Update Your Code .I hope it helps you . It working for me !

package com.sahaab.muslimzone.activity;

import com.sahaab.android.muslimzone.test.R;

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

public class IqamahActivity extends FragmentActivity {

GoogleMap map;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_iqamah);
map =((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.iqamah_map)).getMap();

    }
}

Change your XML

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

  • @SimplePlan Sir : I have faced same problem . Then use it .Actually SupportMapFragment belongs to the v4 support library, contrary to the default MagFragment that is a native component in Android. – IntelliJ Amiya Jun 27 '14 at 06:06

    @A Ya that's reason. but another reason is if your `minsdk<12` then you should used `SupportMapFrgament` for Backward compability Support and your activity should also extends `FragmentActivity` for that. – M D Jun 27 '14 at 07:19
  • @SimplePlan Yes yes .Glad to receive your information . – IntelliJ Amiya Jun 27 '14 at 07:23

Amiya is right, you need to use FragmentActivity to use Fragments.

To find out the difference between Activity and FragmentActivity, this might help!

if you're targeting API 12 and above, you can use MapFragment. Otherwise, use SupportMapFragment.

SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
