我为我的大学做了一个测试程序，它按照教程使用谷歌地图。我在教程中做了所有事情，但是我的应用程序在显示任何消息“不幸的是 SocialFoot 已停止”之前就崩溃了。我尝试调试，似乎它甚至在进入 onCreate 方法之前就崩溃了。这是我的代码：

package it.univpm.dii.socialfoot;

import com.actionbarsherlock.app.SherlockMapActivity;
import android.os.Bundle;

public class SocialFootActivity extends SherlockMapActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

    @Override
    protected boolean isRouteDisplayed() {
            // TODO Auto-generated method stub
            return false;
    }

}

日志表明应用程序正在尝试启动it.univpm.dii.socialfoot.activities.SocialFootActivity，但SocialFootActivity在包中it.univpm.dii.socialfoot。如果这发生在您的应用程序开始时（因为该活动被设置为启动活动），我会尝试清理和重建您的项目并重试。
