Question

我是Android新手，我正在根据地图构建应用。当我尝试启动我的应用程序时，出现错误，“应用程序AdBaiduMapDemo02意外停止。请再试一次。” 以下是LogCat的说法：

我的MainActivity代码如下：

package com.example.adbaidumapdemo02;  
import com.baidu.mapapi.BMapManager;  
import com.baidu.mapapi.GeoPoint;  
import com.baidu.mapapi.MapActivity;  
import com.baidu.mapapi.MapController;  
import com.baidu.mapapi.MapView;  
import android.os.Bundle;  
public class MainActivity extends MapActivity {  
    BMapManager mBMapMan = null;  
    MapView mMapView = null;  
    @Override  
    public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main);  
        mBMapMan = new BMapManager(getApplication());  
        mBMapMan.init("027FB8C5D701284490FF6C80E66AD7EAB37154C4", null);  
        super.initMapActivity(mBMapMan);  
        mMapView = (MapView)findViewById(R.id.bmapsView);  
        mMapView.setBuiltInZoomControls(true);  
        MapController mMapController = mMapView.getController();  
        GeoPoint point = new GeoPoint((int)(39.915 * 1E6), (int)(116.404 * 1E6));  
        mMapController.setCenter(point);  
        mMapController.setZoom(12);  
    }  
    @Override   
    protected void onDestroy() {  
        if(mBMapMan != null)  
        {  
            mBMapMan.destroy();  
            mBMapMan = null;  
        }  
        super.onDestroy();  
    }     
    @Override  
    protected void onPause() {  
        if (mBMapMan != null)  
        {  
            mBMapMan.stop();  
        }  
        super.onPause();  
    }     
    @Override  
    protected void onResume() {  
        if (mBMapMan != null)  
        {   
            mBMapMan.start();  
        }  
        super.onResume();  
    }  
    @Override  
    protected boolean isRouteDisplayed() {  
        return false;  
    }  
}

有什么想法解决这个问题吗？提前致谢！

Answer 1

com.example.adbaidumapdemo02.AdBaiduMapDemo02：java.lang.ClassNotFoundException：

您的AdBaiduMapDemo02.class在哪里？

Answer 2

您项目中的某个位置引用了Java Class Loader无法找到的类AdBaiduMapDemo02。

我建议您在项目中搜索“AdBaiduMapDemo02”

应用程序XXX意外停止。请再试一次
