Question

运行到这一步闪退， 权限也全部允许了

然后日志

我的文件路径都没错，许可也在有效期

Answer 1

您好，在Android6.0版本后需要设置动态权限，您那边有对手机的读写设置权限吗？可以调试一下看是否能获取设备下的文件

权限全部允许了

您那边能否提供一下详细的报错信息，然后打印输出一下能否获取设备中的文件

结果：

E/11111: /storage/emulated/0/SuperMap/license/
E/22222: /storage/emulated/0/SuperMap/temp/
E/33333: /storage/emulated/0/SuperMap/WebCatch

错误：

是什么原因导致的？

---

您这个报错是由于我们目前提供的包暂时不支持64位库，需要您在在grandle中设置ndk。

ndk{
    abiFilters 'armeabi-v7a','armeabi'
}

---

是在model里的grandle还是在外面的grandle，具体哪个位置？

---

model里面的grandle，写在defaultConfig节点下，可以参考一下这篇博客:;https://blog.csdn.net/yao_94/article/details/79151804

---

加了你给的这段代码还是保同样的错，

---

设置ndk的时候只需要设置你所加的so库的文件夹名称，如armeabi-v7a

好的，成功了，谢谢
