Caused by: java.lang.IllegalStateException: The meta-data tag in your app's AndroidManifest.xml does not have the right value. Expected 7095000 but found 6587000. You must have the following declaration within the application element:

You need to Update the Google Play Service in Your Device or in Your
Emulator
Because the thing is that, you use the latest version of play service in development but you device have oldest one.
So the problem is come in picture.

you don't have the updated version. you need to update from SDK manager. if you work with android studio you can do it do it automatic by define in gradle file like this:
dependencies {
compile 'com.android.support:support-v13:21.0.3'
compile 'com.google.android.gms:play-services:6.5.87'
}
if you work with eclipse, you need to remove the oldest google play services and bring the new from android sdk/extras

Unable to load maps into an android(samsung) phone

Unable to load maps into an android(samsung) phone. It just displays grid cells without loading the maps. This is my first time developing an android application. Could you please help in what else needs to be done apart from the below steps.
Downloaded the android version(eclipse).
Installed all the required API's for google maps.
Set the manifest file.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

If you are using google map v2 then first create(check) api key.
You have to add google-play-services library.
<uses-sdk
android:minSdkVersion="12"
android:targetSdkVersion="17" />
<permission
android:name="com.example.package.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />

References:
link link2
Please refer link and change xml,java and manifext.xml
If you find any trouble then let me know.

In AndroidManifest.xml, add the following element as a child of the element, by inserting it just before the closing tag :
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="your_api_key"/>
You are missing
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
<uses-feature
android:glEsVersion="0x00020000"
android:required="true"/>
Few permissions are repeated remove them
Go through the steps in the link. I doubt you have followed the steps from the below link.
https://developers.google.com/maps/documentation/android/start.
You can also follow the tutorial in the link below
http://www.youtube.com/watch?v=awX5T-EwLPc
Edit :
You also require
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
You can also get rid of
<permission
android:name="com.example.package.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
