Referencing a file in android studio

Question

I'm writting some code that uses a serialized file. The file is called alcala.ser and is in utils, a subfolder of java. The class calling the file is in the same folder. Here's the code:

InputStream file = new FileInputStream("/alcala.ser");

I also tried:

InputStream file = new FileInputStream("alcala.ser");

In both cases, I get

java.io.FileNotFoundException: /alcala.ser: open failed: ENOENT (No such file or directory)

How should I reference the file?

Thanks in advance.

`/alcala.ser` would be the root of the device... I doubt your file would exist there anyways because write access is not allowed — OneCricketeer, Mar 01 '16 at 17:01
You should [make an `assets` folder](http://stackoverflow.com/a/27673773/2308683) to store your files. — OneCricketeer, Mar 01 '16 at 17:03

The file is called alcala.ser and is in utils, a subfolder of java.

Move the file out of there and into assets/. Then, use AssetManager to open() an InputStream on the asset.

But I can't reference a 'non-static' method from a 'static' context... any ideas? – Daniel Hurtado Ramirez Mar 01 '16 at 17:57

@DanielHurtadoRamirez: If the method in question is `open()`, you get an `AssetManager` instance by calling `getAssets()` on a `Context`, such as an `Activity` or `Service`. – CommonsWare Mar 01 '16 at 17:59

Check External and Internal Storage option in http://developer.android.com/guide/topics/data/data-storage.html. Depending on how do you want to handle privacy you have to chose one or the other.
