Could Not Find Constraint Layout Inside Android Studio

Everything was working fine inside studio, but then I get error: Could not find com.android.support.constraint:constraint-layout:1.0.0-beta4. Problem is that I can not install Con

Solution 1:

I am using Android 2.2

if you use preview 1 than try with

compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha1'

Gradle

classpath 'com.android.tools.build:gradle:2.2.0'

inside gradle wrapper

distributionUrl=https://services.gradle.org/distributions/gradle-2.14.1-all.zip

make sure you un-check from offline if you have not gradle 2.14.1

build Tools Version

buildToolsVersion ' 25 '

Best way if you have installed gradle 2.14.1-all then just go to your layout and then design tab, rignt click on your layout, click to convert,if you haven't installed Constraint lib you see a popup that says install lib, and click on ok. and then you can see in app level gradle file Constraint layout dependency added.
