Image file uploading using OKHTTP

Yo!

Glad you're using OkHttp. AsyncTask sucks. At my current and last workplace, we talked about how we disliked AsyncTask with burning passion.

I found this bunch of OkHttp recipes for you to check out. The one you're looking for is "posting a file":

You're going to need to start using the Android Filesystem in order to locate the file too.

Read up on these API's http://developer.android.com/reference/java/io/File.html http://developer.android.com/reference/android/os/FileObserver.html <-- Important if you're using the camera!

I have an example I wrote for a recent job interview you can check out here. It was a code challenge for a company here in Los Angeles. Check out MainActivity.java https://github.com/MrBenJ/WritingFilesAndroid/blob/master/app/src/main/java/com/prismmobile/cyberdustcc/MainActivity.java

Look at this particular block of code to see how files are retrieved from the system:

FileInputStream fileInputStream;

        try {
            fileInputStream = openFileInput("list");
            ObjectInputStream objectInputStream = new ObjectInputStream(fileInputStream);
            ArrayList<String> noteList = (ArrayList<String>) objectInputStream.readObject();
            objectInputStream.close();
        }
        catch(Exception e) {
            e.printStackTrace();
        }

Here's a block of code that writes to a file

@Override
    public void onPause() {
        super.onPause();

        try {
            FileOutputStream fileOutputStream = this.openFileOutput("list", Context.MODE_PRIVATE);
            ObjectOutputStream oos = new ObjectOutputStream(fileOutputStream);
            oos.writeObject(noteList);
            oos.close();
        }
        catch(Exception e) {
            e.printStackTrace();
        }

I know this isn't particularly the answer you're looking for, but hopefully it sheds some insight on what you're trying to do.

Good luck!
