Error:Configuration with name 'default' not found - Libraries in Android Studio -

i added external library "floatingactionbutton-master" downloaded https://github.com/makovkastar/floatingactionbutton when sync gradle error: enter image description here

(i don't have enough reputation poste image) tried many differents answers forum nothing helpful case. don't know problem.

settings.gradle:

include ':app' include ':librerias:floatingactionbutton-master' 

app/build.gradle:

apply plugin: 'com.android.application'  android { compilesdkversion 22 buildtoolsversion "24.0.1"  defaultconfig {     applicationid "com.example.ezequiel.memories"     minsdkversion 22     targetsdkversion 22     versioncode 1     versionname "1.31.08" } buildtypes {     release {         minifyenabled false         proguardfiles getdefaultproguardfile('proguard-android.txt'), 'proguard-rules.pro'     } } }  dependencies { compile filetree(include: ['*.jar'], dir: 'libs') compile project(':librerias:floatingactionbutton-master') } 

to include library don't need clone/download repository nor add source manually, should add dependency follows:

dependencies {     ...     compile 'com.melnykov:floatingactionbutton:1.3.0' } 

however, according library, should not use anymore because deprecated android supporting library comes fab (floatingactionbutton) button.

to use button supporting library, should instead add following:

dependencies {     ...     compile 'com.android.support:design:24.2.0' } 

and use in layout:

<android.support.design.widget.floatingactionbutton         android:layout_width="wrap_content"         android:layout_height="wrap_content"         ... /> 

you can see following code lab more details.
