Question

地图活动的Java代码

package com.schweigert.drinkingbuddy;

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


public class BarMaps extends Activity {



protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.barmaps);


}
}

XML代码

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/map"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:name="com.google.android.gms.maps.MapFragment" >


</fragment>

启动意图的Java代码

    maps.setOnClickListener(new Button.OnClickListener(){

        @Override
        public void onClick(View v) {


                Intent openMap = new Intent("com.schweigert.drinkingbuddy.BarMaps");
                startActivity(openMap);


        }

    });

当我在我的模拟器上运行此代码时，我已在我的计算机上设置它会显示“除非您更新Google Play服务，否则此应用程序不会运行。但是当我在物理设备上运行它时，它只是超时而且说该应用程序已停止工作。为什么我的模拟器和物理设备之间的错误有这样的差异？

所以我尝试了一个与不再存在的textview进行交互的catch，然后我的清单设置不正确。感谢Shivan的帮助。
