Im creating an application in which I have to show map when the button is clicked. 
我正在创建一个应用程序，我必须在单击按钮时显示地图。 But when the map button is clicked instead of showing map the application crash and it said "Unfortunately, 'Application' has stopped" here is my code: 但是当点击地图按钮而不是显示地图时应用程序崩溃并且它说“不幸的是，'应用程序'已停止”这里是我的代码：
java file: java文件：
package com.example.jamaattiming;
import android.os.Bundle;
import android.app.Activity;
//import android.app.FragmentTransaction;
import android.view.Menu;
import com.example.jamaat_times.R;
import com.google.android.gms.maps.GoogleMap;
//import com.google.android.gms.maps.MapFragment;
public class TagYourself extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tag_yourself);
/* MapFragment mMapFragment = MapFragment.newInstance();
FragmentTransaction fragmentTransaction =
getFragmentManager().beginTransaction();
fragmentTransaction.add(R.id.map, mMapFragment);
fragmentTransaction.commit();
GoogleMap maps;
maps=(((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap());*/
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.tag_yourself, menu);
return true;
}
}

Take a look at this line of your logcat: 看看你的logcat的这一行：
Caused by:
java.lang.SecurityException: The Maps API requires the additional following permissions to be set in the AndroidManifest.xml to ensure a correct behavior: 04-01 00:32:39.709:
E/AndroidRuntime(18546): <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> 04-01 00:32:39.709: E/AndroidRuntime(18546): at maps.e.ci.a(Unknown Source)
Looks like you forgot to add the permission: 您似乎忘了添加权限：
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
to your AndroidManifest xml file 到您的AndroidManifest xml文件
