Question

Here is the thread that I read about making a stack of resources from AssetManager in Android.

What does it mean to “creating a stack of resources from AssetManager?” Do I have to use:

Stack stack = new Stack();
stack.push(this.getAssets());

Or something? If anyone can give hints, I appreciate it. If the question is not specific enough, please post in the comments about it, and I’ll improve the question. Thanks in advance.

A Stack is just a collection of Objects, the same as an array, ArrayList, Collection, etc.

The benefit of using a Stack is that you can simply push(Object o) objects in to the Stack to add them to the collection, and pop() objects off the Stack when you want to get them back. A Stack can grow to any size.

You would probably need to do something like this…

Stack stack = new Stack();
AssetManager assets = this.getAssets();
String[] assetLocations = assets.list();

for (int i=0;i<assetLocations.length;i++){
    byte[] asset = loadAssetFromStream(assetLocations[i]); // you need to write this
    stack.push(asset);
}

AssetManager has an open() method for reading the assets – you’ll probably need to read each asset into memory (like a byte[] array or an actual Object) and then push each object into the stack.
