我有此代码用于在 android 设备上显示地图，但在“应用程序地图（进程 com.example.maps）已意外停止。”对话框中显示以下错误。即使按照 developer.google.com/maps 上给出的分步程序进行操作，上述给出的错误也会显示。
package com.example.maps;
import android.os.Bundle;
import android.app.Activity;
//import android.view.Menu;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
/* @Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}*/
}
这是布局......
<?xml version="1.0" encoding="utf-8"?>

这是 LogCat 视图.....
