compile \'com.google.android.gms:play-services:8.3.0\'
compile \'com.android.support:support-v4:22.2.1\'
compile \'com.android.support:design:22.2.1\'

Answer 1

Instead of:

compile 'com.google.android.gms:play-services:8.3.0'
compile 'com.android.support:support-v4:22.2.1'
compile 'com.android.support:design:22.2.1'

try:

playVersion = '8.3.0'
supportVersion = 'support-v4:22.2.1'
designVersion = '22.2.1'
compile "com.google.android.gms:play-services:$playVersion"
compile "com.android.support:$supportVersion"
compile "com.android.support:design:$designVersion"

Remember to replace the 's with "s.
