我的地图活动在加载后立即崩溃[重复]

Question

访问地图活动时，它会崩溃。我尝试使用通用的 Maps Activity 来切换 Activity，它确实有效，但我已经回滚到以前的版本，但我知道该版本无济于事。

这是 Android Java：

import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.core.app.ActivityCompat;
import androidx.fragment.app.FragmentActivity;

import android.Manifest;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.graphics.Camera;
import android.location.Location;

import com.firebase.geofire.GeoFire;
import com.firebase.geofire.GeoLocation;
import com.google.android.gms.location.LocationListener;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApi;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.common.internal.GoogleApiAvailabilityCache;
import com.google.android.gms.location.LocationRequest;
import com.google.android.gms.location.LocationServices;
import com.google.android.gms.maps.CameraUpdateFactory;

import com.google.android.gms.maps.model.MarkerOptions;
import com.google.firebase.auth.FirebaseAuth;
import com.google.firebase.database.DatabaseReference;
import com.google.firebase.database.FirebaseDatabase;

public class DriverMapsActivity extends FragmentActivity implements OnMapReadyCallback, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, LocationListener {

    private GoogleMap mMap;
    GoogleApiClient mGoogleApiClient;
    Location driverLastLocation;
    LocationRequest driverLocationRequest;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_driver_maps);
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);

        Button buttonLogout = findViewById(R.id.buttonLogout);

        buttonLogout.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                FirebaseAuth.getInstance().signOut();
                Intent intent = new Intent(DriverMapsActivity.this, MainActivity.class);
                startActivity(intent);
                finish();
                return;
            }
        });
    }

    @Override
    public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;

        buildGoogleApiClient();
        mMap.setMyLocationEnabled(true);

    }

    protected synchronized void buildGoogleApiClient(){
        mGoogleApiClient = new GoogleApiClient.Builder(this).addConnectionCallbacks(this).addOnConnectionFailedListener(this).addApi(LocationServices.API).build();
        mGoogleApiClient.connect();
    }

    @Override
    public void onLocationChanged(Location location) {
        driverLastLocation = location;

        LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());

        mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
        mMap.animateCamera(CameraUpdateFactory.zoomTo(11));

        String userID = FirebaseAuth.getInstance().getCurrentUser().getUid();
        DatabaseReference ref = FirebaseDatabase.getInstance().getReference("driversClear");

        GeoFire geoFire = new GeoFire(ref);
        geoFire.setLocation(userID, new GeoLocation(location.getLatitude(), location.getLongitude()));
    }

    @Override
    public void onConnected(@Nullable Bundle bundle) {
        driverLocationRequest = new LocationRequest();
        driverLocationRequest.setInterval(1000);
        driverLocationRequest.setFastestInterval(2000);
        driverLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);

        LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, driverLocationRequest, (com.google.android.gms.location.LocationListener) this);
    }

    @Override
    public void onConnectionSuspended(int i) {

    }

    @Override
    public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {

    }

    @Override
    public void onStop(){
        super.onStop();

        String userID = FirebaseAuth.getInstance().getCurrentUser().getUid();
        DatabaseReference ref = FirebaseDatabase.getInstance().getReference("driversClear");

        GeoFire geoFire = new GeoFire(ref);
        geoFire.removeLocation(userID);
    }
}

我是 Android Dev 的新手，所以我不确定它是否对调试这类问题特别重要，但这是布局 XML 的事情

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".DriverMapsActivity" >


    <Button
        android:id="@+id/buttonLogout"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Logout" />

    <fragment
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    </FrameLayout>

我不确定是否应该分享 AndroidManifest，但我觉得它很重要

            </intent-filter>

    </application>

</manifest>

另外，如果有人能告诉我为什么内置调试器没有通知我这个错误，我会很感激（因为我需要切换设置或安装额外的东西吗？）

谢谢

您能否检查“运行”选项卡是否有错误，而不是 Logcat。如果应用一启动就崩溃，日志可能会显示在“运行”选项卡中。
