XML Error when using Fragment tag in android

Question

I am trying to implement fragment tag, in my code so that I can use it with GoogleMap API. However just at the outset i am getting stuck because of an error "Binary XML File Line". I tried searching it in the forum but I was not able to solve it. Kindly help me understand this problem.

I am attaching all the files here my activity_main.xml

<LinearLayout 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="com.example.mapdemo.MainActivity" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

</LinearLayout>

My activity_map.xml file goes as

  <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <LinearLayout 
        android:orientation="horizontal"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">
        <TextView 
            android:text="Loc:"
            android:textSize="20sp"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="left|center_vertical"
            />

        <EditText 
            android:id="@+id/edt_locationName"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center|center_vertical"
            android:ems="10"/>
        <Button 
            android:id="@+id/btn_GetLocation"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Go"
            android:layout_gravity="right|center_vertical"
            android:onClick="geoLocate"/>

    </LinearLayout>

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

</LinearLayout>

My main java file goes as

    package com.example.mapdemo;

import android.support.v4.app.FragmentActivity;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;


public class MainActivity extends FragmentActivity {

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


    @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;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

Answer 1

try to put the fragment inside the linearLayout tag

Answer 2

In your MainActivity, add the following import statement

import android.support.v4.app.Fragment;

Edit: I'm not sure if this will work, but try changing your fragment tag to this

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