still error Android: Unable to start activity ComponentInfo{/com.}: android.view.InflateException: Binary XML file line Error inflating class fragment

Question

I created first version of my application using Google Maps Android v1 API. But now When I released my application for second version, Google map stopped working. I think it's because of it's deprecated.

So now I'm trying to create sample Android application to use Google Map using this link.

First I was trying with this code

But as I suggested to use SupportMapFragment with FragmentActivity, I changed my xml code to

<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"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >

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

    <fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_marginRight="150dp" />

</RelativeLayout>

and imported FragmentActivity instead of Activity, and now I'm getting error

Answer 1

You need an android:name="com.google.android.gms.maps.SupportMapFragment" inside your <fragment> tag.

The android:name attribute in the specifies the Fragment class to instantiate in the layout.

Update:

After you update your code, there is a ClassNotFoundException for com.google.android.gms.maps.SupportMapFragment.

So you also need to make sure you added reference library google-play-services.jar.
