Add Activity into your manifest.xml because you need to give all path if your Activity located into different package.
<activity
android:name="com.mamun.tasktest.MapsActivity"
android:label="MapActivity" >
</activity>
And/or is your Activity belong to the same package then add simply
<activity android:name=".MapsActivity"></activity>
For more information go to:http://developer.android.com/guide/topics/manifest/manifest-intro.html

This is incorrect:
<activity android:name="MapsActivity"></activity>
You need to give full or relative path like this:
<activity android:name="com.mamun.tasktest.MapsActivity"></activity>
or
<activity android:name=".MapsActivity"></activity>

Replace your this tag in manifest
<activity android:name="MapsActivity"></activity>
by :
<activity android:name=".MapsActivity"></activity>
you should specify your full package name while declaring your activity into manifets.
See this link for reference:-
Add a new activity to the AndroidManifest?

You just forget to place a DOt (.) before MapsActivity. So, without that Dot (.) your class path looks like...
com.mamun.tasktestMapsActivity.java
But, it should be as....
com.mamun.tasktest.MapsActivity.java
Now, change this line of your Manifest...
<activity android:name="MapsActivity"></activity>
to...
<activity android:name=".MapsActivity"></activity>

I got the solution....The line "" should be inside application not inside directly on manifest.Like as below....

Bing maps on Android emulator works but not on device

I've set up the http://bingmapsandroidsdk.codeplex.com/ to try bing maps instead of google maps on Android. Because I was unable to set that up.
I'm able to run Bing maps on my emulator but I'm unable to run it on my device(Galaxy S2).
I have a wifi connection on my phone but I'm still unable to get past the load screen.
I also checked this question but it doesn't solve the problem Working on Emulator but not on the real Android device
So my code:
Manifest
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.CALL_PHONE"/>
<uses-permission android:name="android.permission.ACCESS_GPS"></uses-permission>
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="15"/>
<application android:icon="#drawable/bingmaps_icon" android:label="#string/app_name" android:allowBackup="false">
<activity android:name=".MainActivity"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="SplashActivity"></activity>

Osm tiles not shown on android app

I'm trying to make an app that will display an offline map with some clickable points on it.

and i added this to my manifest file:

Im a newbe in osmdroid :) But I had the same Problem.. In my case my EmulatorDevice was configured with no SDCard

Drag and Drop pin on google map manually and get Longitude & Latitude accordingly

In Google Maps, I'm dropping a pin on user's current location but now I want to give another functionality to user that he can drag that pin manually and drop anywhere on the map, also by the time he drops the pin manually I can receive a callback which gives me the Longitude and Latitude of that position where user drops that pin.
If you can give me some examples it will be greatly appreciable.

In the last few days I finally found how to implement those functions you described and because there was no answer in this question, I decided to post what I found even though there has been a long time since you asked and you may found another answer by yourself.
So, I used the code of this git. I managed to do all that you want except the callback that I didn't try it in that way. I am getting the position of the pin after pressing a button.
There is no need to post my AndroidManifest because I read that you had no problem with displaying your location, so the permissions needed were fine.
The only thing that was required to do, was to create an activity named MapsActivity.
This is the whole content of it:
import com.google.android.gms.maps.*;
import com.google.android.gms.maps.model.*;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageButton;
import android.widget.Toast;
import common.logger.Log;
public class MapsActivity extends Activity implements
OnMapReadyCallback, GoogleMap.OnInfoWindowClickListener,
GoogleMap.OnMarkerDragListener {
LatLng position = new LatLng(34.6767, 33.04455);
final Marker marker_final = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
MapFragment mapFragment = (MapFragment) getFragmentManager()
.findFragmentById(R.id.
map);
mapFragment.getMapAsync(this);
ImageButton returnback = (ImageButton)findViewById(R.id.returnback);
returnback.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(MapsActivity.this.getApplicationContext(), position.latitude + ":" + position.longitude, Toast.LENGTH_LONG).show();
}
});
}
#Override
public void onMapReady(GoogleMap map) {
map.setMyLocationEnabled(true);
map.moveCamera(CameraUpdateFactory.newLatLngZoom(position, 13));
CameraUpdate zoom = CameraUpdateFactory.zoomTo(15);
map.animateCamera(zoom);
map.addMarker(new MarkerOptions()
.title("Shop")
.snippet("Is this the right location?")
.position(position))
.setDraggable(true);
// map.setInfoWindowAdapter(new PopupAdapter(getLayoutInflater()));
map.setOnInfoWindowClickListener(this);
map.setOnMarkerDragListener(this);
}
#Override
public void onInfoWindowClick(Marker marker) {
Toast.makeText(this, marker.getTitle(), Toast.LENGTH_LONG).show();
}
#Override
public void onMarkerDragStart(Marker marker) {
LatLng position0 = marker.getPosition();
Log.d(getClass().getSimpleName(), String.format("Drag from %f:%f",
position0.latitude,
position0.longitude));
}
#Override
public void onMarkerDrag(Marker marker) {
LatLng position0 = marker.getPosition();
Log.d(getClass().getSimpleName(),
String.format("Dragging to %f:%f", position0.latitude,
position0.longitude));
}
#Override
public void onMarkerDragEnd(Marker marker) {
position = marker.getPosition();
Log.d(getClass().getSimpleName(), String.format("Dragged to %f:%f",
position.latitude,
position.longitude));
}
}

If anything else is required let me know.

Assuming the other person will also have your app installed, you could create a BroadcastReceiverwhich would respond to the android.provider.Telephony.SMS_RECEIVED action. The receiver should implement onReceive, detect if the message originated from your application (use some special key in the message body i guess?), extract the message and originating phone number from the extras in the received Intent, then trigger a location listener which would then send an SMS back...
The same BroadcastReceiver could also detect if the message has latitude/longitude in it, store the coordinates in some persistent storage, and send a broadcast intent to tell your MapActivity to update it's map with the new coordinates...
