Android应用加载ArcGIS地图时崩溃问题求助

问题场景 #

开发Android应用加载ArcGIS Online地图，启动后地图加载阶段随即崩溃，核心报错为NoClassDefFoundError: org.apache.hc.core5.http.message.BasicNameValuePair。

MainActivity代码 #

public class MainActivity extends AppCompatActivity {

    private MapView mMapView;
    private ArcGISMap wenceMap;

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

        // Get a reference to the MapView in your layout file
        mMapView = findViewById(R.id.mapView);
        wenceMap = new ArcGISMap(Basemap.Type.OPEN_STREET_MAP,0.47867,37.803972, 7 );
        mMapView.setMap(wenceMap);
    }

    @Override
    protected void onPause()
    {
        mMapView.pause();
        super.onPause();
    }

    @Override
    protected void onResume()
    {
        super.onResume();
        mMapView.resume();
    }

    @Override
    protected void onDestroy()
    {
        super.onDestroy();
        mMapView.dispose();
    }
}

当前Gradle配置 #

手动引入ArcGIS SDK的配置：

implementation files('libs/arcgis-runtime-sdk-java-200.0.0/libs/arcgis-android-100.15.1.aar')

其他依赖：

implementation 'androidx.appcompat:appcompat:1.6.1'
implementation 'com.google.android.material:material:1.8.0'
implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
implementation 'androidx.navigation:navigation-fragment:2.5.3'
implementation 'androidx.navigation:navigation-ui:2.5.3'
testImplementation 'junit:junit:4.13.2'
implementation 'org.apache.httpcomponents:httpcore:4.4.14'
//implementation "com.esri.arcgisruntime:arcgis-java:100.15.1"
runtimeOnly "org.slf4j:slf4j-nop:1.7.32"
implementation files('libs/volley-1.2.1.aar')

解决方案 #

1. 补充正确的Apache HttpClient 5依赖 #

报错缺失的org.apache.hc.core5.http.message.BasicNameValuePair属于Apache HttpClient 5.x版本，当前引入的httpcore:4.4.14是4.x版本，两者不兼容。需添加5.x系列的依赖：

implementation 'org.apache.httpcomponents.client5:httpclient5:5.2.1'
implementation 'org.apache.httpcomponents.core5:httpcore5:5.2.1'

2. 清理并重建项目 #

添加依赖后执行以下操作：

• 点击Android Studio的Build -> Clean Project
• 再点击Build -> Rebuild Project
• 重启Android Studio后重新运行应用

3. 排查Dex分包问题（可选） #

如果仍出现类找不到的情况，可能是Dex分包导致的，在build.gradle(Module)中启用Dex分包：

android {
    defaultConfig {
        multiDexEnabled true
    }
}

同时添加MultiDex依赖：

implementation 'androidx.multidex:multidex:2.0.1'

并让MainActivity继承MultiDexAppCompatActivity，或在自定义Application类中初始化MultiDex。
