Actually the thing is that whenever I am going to execute my project from android studio its taking too much time means like 30 to 40 minute maybe more and sometime its immediately launch only when I sync my gradel with very minor changes. currently I have been using android studio 2.1 and I didn't do major changes in gradle despite this,android studio taking too much time to execute project. following is my gradle contains.
dependencies {compile fileTree(include: ['*.jar'], dir: 'libs')
//This line is added
