Activity force destroyed after choose picture

Question

I have a simple choose image source dialog :

public void toggleImagePicker()
{
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    builder.setTitle("Choose Image Source");
    builder.setItems(new CharSequence[]{"Gallery", "Camera"}, new DialogInterface.OnClickListener()
    {

        @Override
        public void onClick(DialogInterface dialog, int which)
        {
            InputMethodManager inputMethodManager = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
            //                inputMethodManager.hideSoftInputFromWindow(getActivity().getCurrentFocus().getWindowToken(), 0);
            switch (which) {
                case 0:
                    // GET IMAGE FROM THE GALLERY
                    Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
                    intent.setType("image/*");

                    Intent chooser = Intent.createChooser(intent, "Choose a Picture");
                    if (mBackgroundClicked)
                        startActivityForResult(chooser, REQUEST_GALLERY_IMAGE_FOR_BACKGROUND);
                    else
                        startActivityForResult(chooser, REQUEST_GALLERY_IMAGE);
                    break;

                case 1:
                    Intent getCameraImage = new Intent("android.media.action.IMAGE_CAPTURE");

                    File cameraFolder;

                    if (android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED))
                        cameraFolder = new File(android.os.Environment.getExternalStorageDirectory(), ".helper/");
                    else
                        cameraFolder = getActivity().getCacheDir();
                    if (!cameraFolder.exists())
                        cameraFolder.mkdirs();

                    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMdd'T'HHmmss");
                    String timeStamp = dateFormat.format(new Date());
                    String imageFileName = "picture_" + timeStamp + ".jpg";

                    File photo = new File(Environment.getExternalStorageDirectory(), ".helper/" + imageFileName);
                    if (!mBackgroundClicked)
                        mProfilePhotoPath = new String(photo.getAbsolutePath());
                    else
                        mBackgroundPhotoPath = new String(photo.getAbsolutePath());
                    getCameraImage.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photo));
                    //                                initialURI = Uri.fromFile(photo);
                    if (mBackgroundClicked)
                        startActivityForResult(getCameraImage, REQUEST_IMAGE_CAPTURE_FOR_BACKGROUND);
                    else
                        startActivityForResult(getCameraImage, REQUEST_IMAGE_CAPTURE);

                    break;

                default:
                    break;
            }
        }
    });

    builder.show();
}

And i try to pick image, i show the dialog and click on Camera or Gallery. Otherwise my activity is destroyed and recreated.

No exceptions in LogCat.

Single thing what i found in logs :

06-11 14:45:57.700      458-549/? W/InputDispatcher﹕ channel '221e47c0 ******.ProfileExpertActivity (server)' ~ Consumer closed input channel or an error occurred.  events=0x9

Note : pick mechanism implemented in fragment.

Answer 1

If there are no application to handle the action then it will results the NullPointerException before starting the check with resolveActivity to check whether there are any application to handle it or not.

Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
// Verify that the intent will resolve to an activity
if (photoPickerIntent.resolveActivity(getPackageManager()) != null) {
    startActivityForResult(photoPickerIntent, GALLERY_PICKER);    
}
