So, perhaps you don't need a map here to send two simple values:

Try this:

Intent intent = new Intent(this, MapActivity.class);
intent.putExtra("longitude", mLongitude);
intent.putExtra("latitude", mLatitude);
startActivity(intent);

Then to extract your values:

Intent intent = getIntent();

double mLongitude = intent.getExtras().getDouble("longitude);
double mLatitude = intent.getExtras().getDouble("latitude");

Now you should have your values as needed!!

I hope this helps you!

sir but i have alot of values which i recieved through json this method i think work for just 2 values is there any way to send array to MApactivity – Naveed Abbas Apr 14 '16 at 19:49
The best approach here would then be to store your data in a local database and then simply go to the next activity and query your database simply and display the data to the user. That is what I would do – Eenvincible Apr 14 '16 at 19:53
