Google Map v2 hangs with grey screen on load

Question

I am trying to display Google map inside child fragment on my emulator. But problem is that emulator freezes along with toast displayed continuously while map is loaded like this:

I have checked my manifest file, recreated API key and debug.keystore both. But still it's not working. Please tell me how to tackle with this problem. Thanks.

**Note: ** I am testing on Genymotion emulator - Galaxy S2 API 10(2.3.7). Google play services are already installed on emulator.

Answer 1

if you create your debug.keystore then have you export your app with this same keystore path?

i think you don't have to export your app..

Please export your app with same keystore which is created ..

i hope you solved your problem.

Answer 2

Change your map_fragment.xml

<?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:gravity="center"
    android:orientation="vertical" >
 <FrameLayout android:id="@+id/map"
   android:layout_width="match_parent"
   android:layout_height="0dp"
   android:layout_weight="1.03"
   android:name="com.google.android.gms.maps.SupportMapFragment" />

</LinearLayout> 

to

<?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:gravity="center"
        android:orientation="vertical" >

     <fragment android:id="@+id/map"
       android:layout_width="match_parent"
       android:layout_height="0dp"
       android:layout_weight="1.03"
       android:name="com.google.android.gms.maps.SupportMapFragment" />

    </LinearLayout>
