Question:

In my application I am using google map programmatically, but when I call getMap() it returns null. even I have tried onActivityCreated() but still it returns null. somebody please help me.. Here is my code,

public void callMap() { try { int status = GooglePlayServicesUtil .isGooglePlayServicesAvailable(mActivity); if (status == ConnectionResult.SUCCESS) { Log.d("sreedhu", "Google Play Service Available"); gmo = (new GoogleMapOptions()).zoomControlsEnabled(true) .rotateGesturesEnabled(true); mapFragment = SupportMapFragment.newInstance(gmo); map=mapFragment.getMap(); manager=getFragmentManager(); FragmentTransaction fragmentTransaction = manager .beginTransaction(); fragmentTransaction.add(R.id.mapFragmentHole, mapFragment); fragmentTransaction.commit(); manager.executePendingTransactions(); mapFragment=getMap(); } else if (GooglePlayServicesUtil.isUserRecoverableError(status)) { ErrorDialogFragment.newInstance(status).show( getFragmentManager(), "errorDialog"); } else { Toast.makeText(mActivity, "Google Map v2 not available", Toast.LENGTH_LONG).show(); mActivity.popFragments(); } } catch (Exception e) { Log.d("sreedhu", "play" + e.toString()); } }

executePendingTransactions seems not work like you expect it.

When MapFragment is created from code, you won't get GoogleMap from it until its onCreateView is called.

You need to call map=mapFragment.getMap(); and all code after it in onStart or onResume.

Finally, I got the fix for this problem...

I include this below piece of snippet on onCreateView which solved my problem,

SupportMapFragment mFragment; mFragment = new SupportMapFragment() { @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); if ((map = mFragment.getMap()) != null) { setUpMap(); } } };

Once the map is prepared the SuppotMapFragment's onActivityCreated will get called there you can setup your map.
