我在logcat中有这个错误：
Activity com.mypackage.app.MainActivity has laked IntentReceiver com.mypackage.app.MainActivity$100000000@4202adb8 that was originally registred here. Are you missing a call to unregisterReceiver()?
该服务的代码是：

// IntentFilter mIntentFilter = new IntentFilter();
// mIntentFilter.addAction(Intent.ACTION_BATTERY_CHANGED);
// registerReceiver(mBI, mIntentFilter);
// After registering mBI, another update is immediately processed.
// So, skip double update processing.
return;
}
//update widget views and database
updateWidget(getApplicationContext(), intent);
}
@Override

}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (debug)

handleCommand(intent);
// The service has to be running otherwise the broadcast ACTION_BATTERY_CHANGED wont be received anymore
// thats why it returns START_STICKY

}
@Override

// TODO Auto-generated method stub
return null;
}
}
}
我找不到错误..我也发布了清单：
<service android:name=".UpdateService" />
<receiver android:name=".BatteryInfo" android:label="BatteryInfo">
<intent-filter>
<action android:name="android.intent.action.BATTERY_CHANGED" />
</intent-filter>
</receiver>
<activity
android:name=".AndroidBatteryActivity"
android:label="@string/app_name" >
</activity>
<activity android:name="org.achartengine.GraphicalActivity" >
</activity>
任何帮助？
