谷歌地图不会发布

Question

我写这封信是希望你能帮助我。出于某种原因，当我单击按钮时，我的应用程序不会启动谷歌地图，而是会将我发送回上一个活动/页面。当我再次按下该按钮时，应用程序会崩溃。

JAVA类（crkvalokacijamape.java）

import android.os.Bundle;
import android.view.WindowManager;

import androidx.annotation.NonNull;
import androidx.appcompat.app.AppCompatActivity;
import androidx.fragment.app.FragmentActivity;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;


public class crkva_lokacijamape extends FragmentActivity implements OnMapReadyCallback {

    GoogleMap map;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.crkva_lokacijamape);
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map1);
        mapFragment.getMapAsync(this);

    }

    @Override
    public void onMapReady(@NonNull GoogleMap googleMap) {

        map = googleMap;

        LatLng CrkvaSvetogPetraIPavla = new LatLng(43.03570877101472, 19.744756790194163);
        map.addMarker(new MarkerOptions().position(CrkvaSvetogPetraIPavla).title("CrkvaSvetogPetraIPavla"));
        map.moveCamera(CameraUpdateFactory.newLatLng(CrkvaSvetogPetraIPavla));
    }
}
