I'm new in android. I tried to build a project from youtube tutorial but in this layout I got some errors and can't solve it. Someone said me problem in my support library But I don't understand what to do.
Here is my library:
compile 'com.android.support:design:26.+'
compile 'com.cepheuen.elegant-number-button:lib:1.0.2'
compile 'com.android.support:design:26.+'
compile 'com.android.support:appcompat-v7:26.+'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.google.firebase:firebase-core:10.2.0'
compile 'com.google.firebase:firebase-database:10.2.0'
compile 'info.hoang8f:fbutton:1.0.5'
compile 'com.rengwuxian.materialedittext:library:2.1.4'
compile 'com.android.support:cardview-v7:26.+'
compile 'com.android.support:recyclerview-v7:26.+'
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'com.firebaseui:firebase-ui-database:1.2.0'
testCompile 'junit:junit:4.12'
Here is the error log:
