Parceable encountered IOException writing serializable object

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)

For those who use context or other non-serializable objects inside an interface. Simply pass it as a parameter to a method, for instance:

public interface OnActionInterface {
    void onPositiveButtonClicked(Activity activity);
    void onNegativeButtonClicked(Activity activity);
}

Then create a standalone class like:

public class SomeClass implements OnActionInterface, Serializable {
    private String action;

    public SomeClass(String action) {
        this.action = action;
    }

    @Override
    public void onPositiveButtonClicked(Activity activity) {
        Intent intent = new Intent(action);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        activity.startActivity(intent);
    }

    @Override
    public void onNegativeButtonClicked(Activity activity) {
        activity.finish();
    }
}

After that you can use objects of this class inside intents.

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.

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