I want to use the appcompat for my project in AIDE. so I downloaded the jar file, add it into lib folder & coded my project. but when I theming, by putting the code
android:theme="@style/Theme.AppCompat"
into AndroidManifest.xml, it gets an error, showing that no resources found that matches the name. I modified the project.properties file, but still the same thing happens. what shall I do?
