Answer 1

All that errors “color error or font error” came from higher version of firebase ui in graddle/app. Try to use lower version of it.

Or try to use this:

          maven {
               url 'https://maven.google.com'
                      }

And you can always check: https://firebase.google.com/support/release-notes/android

And try to add this:

  android {
             compileSdkVersion 26
             buildToolsVersion "26.1.0"
    defaultConfig {
      applicationId "..."
            minSdkVersion 22
            targetSdkVersion 26

Or decrease sdk and AppCompat version to check if the lower version works fine.

         compileSdkVersion 25
             buildToolsVersion "25.3.1"
         defaultConfig {
      applicationId "..."
            minSdkVersion 22
            targetSdkVersion 25

....

   'com.android.support:cardview-v7:25.3.1'
    compile 'com.android.support:design:25.3.1'

And so on.

In addition don't forget to reboot your Mac at least once in a week) emulator works better
