使用Android Studio構建的應用程序Apk大於使用Eclipse構建的應用程序Apk

Question

最近，我將項目遷移到Android Studio 。 該項目引用一個庫項目而不復制它（請參閱此答案 ）。

我注意到，Android Studio生成的apk大於Eclipse生成的apk（ 幾乎是Eclipse的兩倍 ）。 當我解壓縮這兩個apk文件時，我發現Android Studio中的apk中還有一個文件夾“ main”，其中包含“ res”文件夾和AndroidManifest.xml。

問題是apk的主目錄中存在“ res”文件夾（/ res），其中包含相同的資源（/ main / res）。

我認為下一個gradle文件會導致問題，但是沒有它，就無法構建項目。

的build.gradle我的庫模塊- my_android_project_lib模塊

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'
    }
}
allprojects {
    repositories {
        jcenter()
    }
}

apply plugin: 'com.android.library'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 21
    }

    // I think this duplicates the resources
    sourceSets {
        main {
            manifest.srcFile 'my_android_project_lib/src/main/AndroidManifest.xml'
            java.srcDirs = ['my_android_project_lib/src']
            resources.srcDirs = ['my_android_project_lib/src']
            aidl.srcDirs = ['my_android_project_lib/src']
            renderscript.srcDirs = ['my_android_project_lib/src']
            res.srcDirs = ['my_android_project_lib/src/main/res', 'slidingMenuLib/src/main/res']
            assets.srcDirs = ['my_android_project_lib/src/main/assets']
        }
    }
}

dependencies {
    compile project(':slidingMenuLib')
    compile fileTree(dir: 'my_android_project_lib/libs', include: ['*.jar'])
    compile fileTree(dir: 'slidingMenuLib/libs', include: ['*.jar'])
    compile 'com.google.code.gson:gson:1.7.1'
}

settings.gradle

include ':my_android_app'
include ':my_android_project_lib'
include ':slidingMenuLib'
project(':my_android_project_lib').projectDir = new File(settingsDir, '../my_android_project_lib')

為的build.gradle模塊my_android_app

apply plugin: 'com.android.application'

android {
    compileSdkVersion 19
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "my.android.app"
        minSdkVersion 15
        targetSdkVersion 19
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile project(path: ':my_android_project_lib')
}

為的build.gradle項目my_android_app

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

您知道如何解決該問題嗎？ 我缺少重要的東西。

Answer 1

我發現了問題。 當我從my_android_project_lib模塊的build.gradle中刪除以下行時，應用程序的大小恢復為正常。

resources.srcDirs = ['anyoption_android_v2_lib/src']

my_android_project_lib模塊的最終build.gradle是：

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'
    }
}
allprojects {
    repositories {
        jcenter()
    }
}

apply plugin: 'com.android.library'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 21
    }

    // The problem is here.
    sourceSets {
        main {
            manifest.srcFile 'my_android_project_lib/src/main/AndroidManifest.xml'
            java.srcDirs = ['my_android_project_lib/src']
            res.srcDirs = ['my_android_project_lib/src/main/res']

            // Removed
            // resources.srcDirs = ['my_android_project_lib/src'] - MAIN PROBLEM
            // aidl.srcDirs = ['my_android_project_lib/src']
            // renderscript.srcDirs = ['my_android_project_lib/src']
            // res.srcDirs = ['my_android_project_lib/src/main/res', 'slidingMenuLib/src/main/res']
            // assets.srcDirs = ['my_android_project_lib/src/main/assets']
        }
    }
}

dependencies {
    compile project(':slidingMenuLib')
    compile fileTree(dir: 'my_android_project_lib/libs', include: ['*.jar'])
    compile fileTree(dir: 'slidingMenuLib/libs', include: ['*.jar'])
    compile 'com.google.code.gson:gson:1.7.1'
}

在評論

resources.srcDirs = ['src']

在build.gradle文件中，對我build.gradle 。

build.gradle文件中的build.gradle看起來像這樣，

sourceSets {
    main {
        manifest.srcFile 'AndroidManifest.xml'
        java.srcDirs = ['src']
      //  resources.srcDirs = ['src']
        aidl.srcDirs = ['src']
        renderscript.srcDirs = ['src']
        res.srcDirs = ['res']
        assets.srcDirs = ['assets']
    }

    // Move the tests to tests/java, tests/res, etc...
    instrumentTest.setRoot('tests')

    // Move the build types to build-types/<type>
    // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
    // This moves them out of them default location under src/<type>/... which would
    // conflict with src/ being used by the main source set.
    // Adding new build types or product flavors should be accompanied
    // by a similar customization.
    debug.setRoot('build-types/debug')
    release.setRoot('build-types/release')
}
