Android - 兼容性库v4异常(EdgeEffect)java.lang.NoClassDefFoundError:> android.widget.EdgeEffect

Question

如果有帮助的话,我也在使用SherlockActionBar.

触发此异常的行是: setContentView(R.layout.activity);

我正在上课 extends SherlockFragmentActivity

应用程序名称为com.testapp.androidapp

该类是:com.testapp.androidapp.SwipeyTabsActivity.

我在几款手机上试过这个应用程序,除了这台设备之外,Nexus S.除了这个设备之外,所有设备都报告了Android的实际版本号(4.0.1,2.3.3),这是唯一的设备有一个命名版本(IceCreamSandwich).

问题是,我如何确保不会发生此错误？如果有帮助,我不需要效果(EdgeEffect).

这些是我的进口:

import com.actionbarsherlock.app.ActionBar;
import com.actionbarsherlock.app.SherlockFragmentActivity;


import android.content.Context;
import android.content.Intent;
import android.os.Bundle;

Answer 1

如果在异常发生之前向上滚动LogCat,你会看到一条类似的行Unable to find the superclass for that class.

您将遇到此错误的原因只有三个:

1. 这堂课真的不存在.如果您使用的是官方示例中的代码并获得此代码,请确保您拥有该库的最新版本
2. 您尚未将jar添加到构建路径中.要解决此问题,请右键单击Eclipse中的jar,然后执行BuildPath►Addto Build Path.
3. 你的jar不在/ libs文件夹中.将jar添加到构建路径时会发生这种情况,但较新版本的ADT需要将它放在/ libs中.把它放在那里并重新添加到构建路径.
