Issues traversing through directory hierarchy with Android Storage Access Framework / DocumentProvider using MTP
I am using your code to go in sub folders with adding lines: Uri childrenUri; try { //for childs and sub child dirs childrenUri = DocumentsContract.buildChildDocumentsUriUsingTree(uri, DocumentsContract.getDocumentId(uri)); } catch (Exception e) { // for parent dir childrenUri = DocumentsContract.buildChildDocumentsUriUsingTree(uri, DocumentsContract.getTreeDocumentId(uri)); }
