Parceable encountered IOException writing serializable object

Question

I am getting this error :

                FATAL EXCEPTION: main

When running this :

holder.butArea.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                Intent myIntent = new Intent(v.getContext(), game.LevelActivity.class);
                myIntent.putExtra("switchlevel", LevelSwitchCase.getLevel(currentLevel, (pos+1),mContext));
                myIntent.putExtra("level",currentLevel);
                myIntent.putExtra("area", (pos+1));

                v.getContext().startActivity(myIntent);

            }
        });

game.level is implementing serializable and getting the error when launching the intent (v.getContext().startActivity(myIntent);)

level and area are just integers and switchlevel is a level I am getting (implements Serializable)

Solution 1

Context is not Serializable. To fix this error I declared Context like this(variable doesnt serialize) :

  public transient Context mContext;

or you can implement Parceable.

Solution 2

If your level class has non primitive members they should also implement serializable.

Normally every object I use there is implementing Serializable , could it be an other problem?
