file path return null always in lollipop android

Question

this is my code when i'm getting image from internal storage (gallery). In lollipop file path return always null.

if (requestCode == PICK_IMAGE)  {
        if(resultCode == RESULT_OK){
            //image successfully picked
            // launching upload activity
            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };
            Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);
            cursor.moveToFirst();
            columnindex = cursor.getColumnIndex(MediaStore.Images.Media.DATA);
            file_path = cursor.getString(columnindex);
            Log.d(getClass().getName(), "file_path"+file_path);
            fileUri = Uri.parse("file://" + file_path);
            cursor.close();
            launchUploadActivity(true, PICK_IMAGE);
        }else if (resultCode == RESULT_CANCELED) {
            // user cancelled recording
            Toast.makeText(getApplicationContext(),"User cancelled image  selection", Toast.LENGTH_SHORT).show();
        } else {
            // failed to record video
            Toast.makeText(getApplicationContext(),"Sorry! failed to pick image", Toast.LENGTH_SHORT).show();
        }

Thanx all,I found the solution.

    Uri selectedImage = data.getData();
            String wholeID = DocumentsContract.getDocumentId(selectedImage);

            // Split at colon, use second item in the array
            String 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();
            setImageFromIntent(filePath);

Add permission to your manifest -

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

you have to define read permission, before read any content.

EDITED

Update your code -

        Uri selectedImage = data.getData();
        String[] filePathColumn = { MediaStore.Images.Media.DATA };
        Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);

        columnindex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        file_path = cursor.getString(columnindex);
        Log.d(getClass().getName(), "file_path"+file_path);
        fileUri = Uri.parse("file://" + file_path);
        cursor.close();
        launchUploadActivity(true, PICK_IMAGE);

So here if any exception in getting data from cursor then it throws exception.

Lollipop decided to take another course with getting files from the system. (Some say it is from KitKat, but I haven't encountered it yet on KitKat). The code below is to get the filepath on lollipop

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT && isMediaDocument(uri))
    {
        final String docId = DocumentsContract.getDocumentId(uri);
        final String[] split = docId.split(":");
        final String type = split[0];

        Uri contentUri = null;
        if ("image".equals(type)) 
        {
            contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
        }

        final String selection = "_id=?";
        final String[] selectionArgs = new String[] {
                split[1]
        };

        String filePath = getDataColumn(context, contentUri, selection, selectionArgs);
    }

isMediaDocument:

public static boolean isMediaDocument(Uri uri)
{
    return "com.android.providers.media.documents".equals(uri.getAuthority());
}

getDataColumn:

private static String getDataColumn(Context context, Uri uri, String selection, String[] selectionArgs)
{
    Cursor cursor = null;
    final String column = "_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);
        }
    } finally {
        if (cursor != null)
            cursor.close();
    }
    return null;
}

If you still have problems, this is the full answer that checks for images, audio, video, files, etc.

public void String(Uri file_uri){
    String path = null;
    Cursor returnCursor = getContext().getContentResolver().query(file_uri, null, 
                             null, null, null);
    if (returnCursor != null && returnCursor.moveToFirst()) {
        //to get file name 
        int nameIndex = 
        returnCursor.getColumnIndex(OpenableColumns.DISPLAY_NAME);
        //string filename will get a filename which you have choosen
        String fileName = returnCursor.getString(nameIndex); 
        //to get full path of image
        path = returnCursor.getString(returnCursor.getColumnIndex(MediaStore.MediaColumns.DATA));
    }
    return path;
