Google map android API V2 crashed

Question

I want to load the google map API on my android. I try everything I search but it still crash. this is my MainActivity.java

package com.example.androidmapsv2;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;

import com.google.android.gms.common.GooglePlayServicesUtil;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;

public class MainActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        // Show the Up button in the action bar.
        getActionBar().setDisplayHomeAsUpEnabled(true);
        GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());

        GoogleMap map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();

    }

}

This is my layout activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >
    <fragment
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.SupportMapFragment"/>
</RelativeLayout>

This is my manifest

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="AIzaSyDr9xN8L3sF6W2ZRWmTR7q0lhTeOWhXEfQ" />
    </application>

</manifest>

UPDATED

i've tried to copy the google-play-services_lib to workspace and red mark disappear but it come another error. It missing the google-play-services_lib.jar (the lib folder name + .jar). how to fix it when i click the google-play-services_lib.jar, the remove button doesn't show up(like picture). However i try remove all Android Dependencies and import the others lib again. now it working, but still crash.

I've tried change

MainActivity extends Activity

To

MainActivity extends FragmentActivity

and the layout

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >
    <fragment
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.SupportMapFragment"/>
</RelativeLayout>

it appear another error. help me, now i'm out of solution for this

Finally, i solved my error. It caused by my eclipse (i guess). When you add the library class, it automatically appear "google-play-services_lib.jar", you don't have to do anything. I reinstall Eclipse and everything work fine

Answer 1

I also faces this kind of the problem,when first time coding for the map with API V2.

Just try using the extends with FragmentActivity instead of the Activity

you have to copy the project(goolge_play_services) into your workspace and then attach it to your project. In above image it show the cross red,so select it and remove and then after once again add attach the library with the project.

Answer 2

It is required to use SupportMapFragment if API version is below 11

<fragment
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.google.android.gms.maps.SupportMapFragment"/>

• Important

  Don't forget to extend your Activity with FragmentActivity

Answer 3

you have to copy the project(goolge_play_services) into your workspace and then attach it to your project.

What you are doing is importing the project and not checkmarking the copy the project into workspace due to which it showing you wrong mark in added libraries.

So just checkmark the the copy the project into workspace while importing the google_play_services project and then attach it to your project.

Answer 4

As here i can see that you are using the api level 8 and AFAIK the "Fragments" are supported from the 11.

So here you need to use the compatible library of the fragments.

And also make sure that you have also imported the library of the google-play-service in your workspace and added it in your application.

Answer 5

You need to edit your application's AndroidManifest.xml file, and add the following declaration within the element. This embeds the version of Google Play services that the app was compiled with.

<meta-data
    android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" />
