Il punto è che devi dire DOVE incontri il problema.
Una guida all'implementazione della libreria c'e' ed è proprio quella da te linkata (ed è una delle migliori wiki che abbia visto tra le varie librerie android)
Non penso abbia senso creare una guida per ogni libreria

Qui ce n'e' una ad esempio : https://github.com/thecodepath/andro...eAndroid-Guide

va bene così modificato AndroidManifest?
<?xml version="1.0" encoding="utf-8"?><br /> <manifest xmlns:android="http://schemas.android.com/<span class="forTooltip">apk</span>/res/android"<br /> package="com.activeandroid.xxx.xxxx"<br /> android:versionCode="1"<br /> android:versionName="1.0" ><br /> <br /> <uses-sdk<br /> android:minSdkVersion="14"<br /> android:targetSdkVersion="21" /><br /> <br /> <application<br /> android:allowBackup="true"<br /> android:icon="@drawable/ic_<span class="forTooltip">launcher</span>"<br /> android:label="@string/app_name"<br /> android:theme="@style/AppTheme" ><br /> <meta-data <br /> android:name= "AA_DB_NAME" <br /> android:value= "gestione.db" /> <br /> <meta-data <br /> android:name= "AA_DB_VERSION" <br /> android:value= "1" /><br /> <activity<br /> android:name=".MainActivity"<br /> android:label="@string/app_name" <br /> ><br /> <br /> <intent-filter><br /> <action android:name="android.intent.action.MAIN" /><br /> <category android:name="android.intent.category.LAUNCHER" /><br /> </intent-filter><br /> </activity><br /> </application><br /> <br /> </manifest><br />

Dopo questo passaggio ho creato una classe chiamata db e ci ho inserito questo codice preso dal link
