Please try to resolve the problem.

Answer 1

android:Theme.Material requires API level 21 and so it's cleared that your minSDKVersion is lower than 21.

If you really want to develop app for API 21 then declare android:minSDKVersion=21.

And if in case you want to provide compatibility to lower version then you need to use support library, which is commonly known as AppCompat library.

You can access above attributes using AppCompat:

 <item name=”colorPrimary”>@color/primary</item>
 <item name=”colorPrimaryDark”>@color/primary_dark</item>

Answer 2

Actually, you can use this attribute, using the support library:

<style name="AppTheme" parent="@style/Theme.AppCompat.Light">

    <item name="colorPrimary">...</item>
</style>

You can also use the others:

    <item name="colorPrimaryDark">...</item>
    <item name="colorAccent">...</item>
