在manifest 中不能粗心的这样写啊

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme"
        android:name=".MainActivity">

需要再建一个application类 extends GDApplication

override  various methods in order to style your application

public class MyApplication extends GDApplication{
     @Override
        public Class<?> getHomeActivityClass() {
            return MainActivity.class;
        }
        
        @Override
        public Intent getMainApplicationIntent() {
            return new Intent(Intent.ACTION_VIEW, Uri.parse(getString(R.string.app_url)));
        }

}

 android:name=".MyApplication">

You finally need to make your project use the GreenDroid base theme. In your AndroidManifest.xml, go to the application tag and add android:theme="@style/Theme.GreenDroid" as a new attribute.
