【报Bug】系统公共目的下的文件不支持移动和拷贝到沙盒目录？

示例代码：

        moveCopyFileToDst: function(files, method, succCallback, errCallback) {  
            var _this = this,  
                result = [];  

            function copyfile(fileEntry, dstEntry, fileName, callback) {  
                fileEntry.copyTo(dstEntry, fileName, function(entry) {  
                    callback(entry)  
                }, function(e) {  
                    console.log(e.message + ' 有些文件路径不存在或无法复制')  
                    errCallback(e.message)  
                })  
            }  

            function movefile(fileEntry, dstEntry, fileName, callback) {  
                console.log('movefile moveTo fileEntry.fullPath', fileEntry.fullPath)

                console.log('movefile moveTo dstEntry.fullPath', dstEntry.fullPath)  
                console.log('movefile moveTo fileName', fileName)

                    plus.nativeUI.closeWaiting()  
                }, config)

操作步骤：

manifest.json targetSdkVersion 值为 30
1、pick 选择图片。
2、勾选最下面的“原图”。
3、选图片。
4、判断 _doc/images 下是否有该文件。如果不存在就移动到 _doc/images 下，存在就重新启个名字再移动到 _doc/images 下。

预期结果：

移动或复制成功

实际结果：

targetSdkVersion设置>=29后在Android10+系统设备不支持当前路径。请更改为应用运行路径！具体请看:https://ask.dcloud.net.cn/article/36199
