作者自己用Uri.getPath了，这个path根本就不能用，只能download代码自己动刀

解决方案是什么？

[meablelee2013]

Uri.getPath确实不能用，暂时将Uri转成了String用的

`

public static String getDataColumn(Context context, Uri uri, String selection, String[] selectionArgs) { Cursor cursor = null; final String column = MediaStore.Images.Media.DATA; final String[] projection = {column}; try { cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs, null); if (cursor != null && cursor.moveToFirst()) { final int column_index = cursor.getColumnIndexOrThrow(column); return cursor.getString(column_index); } } catch (Exception ex) { ex.printStackTrace(); } finally { if (cursor != null) { cursor.close(); } } return null; } `
