Question

Sorry maybe this is not new topic, but really need help, i was try many post about this, but my problem still not fix, i am newbie about android. I try to learn Material Design,

Answer 1

To use the AppCompat Theme you have to include this library in your project.

 compile 'com.android.support:appcompat-v7:22.2.0'

Also I suggest you using the latest version 22.2.0 instead of 22.0.0

dependencies { 
     compile fileTree(dir: 'libs', include: ['*.jar'])
     compile 'com.android.support:appcompat-v7:22.2.0'

     //You can remove this line, because the appcompat has the support-v4 as dependency
     //com.android.support:support-v4:22.0.0'
    } 

Answer 2

In Android Studio Right click on Gradle and right click of mouse button Refresh Gradle project issues is resolved .

Answer 3

Theme Theme.AppCompat.* is used to define compatibility with old android 2.x versions. this requires the support-v7

If you need compatibility with android 2.2 or 2.3 include this in your gradle build

 compile 'com.android.support:support-v7:22.0.0'

or if you build is for android-3.0 or later replace AppCompat with Holo.

Example

• Theme.AppCompat.Light.NoActionBar

becomes

• Theme.Holo.Light.NoActionBar
