Java “我的地图”活动加载后立即崩溃

访问“地图”活动时，它会崩溃。我试着用一个通用的“地图”活动来切换这个活动，但这个活动确实有效，我已经返回到以前的版本，我知道这个版本完全无效

这是Android Java：

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

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

        buttonLogout.setOnClickListener(new View.OnClickListener() {

        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();

        super.onStop();

        String userID = FirebaseAuth.getInstance().getCurrentUser().getUid();

        GeoFire geoFire = new GeoFire(ref);

    }
}

我是Android开发新手，所以我不确定它对调试此类问题是否特别重要，但这里是布局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>

我不确定我是否应该分享AndroidManifest，但我觉得这很重要

还有，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，我将不胜感激（比如，我需要切换设置或安装额外的东西吗？）

谢谢

您能检查“运行”选项卡中的错误而不是Logcat吗。如果应用程序一启动就崩溃，“运行”选项卡中可能存在日志。

logcat中的错误是什么？您试图在logcat中查看是否存在崩溃的错误日志？@MMG java.lang.SecurityException:我的位置需要权限访问\u FINE\u location或访问\u rough\u location这是错误，但我在清单中已经有此权限…好的，看我的answer@MMG感谢您对帮助我的兴趣，解决方案是该应用未被授予权限（我没有为用户编写代码以授予权限）。当我在应用程序设置中手动授予权限时，它会起作用。再次感谢您的支持！可以java.lang.SecurityException:my location需要权限访问\u FINE\u location或ACCESS\u Rough\u location我已经在清单中添加了权限，所以我不确定它为什么会抛出此消息…位置权限是危险的权限。它们需要运行时权限授予。如果未给出，将引发securityexceptions。您可以引用此源来执行此操作。谢谢你的文章！我需要授予权限！我进入应用程序设置并手动授予权限，它成功了！我需要了解如何向用户请求权限，但这就是它不起作用的原因（我实际上不记得昨天授予了权限，所以我不确定它是如何工作的）。谢谢你的支持！很高兴我能帮忙。
