没有显示单个文件：

externalNativeBuild {
    ndkBuild {
        if (!project.hasProperty("PROP_NDK_MODE") || PROP_NDK_MODE.compareTo('none') != 0) {
            // skip the NDK Build step if PROP_NDK_MODE is none
            path "jni/Android.mk"
        }
    }
}

这里还有Android.mk：

我已经离开了一段时间，评论发生了什么：）

无论如何，根据这个文档，你应该在java文件夹下有cpp group文件夹。

当我在CMake项目中遇到此问题时，解决方案是我没有将.cpp文件正确添加到CMakeLists.txt

当我用这样的条目编辑CMakeLists 

add_library( # Sets the name of the library.
         myNative-lib
         # Sets the library as a shared library.
         SHARED
         # Provides a relative path to your source file(s).
         myCppFile.cpp )

然后我可以看到myCppFile.cpp。

在我的情况下，NDK在 Project Structure | SDK Location | Android NDK Location 即使NDK是随SDK Manager安装的。

单击组合框并选择NDK后，cpp文件夹开始填充我的本机源。

答案 3 :(得分：0)

您的Gradle构建工具使用什么版本？ 在将其更改为3.4.2之前，我一直使用较旧的版本，并且可以在项目层次结构中看到我的文件。 

buildscript {
repositories {
    google()
    jcenter()
}

dependencies {
    classpath 'com.android.tools.build:gradle:3.4.2'
   }
}

答案 4 :(得分：0)

首先下载NDK ...

转到文件-项目结构，然后单击SDK位置标签

enter image description here

然后使用完整项目将路径移动到C：//（不要尝试仅在项目内部导入模块）...

再次导入项目，但从C：//

如果没有成功尝试其他路径，请尝试，尝试，尝试

您必须尝试，因为问题是您必须找到CmaleLists.txt的正确路径...
（example＃设置双簧管库目录路径 设置（OBOE_DIR ../../../../ ..）......等）...但是有时路径不是您看到的路径...
