Android crashes after signaturepad

Question

I am building an android app with two activities. The first activity has 50 Fields ( textinputedittext, radiobuttons and toggle buttons). I am saving the data of those fields in a json file and then I navigate to my second activity where the user cab draw its signature on this signature pad:

https://github.com/gcacace/android-signaturepad

I save the singature on a jpg image and return back to the first activity. So far so good.

Now when I try to take a second signature from my second activity, my app crashes when I return back again to my first activity, with the following stack trace:

I can see that parcelable is to large but I only pass a string ( a filename ) from one activity to other. I can not understand what is this big parcel that crashes my application.

Any help is appreciated.

You must be passing a long string with Bundle like this and you have to clear the Bundle where you are receiving data. You can use whatever way thinks good.

1.Method:

Bundle bundle = new Bundle();
bundle.putString("This is just for testing purpose add your data key", "your string");

To clear bundle object on Fragment

  @Override 
    public void onViewCreated(View view, Bundle savedInstanceState) 
    {
        String recStr= bundle.get("This is just for testing purpose add your data key");       
        bundle.clear();   
    }

2.Method

@Override
protected void onSaveInstanceState(Bundle oldInstanceState) 
{
    super.onSaveInstanceState(oldInstanceState);
    oldInstanceState.clear();
}

Try like this as per your requiremnts.
