JNI文件夹上的C / C ++文件夹中填写错误 [英] C/C++ file on JNI folder filled with errors

问题描述

背景

过去，我做了一个不错的Android库（链接和 来配置你的应用程序。

在项目结构（在Mac OS中的cmd +;）设置 Gradle版本到 1 code>和Android Plugin Version 留空

然后为您配置 app.gradle 文件

  android.ndk 
 {
 
 moduleName =MY_MODULE_NAME
 
 //这是您的附加包含文件
 //如果您在JNI文件夹内有子文件夹
 cppFlags + =-I $ {file（src / main / jni / myFolder / Sources）}。toString（）
 cppFlags + =-I $ {file（src / main / jni / myFolder / Sources / Helper）}toString（）
 cppFlags + =-I $ {file（src / main / jni / myFolder / Sources / Image）}。toString（）
 cppFlags + =-I $ {file（src / main / jni / myFolder / Sources / Utils）}。toString（）
 
 //添加c ++ 11支持
 cppFlags + =-std = c ++ 11
 
 //你的libs 
 ldLibs + = [log，jnigraphics] 
 
 stl =gnustl_static
} 
  

如果要使用例如 cpufeatures ，您必须添加它到你的JNI文件夹。然后在 app.gradle 文件中以这种方式指定路径。

  cppFlags + = - 我$ {file（src / main / jni / cpufeatures）}。toString（）
  

我的 app.gradle 文件

 应用插件：'com.android.model.application'
 model {
 android {
 compileSdkVersion = 21 
 buildToolsVersion =22.0.1
 
 defaultConfig.with {
 applicationId =com.example .testapp
 minSdkVersion.apiLevel = 17 
 targetSdkVersion.apiLevel = 22 
} 
 
} 
 android.ndk {
 moduleName = MY_MODULE_NAME
 
 //这是您的附加包含文件
 //如果您在JNI文件夹内有子文件夹
 cppFlags + =-I $ {file（ src / main / jni / myFolder / Sources）}。toString（）
 cppFlags + =-I $ {file（src / main / jni / myFolder / Sources / Helper）}toStr ing（）
 cppFlags + =-I $ {file（src / main / jni / myFolder / Sources / Image）}toString（）
 cppFlags + =-I $ {file （src / main / jni / myFolder / Sources / Utils）}。toString（）
 
 //添加c ++ 11支持
 cppFlags + =-std = c ++ 11 
 
 //你的libs 
 ldLibs + = [log，jnigraphics] 
 
 stl =gnustl_static
} 
 // jni是默认目录;如果你的目录是不同的目录，你可以配置这个
 android.sources {
 main {
 jni {
 source {
 srcDirs'src / main / jni'
 } 
} 
} 
} 
 android.buildTypes {
 release {
 isMinifyEnabled = false 
 proguardFiles + = file（'proguard-rules .txt'）
} 
} 
 android.productFlavors {
 create（arm7）{
 ndk.abiFilters + =armeabi-v7a
} 
 create（arm8）{
 ndk.abiFilters + =arm64-v8a
} 
 create（x86-32）{
 ndk .abiFilters + =x86
} 
 //详细的abiFilter描述，请参阅支持的ABI@ 
 // https://developer.android.com/ndk/guides/ abis.html＃sa 
 //构建一个包括所有productFlavors 
 create（fat）
 
}

Background

In the past, I've made a nice Android library (link here) that allows the developers to contain a bitmap within C/C++ world, play with it, and later convert it back to Java's world.

The problem

Now that I try to import it, I fail to do so on both Eclipse and Android-Studio.

For Android-Studio, I can understand, since it doesn't really support it well yet, but for Eclipse, I've done it many times and it worked fine. I've even made a tutorial based on the problems I've collected over time.

No matter what I do, this is what I get:

A lot of errors in the form of "Type 'X' could not be resolved" .

This also leads to failure in creating the files the sample needs in order to run.

On Android Studio, I get this error:

System Info

Windows 8.1 64bit, Eclipse 4.4.1, ADT 23.0.4.1468518, NDK r10d 64bit

The question

How do I fix it?

What is wrong with my library?

Also, what should I do in order to allow Android Studio users import it?

解决方案

As you know Google announced the new update of Android studio 1.3 RC3, and finally we get C++ support. I configure my app this way and everything working just fine.

Fallow this steps...

1. Run Android Studio 1.3 RC3 and click Import Project (Eclipse ADT, Gradle, etc.)
2. See this and this to configure your app.

3. In project structure (cmd + ; in Mac OS) set Gradle version to 1 and Android Plugin Version leave blank

4. Then configure you app.gradle file

    android.ndk 
    {
   
       moduleName = "MY_MODULE_NAME" 
   
       // this is your additional include files, 
       // do this if you have subfolder inside of JNI folder
       cppFlags += "-I${file("src/main/jni/myFolder/Sources")}".toString()
       cppFlags += "-I${file("src/main/jni/myFolder/Sources/Helper")}".toString()
       cppFlags += "-I${file("src/main/jni/myFolder/Sources/Image")}".toString()
       cppFlags += "-I${file("src/main/jni/myFolder/Sources/Utils")}".toString()
   
       // add c++ 11 support
       cppFlags += "-std=c++11"
   
       // your libs
       ldLibs += ["log", "jnigraphics"]
   
       stl     = "gnustl_static"
   }
   

if you want to use for example cpufeatures , you must add it to your JNI folder. Then in app.gradle file specify path to it in this way .

cppFlags += "-I${file("src/main/jni/cpufeatures")}".toString()

My app.gradle file

apply plugin: 'com.android.model.application'
model {
    android {
        compileSdkVersion = 21
        buildToolsVersion = "22.0.1"

        defaultConfig.with {
            applicationId = "com.example.testapp"
            minSdkVersion.apiLevel = 17
            targetSdkVersion.apiLevel = 22
        }

    }
    android.ndk {
        moduleName = "MY_MODULE_NAME" 

        // this is your additional include files, 
        // do this if you have subfolder inside of JNI folder
        cppFlags += "-I${file("src/main/jni/myFolder/Sources")}".toString()
        cppFlags += "-I${file("src/main/jni/myFolder/Sources/Helper")}".toString()
        cppFlags += "-I${file("src/main/jni/myFolder/Sources/Image")}".toString()
        cppFlags += "-I${file("src/main/jni/myFolder/Sources/Utils")}".toString()

        // add c++ 11 support
        cppFlags += "-std=c++11"

        // your libs
        ldLibs += ["log", "jnigraphics"]

        stl     = "gnustl_static"
    }
    // jni is the default dir; config this if yours is in different directory
    android.sources {
        main {
            jni {
                source {
                    srcDirs 'src/main/jni'
                }
            }
        }
    }
    android.buildTypes {
        release {
            isMinifyEnabled = false
            proguardFiles += file('proguard-rules.txt')
        }
    }
    android.productFlavors {
        create ("arm7") {
            ndk.abiFilters += "armeabi-v7a"
        }
        create ("arm8") {
            ndk.abiFilters += "arm64-v8a"
        }
        create ("x86-32") {
            ndk.abiFilters += "x86"
        }
        // for detailed abiFilter descriptions, refer to "Supported ABIs" @
        // https://developer.android.com/ndk/guides/abis.html#sa
        // build one including all productFlavors
        create("fat")
    }
}

My project gradle file

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle-experimental:0.1.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

My gradle-wrapper.properties file

#Mon Jul 20 16:12:41 AMT 2015
