I am trying to pass an arraylist of objects between two activities, but my app crushes at the second activity. Can someone help me solve this problem...
Here is my code from my first activity:
Intent i = new Intent();
Bundle b = new Bundle();
b.putParcelableArrayList("songs",(ArrayList<? extends Parcelable>) albumsArray.get(position).getSongs());
Log.v("--", "OK");
i.putExtras(b);
i.setClass(LatestAlbums.this, AlbumDetails.class);
startActivity(i);
And code from the second activity:
songs=new ArrayList<Songs>();
Bundle b = this.getIntent().getExtras();
if(b!=null)
songs = b.getParcelable("songs");
Log.v("--", songs.size()+"");
And my logcat output:

You try the below
intent.putParcelableArrayListExtra("key", ArrayList<T extends Parcelable> list);
startActivity(intent);
Retrieve it
getIntent().getParcelableArrayListExtra("key");
Pass arraylist of user defined objects to Intent android. Check the answer by Sajmon
According to the comments made by Sajmon, Song
class has to implement
Parcelable
