您好，您那边设备路径里面有/SuperMap/license路径吗？是否对设备开启了动态权限，设置的targetsdkversion小于或者等于28

---

您好，我用的Android studio里面的模拟机，需要怎么配置/SuperMap/license路径呢 我看帮助文档里面没有写 我的targetsdkversion是31

---

模拟器也是需要使用许可的，需要在模拟器对应位置创建文件夹并拷贝许可进去。targetsdkversion建议设置为小于等于28，因为Android10以上使用的是沙盒存储机制，一个app对应一个存储目录

---

请问模拟机的路径是下载时候的路径吗 然后创建一个SuperMape文件夹 把license拷贝进去吗 targetsdkversion设置为21可以吗

---

你可以理解为模拟器就是一个手机，你在Android studio里面去设置相关路径，具体可以百度搜索一下。设置为21也是可以的，

---

好的 十分感谢您!

您好，我按照您说的改完了以后 又出现了新的问题 

现在为Caused by: java.lang.NullPointerException: Attempt to get length of null array
        at com.supermap.data.Environment.checkAndLoadLibrary64(Environment.java:1736)
        at com.supermap.data.Environment.initialization(Environment.java:584)
        at com.example.supermapimobile3d.MainActivity.onCreate(MainActivity.java:24)

  at com.example.supermapimobile3d.MainActivity.onCreate(MainActivity.java:24)这一行报错

Environment.initialization(this);这一行代码的问题

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

        String sdcard= android.os.Environment.getExternalStorageDirectory().getAbsolutePath().toString();
        Environment.setLicensePath(sdcard+"/SuperMap/license/");
        Environment.initialization(this);

        setContentView(R.layout.activity_main);

        Button btnOpen = (Button)findViewById(R.id.btn_open);
        btnOpen.setOnClickListener(new OnClickListener()

---

这个是因为ndk的原因，需要在build.grandle文件里面设置ndk

---

好的 我检查一下

---

我写了

ndk {
    abiFilters 'armeabi-v7a','x86','x86-64'
}以后

又报错了

Installation did not succeed.
The application could not be installed: INSTALL_FAILED_NO_MATCHING_ABIS

List of apks:
[0] 'D:\SuperMapiMobile3D\app\build\outputs\apk\debug\app-debug.apk'
Installation failed due to: 'INSTALL_FAILED_NO_MATCHING_ABIS: Failed to extract native libraries, res=-113'
这是错误原因

写了ndk后还是有错误 然后百度写了

splits {
    abi {
        enable true
        reset()
        include 'x86', 'armeabi-v7a', 'x86-64'
        universalApk true
    }

然后又报错

at com.example.supermapimobile3d.MainActivity.onCreate(MainActivity.java:24)还是这行报错

---

你那边看下libs里面的so文件的文件夹名称是啥？ndk里面就设置这个文件夹名称

---

是armeabi-v7a  那还需要x86吗

---

不需要了，只设置armeabi-v7a 就可以
