Issues uploading images

Question

I have successfully been able to store user entered information into parse, but I have been having difficulty storing images into to parse, to be able to retrieve at a later date.

To clarify this, below is the code I have used for my profile creation activity, an activity that is prompted after the user has signing using social media and responds to a series of questions like age, preferred name, and where those information are later updated in the parse database and added to the current user.

Also in the activity, the user is already able to upload a picture from their device, my issue now resolves around taking that uploaded picture and storing it on parse, and associating the image with the current user who has signing using their social media account - the social media integration is done through parse.

I have looked into the following guide, but is still greatly confused.https://www.parse.com/docs/android_guide#files

Now I have tried to accomplish this, and have left my comments in the code below.

Any assistance would be greatly appreciated. Thanks in advance.

public class ProfileCreation extends Activity {

    private static final int RESULT_LOAD_IMAGE = 1;
    FrameLayout layout;
    Button save;
    protected EditText mName;
    protected EditText mAge;

        v.requestFocus();

        Parse.initialize(this, "ID", "ID");

        mName = (EditText)findViewById(R.id.etxtname);
        mAge = (EditText)findViewById(R.id.etxtage);
        mHeadline = (EditText)findViewById(R.id.etxtheadline);
        mprofilePicture = (ImageView)findViewById(R.id.profilePicturePreview);

        mConfirm = (Button)findViewById(R.id.btnConfirm);
        mConfirm.setOnClickListener(new View.OnClickListener() {

Answer 1

You need to wait for the file to finish saving before you add it to the user.

Try adding a completion block to your file.saveInBackground() call, and moving all the currentUser manipulation into that completion block.
