GooglePlayServices[GoogleMap API] - Can't see a map

For some reason i can't see any map using the google play services API.
activity_map:
package com.m.get.dl;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.OnMapReadyCallback;
import android.support.v4.app.FragmentActivity;
import android.os.Bundle;
public class Map extends FragmentActivity implements OnMapReadyCallback
{
MapFragment mapFragment;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_map);
mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.fragment_id);
mapFragment.getMapAsync(Map.this);
}
#Override
public void onMapReady(GoogleMap googleMap)
{
googleMap.setMyLocationEnabled(true);
googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL); // Setting map type
}
#Override
protected void onDestroy()
{
// TODO Auto-generated method stub
super.onDestroy();
}
#Override
protected void onPause()
{
// TODO Auto-generated method stub
super.onPause();
}
#Override
protected void onResume()
{
// TODO Auto-generated method stub
super.onResume();
}
#Override
protected void onSaveInstanceState(Bundle outState)
{
// TODO Auto-generated method stub
super.onSaveInstanceState(outState);
}
#Override
protected void onStop()
{
// TODO Auto-generated method stub
super.onStop();
}
}
I think the problem lies in the XML file - activity_map.xml:
<fragment
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:map="http://schemas.android.com/apk/res-auto"
class="com.google.android.gms.maps.MapFragment"
android:name="com.google.android.gms.maps.MapFragment"
android:id="#+id/fragment_id"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
Manifest:

<activity

</application>
</manifest>
So in the activity i get this screen instead of a map.
So is my fragment tag is wrong?

Check the server key you are using. Make sure you have used accurate SHA-1 and package name. Rest of the code looks good!
Also, check the log if you are getting any error like:
Authentication failed on the server...
This says your key is not correct.
Updated:
You will be getting this log after the 'Authentication failed...'
Ensure that the following Android Key exists: ...
You can get correct SHA-1 key and package name below this 'Ensure that...' error message.
Both are separated by ';'
And now create new API key and add this new key in Manifest file tag.
**Manifest:**
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="#string/google_maps_key" />
This will solve your problem!

Android Unity - change launcher activity

I have just started learning about Unity so this may seem like a stupid question.
I have made a small minigame that renders a character when the device camera sees a specific image. My problem is that I want to show some kind of menu before the unity activity is triggered.
For example in my code, I changed my launcher activity to be my main activity and when the start button in pressed then I would like that the unity activity would be triggered (and my device camera will open). Unfortunately it's not working (my app crashes when I press the button) and my logcat doesn't show anything.
This is my manifest

Any idea? Any help would be greatly appreciated!

You probably haven't listed UnityPlayerActivity in the AndroidManifest.xml file using the tags <activity></activity> e.g.

Orientation issue in Hybrid Android Application

Kindly help me in this problem.. i am working in the hybrid android mobile application.. it works correctly but when i changed the orientation the application gets restarted.... both in portrait and landscape...

} else {
System.out.println("Sorry, it failed three times so I give up.");
super.loadUrl("file:///android_asset/www/fail.html");
}
return;
}
}

If don't want your application to restart you have to declare that explicidly in the android manifest like this
<activity android:name=".MyActivity"
android:configChanges="orientation"
android:label="#string/app_name">
However this is not recommended and considered as last resort.
Here you can read more how you should handle configuration changes

I want somebody to help me with fortumo in app payment. Why does the app crash??

Suggest to call makepayment in onclick of button. this triggers the sms payment cycle.
EDIT
Suggest that you add PaymentActivity in your manifest along with fortumoactivity ie., both activities need to be declared.
