Android preference startActivityForResult always return data null

Question

I have an issue with the image picker from preference activity. I created a preference and when click on it, application will go to image picker screen. But when I pick an image there is no data is retrieved.

Here is my code which call to startActivityForResult

Preference chooseImageFromGal = (Preference) findPreference("pref_key_background_device");
    chooseImageFromGal.setOnPreferenceClickListener(new OnPreferenceClickListener() {

        @Override
        public boolean onPreferenceClick(Preference preference) {
            // TODO Auto-generated method stub
            Intent intent = new Intent();
            intent.setType("image/*");
            intent.setAction(Intent.ACTION_GET_CONTENT);
            SettingActivity.this.startActivityForResult(Intent.createChooser( intent, "Select Picture"), IMAGE_FROM_DEVICE);
            return true;
        }
    });

Here is my onActivityResultFunction. The imageReturnedIntent is null and resultCode = 0.

protected void onActivityResult(int requestCode, int resultCode, 
           Intent imageReturnedIntent) {
        super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
        if(imageReturnedIntent == null)
            Toast.makeText(SettingActivity.this, "null", Toast.LENGTH_SHORT).show();
        if(requestCode == IMAGE_FROM_DEVICE) {

            if(resultCode == RESULT_OK){  
                Uri selectedImage = imageReturnedIntent.getData();
                String[] filePathColumn = {MediaStore.Images.Media.DATA};

                Cursor cursor = getContentResolver().query(
                                   selectedImage, filePathColumn, null, null, null);
                cursor.moveToFirst();

                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                String filePath = cursor.getString(columnIndex);
                cursor.close();

                Toast.makeText(SettingActivity.this, "ok", Toast.LENGTH_SHORT).show();
            }
        }
    }

And here is the result

I have no idea why function onActivityResult run on this screen. My code work fine on orther project. Please help me to fix this problem. Thanks in advance.

You say "no data is retrieved". Is `onActivityResult()` called? Is the result code `RESULT_OKAY`? Is the selected image `Uri` null? Is the cursor result of the query null or empty? — Bob Snyder, Jul 11 '15 at 19:58
As you see in `onActivityResult` function, if `imageReturnedIntent` is null then the toast is shown. Another problem is `resultCode` = 0 — nchv, Jul 12 '15 at 03:07
Have you seen this [related issue](http://stackoverflow.com/questions/7910840/android-startactivityforresult-immediately-triggering-onactivityresult)? Does your `PreferenceActivity` have `launchMode` in the manifest set to `singleTop` or `singleInstance`? — Bob Snyder, Jul 12 '15 at 03:59
WOW. It is exactly what I want. Thanks you so much to rescue me from a hard week :) — nchv, Jul 12 '15 at 04:09
