我正在尝试从 Pardom 实现 ActiveAndroid 数据库包。我创建了一个简单的自定义类：

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();
    }

}

并将以下内容添加到清单中：

 <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>

但是应用程序崩溃了这个堆栈跟踪：

我不确定这里有什么问题。我在 java 构建路径中添加了 .jar 文件。然而我得到了这个 classnotfound 异常。该应用程序在我导入 android.app.Application 时加载。

好的，我得到了答案。复制您下载的 ActiveAndroid .jar并将其放入libs/文件夹中。

然后，在 Eclipse 中，打开libs文件夹，右键单击该.jar，并将其添加到您的构建路径中。
