Error Andoid Studio : Fragment cannot be converted to SupportMapFragment

Question

I have an error while trying to run the Signal application for Android. The error is as the following :

error: incompatible types: Fragment cannot be converted to SupportMapFragment
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);

And it is found in the PlacePickerActivity.java in the following line :

SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);

Can someone help me with this?

Answer 1

According to Android docs: findFragmentById(int)

The findByFragmentId() function returns a Fragment, you cannot cast it to a SupportMapFragment.

You can try something like this:

SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map).getMap();
