LOG CAT Error on Google Maps API using basic tutorial

I submitted an similar question earlier on a more advanced project, so I thought I would simplify things by using the maps API tutorial provided by google to try and replicate the error I was getting, and I get the same error! Good and bad, at least I know it's not my project causing the error.
Now I just need to figure out why I am getting this error! I am new to programming but I followed this tutorial here verbatum:
https://developers.google.com/maps/documentation/android/start
Here is the error I am getting:

Here is my simple MainActivity.java
package com.example.test;
import android.app.Activity;
import android.os.Bundle;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
here is my simple activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:name="com.example.test.MainActivity"/>
Here is my manifest:

</application>
</manifest>
The only thing I can think of is that my manifest file is improperly set up. But I followed the instructions and Eclipse didn't give me an error on it. I am up in arms here trying to figure this out. Any help would be appreciated.

Your logcat clearly said
Caused by: java.lang.IllegalStateException: The meta-data tag in your app's AndroidManifest.xml does not have the right value. Expected 4242000 but found 0. You must have the following declaration within the <application> element: <meta-data android:name="com.google.android.gms.version" android:value="#integer/google_play_services_version" />
03-24 20:47:03.244: E/AndroidRuntime(6250): at com.google.android.gms.common.GooglePlayServicesUtil.n(Unknown Source)
Add the Google Play services version to your app's manifest
Edit your application's AndroidManifest.xml file, and add the
following declaration within the element. This embeds the version of
Google Play services that the app was compiled with.
You need to add <meta-data> under <application> tag into your AndroidManifest.xml
....<application>
<meta-data android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
</application>
This is because latest google play services requires a version name, which is to be mentioned using <meta-data .. /> inside AndroidManifest.xml
....<application>
..............
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="Key" />
<meta-data android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
</application>
Also Extends your Activity to FragmentActivity
MainActivity extends FragmentActivity

You need to add the below as a child of application tag as mentioned in the other answer.
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
Also you have
<uses-sdk
android:minSdkVersion="8"
So change this
public class MainActivity extends Activity {
to
public class MainActivity extends FragmentActivity {
Since you use SupportMapFragment you need to use FragmentActivity which is the base class for support based fragments.
Also change this
class="com.google.android.gms.maps.SupportMapFragment"
android:name="com.example.test.MainActivity"/> // remove this
to
class="com.google.android.gms.maps.SupportMapFragment"/>

Put both meta tag with your API key....in between applicationTag.
Also add permission tag with your package name which you use in Google console in your AndroidManifest.xml.
<permission
android:name="com.xyz.permission.MAPS_RECEIVE"
android:protectionLevel="signature"/>
<uses-permission android:name="com.xyz.permission.MAPS_RECEIVE"/>
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
.....
.....
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="Put Your API Key here"/>
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
</application>
Extend your class activity to fragment activity use below
public class MainActivity extends FragmentActivity
Insted of this
public class MainActivity extends Activity

You are missing following lines in your Manifest file,
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
Please write these lines before your MAP-API Key tag, inside the tag.
Once you will complete these changes you will get Fragment error as you are using latest version of Map but you are using Activity inside your code, So you need to change following as well,
Extends your Activity to FragmentActivity
MainActivity extends FragmentActivity

Edit your application's AndroidManifest.xml file, and add the following declaration within the element. This embeds the version of Google Play services that the app was compiled with.
This is a new requirement as of the updated google play services which is rev 13 i guess.
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
https://developers.google.com/maps/documentation/android/start#getting_the_google_maps_android_api_v2
There is no need for
<permission
android:name="com.example.gmapsapp.permission.MAPS_RECEIVE"
android:protectionLevel="signature"/>
and this
<uses-permission android:name="com.example.gmapsapp.permission.MAPS_RECEIVE"/>
Refer Specifying permission in the above link

try to put
<meta-data
android:name="com.google.android.gms.version"
android:value="key" />
inside your application tag, in AndroidManifest.xml

Caused by: java.lang.IllegalStateException: A required meta-data tag in your app's AndroidManifest.xml does not exist.
You must have the following declaration within the <application> element:
<meta-data android:name="com.google.android.gms.version" android:value="#integer/google_play_services_version" />
Your log telling you everything :
Add the version code of google play services inside <application> i.e. before </application> inside AndroidManifest.xml
<meta-data

</meta-data>

You can try this code, if you know the location name you want to display in map. It worked for me.
Geocoder geocoder;
List<Address> addresses = null;
geocoder = new Geocoder(this, Locale.getDefault());
try {
//getFromLocationName returns array of address, it takes 2 parameter one place name and count of result
addresses = geocoder.getFromLocationName("Place name", 1);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
latitude = addresses.get(0).getLatitude();
longitude = addresses.get(0).getLongitude();
String label = "SomePlace";
String in = "geo:" + latitude + "," + longitude;
String query = latitude + "," + longitude + "(" + label + ")";
String ey = Uri.encode(query);
String uriLoc = in + "?q=" + ey+ "&z=16";
Log.d(uriLoc, "no log");
Uri uri = Uri.parse(uriLoc);
Intent intent = new Intent(android.content.Intent.ACTION_VIEW, uri);
startActivity(intent);

Unable to instantiate activity error? how to solve it?

I made an App. and since I just wanted to test some functions before adding them to the App,
I decided to copy my project into a new Project. When I tried to run the new project, the app crashes and the log-cat output is as follows.

Check your Manifest file, if the activity is to be declared.
for Ex:
<application>
<activity android:name=".MyActivity" android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

Look through all the files in your new project and make sure they aren't referencing classes from the old project.

I think I found the solution, i should have checked that, the package name of the new project is included in the manifest file as for an example
"package="com.androidbook.MPTest" ..
my mistake is the i used the package name of the old project as a package name of the new project.

Impossible to instantiate an OsmDroid MapView

I'm trying to use OSMdroid for a project, and i'm utterly unable to make the simplest code work.
Well, a few days ago i was able to display maps and so on, and now i can't even instantiate a MapView.
I reduced the code to its sipmlest form.
I work with eclipse. I downloaded osmdroid-android-3.0.5.jar and slf4j-android-1.5.8.jar, and i included them in the project by adding lines to the classpath file
<classpathentry kind="lib" path="lib/osmdroid-android-3.0.5.jar"/>
<classpathentry kind="lib" path="lib/slf4j-android-1.5.8.jar"/>
Or by right clicking on them then Build Path-> Add to build path (both gave the same result, anyway)
Then i typed this code:
import android.app.Activity;
import org.osmdroid.tileprovider.tilesource.TileSourceFactory;
import org.osmdroid.util.GeoPoint;
import org.osmdroid.views.MapController;
import org.osmdroid.views.MapView;
import android.os.Bundle;
public class TestMapActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
MapView mv=new MapView(this,256);
}
}
And i get a bug when running it on the emulator:

When i comment out the "MapView mv=new MapView(this,256);" it works, so i don't understand why the mapview can't be instantiated.
Any idea on this?
Thank you for your attention.

Change Folder name "lib" to "libs" and put all jar files in that folder and Charge path of jar
files to "libs" folder. I am not sure but I think it will work.

Try to use the 3.0.7 and clean the project.
Let me know.
