Question

使用产品：imobile 10.2 操作系统：win10 x64 华为OS（相当于安卓10）
数据类型： 文件型
问题详细描述：跟着3、SuperMap iMobile for Android快速入门-Android教程-腾讯课堂 (qq.com)网页的教程做，遇到java.lang.NullPointerException错误。

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        //指定路径，新建文件夹
        Environment.setLicensePath("/sdcard/SuperMap/License/");
        Environment.setWebCacheDirectory("/sdcard/SuperMap/WebCache/");
        Environment.setTemporaryPath("/sdcard/SuperMap/temp/");
//        Environment.getLicenseStatus();
        //初始化
        Environment.initialization(this);
        setContentView(R.layout.activity_main);

        //打开工作空间
        Workspace world = new Workspace();
        WorkspaceConnectionInfo info = new WorkspaceConnectionInfo();
        info.setServer("/sdcard/SuperMap/GeometryInfo/World.smwu");
        info.setType(WorkspaceType.SMWU);
        world.open(info);

        //关联地图显示控件和工作空间
        MapControl mapControl = findViewById(R.id.mapControl);
        mapControl.getMap().setWorkspace(world);

        //打开第一幅地图
        String mapName = world.getMaps().get(0);
        mapControl.getMap().open(mapName);
        mapControl.getMap().refresh();

    }

问题重现步骤： 1.在onCreate函数里打断点，然后调试

2.Environment.initialization(this) 初始化报错

Answer 1

您好，请问您是否有做以下操作

1.app申请读取等相关，

2.测试机上是否权限打开，

3.如果上述两步还是不行，在debug模式下查看是否读取到许可路径

4.更换许可，重新申请试用许可

5.如果都不行，请下载Supermap Itablet查看是否可用

你好，我在debug模式下如何查看是否读取到许可路径？用什么函数，添加到哪里？

---

如果是以下代码，调试的时候会出现Source code does not match the bytecode这一句，初始化失败，不会运行get函数。

        Environment.initialization(this);
        Environment.getLicenseStatus();

如果调换这两句代码，那么会报错

Caused by: java.lang.IllegalStateException: Please call com.supermap.data.Environment.initialization() firstly

也就是需要先初始化。

Answer 2

可能是库没有导入，需要在app的build.gradle文件下加上

sourceSets {
    main{
        jniLibs.srcDirs=['libs']
    }
}

已经添加了，谢谢你
