android studio 降,Android Studio 2.0稳定,降低了应用启动速度

我正在使用运行良好的Android Studio 1.5(不是很快).今天我将其更新为2.0稳定版本,现在启动需要2-3分钟才能启动.第一次启动后,我立即查看了应用信息屏幕,发现第一个缓存中有41MB(因不同设备而异)缓存开始.我不知道发生了什么.这是我的gradle文件

apply plugin: 'com.android.application'

android {

compileSdkVersion 23

buildToolsVersion "23.0.2"

packagingOptions {

exclude 'META-INF/NOTICE'

exclude 'META-INF/LICENSE'

exclude 'META-INF/DEPENDENCIES'

exclude 'META-INF/DEPENDENCIES.txt'

exclude 'META-INF/LICENSE.txt'

exclude 'META-INF/NOTICE.txt'

}

sourceSets {

main.jniLibs.srcDirs = ['libs']

}

defaultConfig {

applicationId "com.my.app"

minSdkVersion 17

targetSdkVersion 21

multiDexEnabled true

}

buildTypes {

release {

minifyEnabled false;

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

}

}

dexOptions {

preDexLibraries = false

javaMaxHeapSize "2g"

}

}

dependencies {

compile fileTree(dir: 'libs', include: ['*.jar'])

compile project(':volley')

compile project(':android-country-picker-master')

compile project(':viewPagerIndicator')

compile ('com.android.support:design:23.1.1') {

}

}

}

compile ('org.apache.commons:commons-lang3:3.4'){

}

}

任何帮助,将不胜感激,谢谢

解决方法:

When using Instant Run with a project configured for Legacy Multidex—that is, when build.gradle is configured withmultiDexEnabled true and minSdkVersion 20 or lower—build performance may decrease when deploying a clean build to target devices running Android 5.0 (API level 21) or higher.

[..] To improve clean build performance during development, consider

creating a product flavor withminSdkVersion 21.

尝试在gradle中实现

android {

productFlavors {

// Define separate dev and prod product flavors.

dev {

// dev utilizes minSDKVersion = 21 to allow the Android gradle plugin

// to pre-dex each module and produce an APK that can be tested on

// Android Lollipop without time consuming dex merging processes.

minSdkVersion 21

}

prod {

// The actual minSdkVersion for the application.

minSdkVersion 14

}

}

...

buildTypes {

release {

runProguard true

proguardFiles getDefaultProguardFile('proguard-android.txt'),

'proguard-rules.pro'

}

}

}

dependencies {

compile 'com.android.support:multidex:1.0.0'

}
