Parker Yuan Posted September 16, 2021 Author Share Posted September 16, 2021 wave Native SDK调用PermissionManager requestPermissions,获取文件读写权限，未显示授权弹窗。直接调用Activity requestPermissions,出现弹窗授权确认后，读写文件依然失败，提示java.io.FileNotFoundException: /sdcard/test_log.txt: open failed: EACCES (Permission denied) Link to comment Share on other sites More sharing options...
