[访问“地图活动”后，它崩溃了。我已经尝试过使用可以正常工作的通用Maps Activity来关闭Activity，并且我已回滚到以前知道的所有版本，但都无济于事。
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.GoogleMap; import com.google.android.gms.maps.OnMapReadyCallback; import com.google.android.gms.maps.SupportMapFragment; import com.google.android.gms.maps.model.LatLng; 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，所以我不确定调试此类问题是否特别重要，但这是布局XML的问题
<?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>而且我不确定是否应该共享AndroidManifest，但我觉得它很重要

谢谢

您是否可以检查'运行'选项卡是否有错误，而不是Logcat。如果应用程序在启动后立即崩溃，则“运行”标签中可能存在日志。
