maps api v2 android: Binary XML file line #2 error

Question

I have been toiling with the Google-maps API for Android v2 for days now, and cannot figure out how to get this activity working, here is the layout file activity_main.xml:

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

Here is MainActivity.java:

package com.gabe.locator;

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

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}

And my manifest file:

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.gabe.locator"

            android:theme="@style/AppTheme" >
            <activity

                </intent-filter>
            </activity>
        </application>

    </manifest>

here is my last error trace:

Does anyone have any idea what is causing the crash each time I run this on Cyanogenmod for HTC One S, with android 4.3.1?

Thanks! Gabe

Answer 1

As per Documentation

Note: The Google Maps Android API requires API level 12 or higher for the support of MapFragment objects. If you are targeting an application earlier than API level 12, you can access the same functionality through the SupportMapFragment class. You will also have to include the Android Support Library .

Add this both

  <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />
    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="AIzaSyDW3bQEXEHW956EiLMhgvaXBQMakRa7i6E" />

Under <application> tag in manifest.xml file.

And extends your Activity to FragmentActivity .

Answer 2

Use SupportMapFragment in layout.xml

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

Also extend as FragmentActivity and not as Activity
