Question

I am trying to restore an array of Objects from a savedInstanceState. I added each one to the Bundle individually here: (rhythm is the array of Objects)

@Override
public void onSaveInstanceState(Bundle outState){
    outState.putInt("numParts",rhythm.length);
    for(int index = 0;index<rhythm.length;++index){
        outState.putSerializable(""+index,rhythm[index].beat);
    }
    super.onSaveInstanceState(outState);
}

When the onRestoreInstanceState() method is called, I try to assign my rhythm array with the Objects from the Instance State here: (it isn’t null)

@Override 
public void onRestoreInstanceState(Bundle savedInstanceState){
    rhythm = new Part[savedInstanceState.getInt("numParts")];
    for(int index = 0; index<rhythm.length;++index){
         Object middleMan =savedInstanceState.getSerializable(""+index);
         if(middleMan==null){
             System.out.println("It's null...");
         }
    rhythm[index]=(Part) middleMan;
    }
}

It throws a ClassCastException when I parse to a Part every time. Part implements Serializable. Why is it not allowing me to parse? Will I need to do custom serialization?
Please help!

Okay I just did it as the whole array and it worked… I don’t really know why, but it did. Thanks for giving me the idea to just pass the whole array. @Error 454
