这个错误一直存在。(我确保“Google Maps Android API v2”是打开的。)
这是 MainActivity.java:
package com.example.maptest;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
public class MainActivity extends FragmentActivity {
@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;
}
}
显现:

请帮忙!我不确定出了什么问题……尽管我最终还是遵循/组合了各种教程,因为它们都没有单独工作。
