試圖安裝ActiveAndroid，但得到ClassNotFoundException

Question

我試圖從Pardom實現ActiveAndroid數據庫包。我創建了一個簡單的自定義類：

package com.xxx.xxxx; 

import com.activeandroid.ActiveAndroid; 

public class CardiologyApplication extends com.activeandroid.app.Application { 
    @Override 
    public void onCreate() { 
     super.onCreate(); 
     ActiveAndroid.initialize(this); 
    } 

    @Override 
    public void onTerminate() { 
     super.onTerminate(); 
     ActiveAndroid.dispose(); 
    } 

} 

，並添加以下的清單：

<application 
     android:name="com.xxx.xxxx.CardiologyApplication" 
     android:allowBackup="true" 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" 
     android:theme="@style/Theme.MyTheme" > 
     <meta-data 
      android:name="AA_DB_NAME" 
      android:value="Cardiology2.db" /> 
     <meta-data 
      android:name="AA_DB_VERSION" 
      android:value="1" /> 

     <activity 
      android:name="com.xxx.xxxx.HomeActivity" 
      android:label="@string/app_name" 
      android:screenOrientation="portrait" 
      android:windowSoftInputMode="stateHidden|adjustResize" > 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 

       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 

    </application> 

但隨着該堆棧跟蹤應用程序崩潰：

我不知道這裏有什麼問題。我已經在java構建路徑中添加了.jar文件。然而我得到這個classnotfound異常。當我導入android.app.Application時，該應用程序會加載。

Answer 1

好的我得到了答案。複製已下載的ActiveAndroid .jar，並將其放入庫/文件夾中。

然後，在Eclipse中，打開庫文件夾，右擊該的.jar，並將其添加到您的構建路徑。
