Question

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Manifest：

 <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。当我导入android.app.Application时，应用程序会加载。

Answer 1

好的我得到了答案。复制已下载的ActiveAndroid .jar ，并将其放入 libs / 文件夹。

然后，在Eclipse中，打开 libs 文件夹，右键单击 .jar ，然后将其添加到构建路径中。
