Actionbar is now Toolbar... how to convert?

Hi Henrique, i was thinking the same thing! you could check out the Toolbar's doc and this post from the Android Developers Blog.

Goodluck! :-)

Hi Henriques, action bar ON and OFF can be supported by theme you will use: in Android studio please go to

res/values/styles.xml Example 1 (no action bar)

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
</style> 

Example 2 (with action bar)

 <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
 </style> 

To review all theme list please remove parent and simply you can start typing Theme.... or android etc. For some of the themes you will need to add dependencies to your gradle file (some are supported from the start) I noticed also that latest version of Android studio is adding it already

Gradle file:

in the latest version of Android Studio please go to:

GradleScripts/buildgradle(Module app)

and review section (below my file)

 dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.2'
}

In older version gradle file might be in different place (and if remember correctly it was just one gradle called buildgradle.

After you will change please find in top menu: Sync Project Gradle File - this button should on left from AVD Manager.

Thanks, Hubert
