地图在 Nexus 5X API 28 中崩溃，但在 Google PIXEL 2 XL API 27 中运行良好

Question

我已按照 Google 开发人员指南使用 Google 地图的 API 创建地图 activity。我的API密钥已经激活了，请问Nexus 5X崩溃的原因是什么。

共享我的 AndroidManifest.xml、MapActivity.java、google_maps_api.xml、activitymaps.xml 和 Gradle 模块：-

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

        <activity
            android:name=".MapsActivity"
            android:label="@string/title_activity_maps">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

MapsActivity.java

package com.example.kiit.mapone;

import android.support.v4.app.FragmentActivity;
import android.os.Bundle;

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;

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

    private GoogleMap mMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_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);
    }

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

        // Add a marker in Sydney and move the camera
        LatLng sydney = new LatLng(-34, 151);
        mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
        mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
    }
}

google_maps_api.xml

<resources>
    <string name="google_maps_key" templateMergeStrategy="preserve" translatable="false">KEY IS HERE</string>
</resources>

出于安全原因，我已将此文件中的 API 密钥替换为 "KEY IS HERE"

activity_maps.xml

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MapsActivity" />

Answer 1

在你的manifest里面添加<application>

<uses-library
        android:name="org.apache.http.legacy"
        android:required="false" />

编辑

您的应用程序标签应如下所示

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

    <meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="@string/google_maps_key" />

    <activity
        android:name=".MapsActivity"
        android:label="@string/title_activity_maps">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

   <uses-library
        android:name="org.apache.http.legacy"
        android:required="false" />

</application>
