Android Studio 2.0稳定,降低了应用启动速度

概述我正在使用运行良好的AndroidStudio1.5(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applyplugin:'com.android.appl

任何帮助,将不胜感激,谢谢

解决方法:

如此处所述：http://tools.android.com/tech-docs/instant-run

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'}
