Android: java.lang.OutOfMemoryError

I am trying to open a huge image from the web, on the second item when i try to load the image... i get the below error. 

@Override
protected void onPostExecute(String result) {
    progress.dismiss();

    try {
        JSONObject documentRoot = new JSONObject(result);
        String data = documentRoot.getString("Data");
        if (data.length() < 10) {
            Toast.makeText(Activity.this, "This is not a valid document", Toast.LENGTH_SHORT).show();
            finish();
        } else
            openPDF(data);
    } catch (Exception e) {
        Toast.makeText(Activity.this, "Document could not be opened", Toast.LENGTH_SHORT).show();
        finish();
    }
}

I am getting error in JSONObject documentRoot = new JSONObject(result); this line.

It sounds like the data is just too large to hold in a String. How are you representing this PDF that it can be loaded from a String anyway? maybe it's a better idea to provide a URL in the JSON, and then you can use generic downloader code to get the PDF, without storing too much data in memory at a time.
