    public String getRealPathFromURI(Context context, Uri contentUri) {
    Log.d("imin", "onClick: in image conversion");

    Cursor cursor = null;
    try {
        String[] proj = {MediaStore.Images.Media.DATA};
        cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        Log.d("imin", "onClick: in image conversion try");

        return cursor.getString(column_index);
    } finally {
        Log.d("imin", "onClick: in image conversion finally");

        if (cursor != null) {
            cursor.close();
        }
    }
}
