应用程序崩溃意图从谷歌地图开始

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);


        }

    });

当我在我的计算机上设置的模拟器上运行此代码时，它会显示“除非您更新 Google Play 服务，否则此应用程序将无法运行。但是当我在物理设备上运行它时，它会超时并显示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差异如此之大？

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class StartingPoint extends Activity {

double numDrinks;
int counter;

    counter = 0;
    bacIntent = (Button) findViewById(R.id.bacIntent);
    maps = (Button) findViewById(R.id.Maps);
    drinks = (Button) findViewById(R.id.drinks);


    bacIntent.setOnClickListener(new Button.OnClickListener(){
        @Override
        public void onClick(View v){


            try{
                Intent openBac = new Intent("com.schweigert.drinkingbuddy.BloodAlcoholContent");
                startActivity(openBac);
            }
            catch(Exception e)
            {
                display.setText("my d" + e);
            }
            }



    });

    maps.setOnClickListener(new Button.OnClickListener(){

        @Override

            catch(Exception e){
                display.setText("my d"+ e);
            }
        }

    });

    drinks.setOnClickListener(new Button.OnClickListener(){

            try{

                startActivity(openDrinkMenu);
            }
            catch(Exception e){
                display.setText("my d:" + e);
            }
        }

    });


}
}

所以我有一个 try catch 与一个不再存在的 textview 交互，然后我的清单设置不正确。感谢 Shivan 的帮助。
