java.lang.OutOfMemoryError in android Application

Question

        try {       
            Gson gson = new Gson();
            try
            {
                ((ProfileActivity)getActivity()).interactionResult = gson.fromJson(HomeCardString.toString(), InteractionSummaryResult.class);

            }
            catch(Exception e)
            {
                Log.i("myyyy", e.getMessage());
                e.printStackTrace();
            }

        } catch (Throwable t) {
            Log.e("My App", "Could not parse malformed JSON: \"" + responseString + "\"" + t.getMessage());
        }

gson.fromgson..... This line creating exception at Throwable t ..... The data which I have in HomeCardString.toString() is very big. about 1.9MB in a notepad file. I can't reduce the size of that data. What to do with that?

Why can't you reduce the size of the data? 1.9 MB for JSON data is...excessive, to say the least. — Thorn G

You can try setting android:largeHeap="true" for your application in the manifest. Here is the reference:

http://developer.android.com/reference/android/R.styleable.html#AndroidManifestApplication_largeHeap

If this doesn't work, have a look at this post:

JAVA - Best approach to parse huge (extra large) JSON file

Change

        Log.e("My App", "Could not parse malformed JSON: \"" + responseString + "\"" + t.getMessage());

to

        String res = responseString.length() > 160 
            ? responseString.substring(0, 40) + "..." : responseString;
        Log.e("My App", "Could not parse malformed JSON: \"" + res + "\":\n" + t.getMessage());

as logging is not critical.
