Question

I am new in Google Map and so many things aren’t clear enough to me for that reason.So i expect some expert’s direction on this regard.I read This Guide and did everything what it says.I use google map api v2 and get a map key.Then i make a sample project following that link and select target version android 2.2(while running the project).But a list of error occurs after running then example in eclipse android emulator.My logcat view shows:

My activity.java is:

package com.googleMapApp;

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


public class LocationProfileManagerActivity extends Activity {
    /** Called when the activity is first created. */
    //private GoogleMap map;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        //map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

     }
}

Sorry for this lengthy description,but i want to show you exactly what i did.I think as a newcomer i did a lot of mistake on this way.so i expect someone will guide me that.

Answer 1

You are using features only available in later APIs, namely Fragment. If you want to compile to support 2.2, you need to include the Support Library in your project. You will also have to make the following changes to use support fragments instead of regular fragments —

In main.xml, change

class="com.google.android.gms.maps.MapFragment"/>

to

class="com.google.android.gms.maps.SupportMapFragment"/>

and in your activity.java, change

public class LocationProfileManagerActivity extends Activity {

to

public class LocationProfileManagerActivity extends FragmentActivity {
