Question

按照帮助文档->开发指南->android studio->开发二维移动GIS程序，编写第一个程序。安装到手机以后，程序打开，地图不显示。
核心代码如下：
 

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        String rootPath = android.os.Environment.getExternalStorageDirectory().getAbsolutePath();
        Environment.setTemporaryPath(rootPath + "/SuperMap/temp");
        Environment.setLicensePath(rootPath + "/SuperMap/license");
        Environment.setWebCacheDirectory(rootPath + "/SuperMap/webCache");
        Environment.setFontsPath(rootPath + "/SuperMap/fonts");
        Environment.initialization(this);

        setContentView(R.layout.activity_main);

        Workspace mWorkspace = new Workspace();
        WorkspaceConnectionInfo info = new WorkspaceConnectionInfo();
        info.setServer(rootPath + "/SuperMap/GeometryInfo/World.smwu");
        info.setType(WorkspaceType.SMWU);
        mWorkspace.open(info);

        MapView mapView = findViewById(R.id.Map_view);
        mapControl = mapView.getMapControl();
        mapControl.getMap().setWorkspace(mWorkspace);

        String mapName = mWorkspace.getMaps().get(1);
        mapControl.getMap().open(mapName);
        ZoomControls mZoom = findViewById(R.id.zoomControl);
        mZoom.setIsZoomInEnabled(true);
        mZoom.setIsZoomOutEnabled(true);

        mZoom.setOnZoomInClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                mapControl.getMap().zoom(2);
                mapControl.getMap().refresh();
            }
        });

        mZoom.setOnZoomOutClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                mapControl.getMap().zoom(0.5);
                mapControl.getMap().refresh();
            }
        });

        mapControl.getMap().refresh();
        setContentView(R.layout.activity_main);
    }

配置如下：

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

            android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>

                    android:configChanges="keyboardHidden|orientation|screenSize"/>

                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>
    <supports-screens
        android:anyDensity="true"
        android:largeScreens="true"
        android:normalScreens="true"
        android:smallScreens="true"
        tools:ignore="ManifestOrder"/>
</manifest>
