Android工程运行模拟器是出错提示has stop unexpectedly

代码
package com.mybaidumap;

import com.baidu.mapapi.map.MapView;

import android.app.Activity;
import android.os.BatteryManager;
import android.os.Bundle;

public class BaiduMapActivity extends Activity {
private BatteryManager mBMapMan = null;
private MapView mMapView = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mBMapMan=new BatteryManager();
try {
mBMapMan.wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
//注意：请在试用setContentView前初始化BMapManager对象，否则会报错
setContentView(R.layout.main);
mMapView=(MapView)findViewById(R.id.bmapsView);

}

// 重写activity生命周期方法以对mapview和map manager进行管理
@Override
protected void onDestroy(){
mMapView.onDestroy();

super.onDestroy();
}
@Override
protected void onPause(){
mMapView.onPause();

super.onPause();
}
@Override
protected void onResume(){
mMapView.onResume();

super.onResume();
}
}

看看Logcat里面的错误信息。

不明白啊 = =！
