google maps v2 illegalStateException

java.lang.IllegalStateException: Not connected. Call connect() and wait for onConnected() to be called.

This happens when you request for locationupdates before the actual location connection is established. Instead use a boolean variable to check if connection is established or call for locationupdates as below in onConnected.

@Override

public void onConnected(Bundle connectionHint) {

Toast.makeText(this, "Connected", Toast.LENGTH_SHORT).show();

mLocationClient.requestLocationUpdates(mLocationRequest, this);

}
