Android Studio新项目文件大小太大 [英] Android Studio new project file size too big

问题描述

我刚刚在Android Studio 2.2.3中创建了一个新的android项目，仅带有一个空的Activity，但它仍然在设备上使用4.11 MB，考虑到它确实包含一个空的Activity，我认为这是很多的.为什么要占用这么多空间?有可能减小其尺寸吗?我下载的应用程序具有更多功能，并且具有更多图片，颜色等，并且小于2MB.

I just created a new android project in Android Studio 2.2.3 with just an empty Activity and still it uses 4.11 MB on the device which I think is a lot given that it does contain a single empty Activity. Why is it taking so much space? Is it possible to reduce its size? I have downloaded applications with more functionality and which have more pictures, colors, etc. and are less than 2MB.

下面是我创建项目所使用的步骤.

Bellow are the steps I used to create the project.

然后，在Sony Xperia上运行该应用程序后，我会获得此信息.

Then, after running the application on a Sony Xperia I get this information.

分析内存时，我得到了.

And when profiling the memory I get.

已分配了3MB和1MB的免费空间.

Which has allocated 3MB and ust 1MB free.

这是build.gradle文件:

This is the build.gradle file:

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "com.survey.research.surveycollect"
        minSdkVersion 17
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.1.1'
    compile 'com.android.support:design:25.1.1'
    testCompile 'junit:junit:4.12'
}

推荐答案

调试apk或发布apk?如果调试apk，则总是比发行版稍大.在释放模式下，执行minifyEnabled = true，shrinkResources = true，zipAlignEnabled = true.它将使发布文件的大小缩小到调试文件的30％(基于我的经验).

Debug apk or release apk? If debug apk its always slightly bigger than release. In release mode, do minifyEnabled = true, shrinkResources = true, zipAlignEnabled = true. It will shrunk your release file size to around 30% (base on my exp) of your debug files.
