Android Studio got very slow and constantly "updating indices" : <p>There are more similar question on the SO, but I haven't found my answer on any of them so I am opening new one. </p>

<p>I am using: </p>

<p>Android Studio 2.2.3 (but was same with the 2.2.2)
Gradle 2.14.1 
JRE 1.8.0 </p>

<p>I am using it on the mac, OS X El Capitan (2.5 GHz, i5, 8GB RAM).</p>

<p>It has been working great until few weeks ago, and now it is so painfully slow. Most of the time it is <strong>"indexing/updating indices"</strong>. </p>

<p>I am not that concerned about build time (it takes about 30-40sec, but I can live with that) as much as that constant indexing that makes coding almost impossible (overall responsiveness is pretty poor).</p>

<p>Is there anything in my gradle files that could cause this? </p>

<p>I do have some dependencies, but the app itself is relatively simple. </p>

<p>build.gradle //app</p>

<p>build.gradle//project</p>

    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'

        classpath 'com.google.gms:google-services:1.5.0-beta2'

       }
    }

    allprojects {
        repositories {
            jcenter()
        }
    }

    task clean(type: Delete) {
            delete rootProject.buildDir
    }
</code></pre>

<p>P.S. 
I have enabled - offline work, parallel and daemon. I have increased VM heap size. I have uploaded to latest Android Studio. I have replaces maven with jcenter().
Is there anything I am missing?</p>
