gradle - Android Studio build too slow multidex application -

when add project multidex:true, , make application class extends multidexapplication, project build time passed 20 sec around 90 sec.how faster?

if me tried vic vu's solution still can't avoid enabling multidex can try (as long using device has android 5.0 , above).

note speed development build. production build still slow.

basically need introduce 2 product flavors 1 dev , 1 prod.

add multidexenabled true

android {     productflavors {         // define separate dev , prod product flavors.         dev {             // dev utilizes minsdkversion = 21 allow android gradle plugin             // pre-dex each module , produce apk can tested on             // android lollipop without time consuming dex merging processes.             minsdkversion 21         }         prod {             // actual minsdkversion application.             minsdkversion 14         }     }           ...     buildtypes {         release {             runproguard true             proguardfiles getdefaultproguardfile('proguard-android.txt'),                                                  'proguard-rules.pro'         }         defaultconfig {             applicationid "com.something.something"             targetsdkversion 23             versioncode 1             versionname "1.0.0"              multidexenabled true         }     } dependencies {   compile 'com.android.support:multidex:1.0.1' } 

and have class extends application had override attachbasecontext()

@override protected void attachbasecontext(context base) {     super.attachbasecontext(base);     multidex.install(this); } 

if not extending application use multidexapplication in androidmanifest.xml application tag.

ensure in android studio build variants pointing devdebug.
