[nitneuq33000]

hello, i tried to change the appbar color with modification of the styles.xml like this :

<style name="LaunchTheme" parent="@android:style/Theme.Black.NoTitleBar"> @drawable/launch_background </style>

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">#3f51b5</item>
    <item name="colorPrimaryDark">#3f51b5</item>
    <item name="colorAccent">#3f51b5</item>
</style>

but no change currently, always black appbar
