Get real path from URI, Android KitKat new storage access framework [duplicate]
This will get the file path from the MediaProvider, DownloadsProvider, and ExternalStorageProvider, while falling back to the unofficial ContentProvider method you mention.

These are taken from my open source library, aFileChooser.
Note: This answer addresses part of the problem. For a complete solution (in the form of a library), look at Paul Burke's answer.
You could use the URI to obtain document id
, and then query either MediaStore.Images.Media.EXTERNAL_CONTENT_URI
or MediaStore.Images.Media.INTERNAL_CONTENT_URI
(depending on the SD card situation).
To get document id:
// Will return "image:x*"String wholeID = DocumentsContract.getDocumentId(uriThatYouCurrentlyHave);// Split at colon, use second item in the arrayString id = wholeID.split(":")[1];String[] column = { MediaStore.Images.Media.DATA }; // where id is equal to String sel = MediaStore.Images.Media._ID + "=?";Cursor cursor = getContentResolver(). query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, column, sel, new String[]{ id }, null);String filePath = "";int columnIndex = cursor.getColumnIndex(column[0]);if (cursor.moveToFirst()) { filePath = cursor.getString(columnIndex);} cursor.close();
Reference: I'm not able to find the post that this solution is taken from. I wanted to ask the original poster to contribute here. Will look some more tonight.
the answer below is written by https://stackoverflow.com/users/3082682/cvizv on a page which does not exist anymore, since he has not enough rep to answer a question, I am posting it. No credits by me.
public String getImagePath(Uri uri){ Cursor cursor = getContentResolver().query(uri, null, null, null, null); cursor.moveToFirst(); String document_id = cursor.getString(0); document_id = document_id.substring(document_id.lastIndexOf(":")+1); cursor.close(); cursor = getContentResolver().query( android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, null, MediaStore.Images.Media._ID + " = ? ", new String[]{document_id}, null); cursor.moveToFirst(); String path = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA)); cursor.close(); return path;}
Edit: There is a flow on the code; if device has more than one external storage (external sdcard, external usb etc.), above the code won't work non primary storages.
