When I choose image from gallery, application is crashed - Android

Question

When I choose some images from gallery, application is crashed. I guess I loose activity. Because after choose image, line 77 :mSchoolNumber nullpointer exception is given in InitialiseFields() function. As I researhed, its problem is memory. But I cannot solve it.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_user_edit_profile);
    initializeFields();
    initializeListeners();
}

public void initializeFields(){

    mSchoolNumber = (EditText) findViewById(R.id.editSchoolNumber);
    mUserName = (EditText) findViewById(R.id.editUserName);
    mPassword = (EditText) findViewById(R.id.editPassword);
    saveInfoButton = (Button)findViewById(R.id.saveInfoButton);
    editProfileImageProgresBar = (DonutProgress)findViewById(R.id.editProfileImageProgresBar);
    editProfileImageView = (ImageView)findViewById(R.id.editProfileImageView);
    imageLoader = ConfigFile.getImageLoader(this);
    mainActivityIntent = new Intent(this, MainActivity.class);

    mSchoolNumber.setText(UniPromClient.getSchoolNumber().toString());
    mUserName.setText(UniPromClient.getUserName().toString());
    mPassword.setText(UniPromClient.getPassword().toString());

    //showProfileImageOnServer();
}

class ImagePickListener implements OnClickListener {
    @Override
    public void onClick(View v) {

        try{
            Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);//ACTION_GET_CONTENT
            intent.setType("image/*");
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
                intent.putExtra(Intent.EXTRA_LOCAL_ONLY, true);
            }
            startActivityForResult(Intent.createChooser(intent, "Bir Fotoğraf Seçin"), IMAGE_PICK);

        }catch(Exception e){

        }
    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == IMAGE_PICK && resultCode == RESULT_OK && null != data && data.getData() != null) {
        if (resultCode == Activity.RESULT_OK) {
            switch (requestCode) {
                case IMAGE_PICK:
                    this.imageFromGallery(resultCode, data);
                    break;
                default:
                    break;
            }
        }
    }
}

private void imageFromGallery(int resultCode, Intent data) {

    try{

        pd.show();
        Uri selectedImage = data.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);
        File file = new File(filePath);
        cursor.close();
        //sendProfileImage(file,filePath);//Bunu kaldırıp dene bir de    

    }catch(Exception e){

    }

}

What is this line mainActivityIntent = new Intent(this, MainActivity.class); in your initializeFields() doing ? — Rakshit Nawani, May 20 '16 at 18:58
@fuat : remove the line mainActivityIntent = new Intent(this, MainActivity.class); and then run the code. — Rakshit Nawani, May 20 '16 at 19:03
@RakshitNawani I tried. It doesn't work. I is not important sense — fuat, May 20 '16 at 19:09
