I am seeing quite a few error reports from one of my live apps, the caused is this exception:

```

```

From what I've read [here](https://developer.android.com/reference/android/os/TransactionTooLargeException.html), I believe the cause may be down to a too large `Parcelable` I am adding to an `Intent` extras. I am currently passing an Object from one Activity to another, in that Objects `writeToParcel` method I am saving a JSON String which ranges in size from 1000 - 1500 characters in length. Could this be the cause?

Whilst testing the app I sometimes notice the UI lags as though it is low on memory, freezes and then force closes.

Would it be better to pass the Object from one Activity to another using static variables or could this be caused by something else entirely?

Thanks
