Android Studio can't find my JSON file

Question

I created a raw Android resource directory in res and added cars.json to it. It shows up on my package explorer. When I try to call

File file = new File("raw/cars.json")

I get a FileNotFoundException. I've tried using simply cars.json and even the entire path to the file but I get the same results.

Any suggestions?

have toy tried using `File file = new File("android.resource://"+getPackageName()+"/raw/equipment.json");` — V-rund Puro-hit, Sep 29 '16 at 13:50
If your file is titled cars.json why are you loading equipment.json? Is that a typo? — Ben, Sep 29 '16 at 13:50

To get a resource from the raw directory call getResources().openRawResource(resourceName).

This will give you a InputStream

You can use this function directly:

private String getJsonStringFromRaw(filenmae)
{
    String jsonString = null; 
    try { 
        InputStream inputStream= getAssets().open(filename); 
        int size = inputStream.available(); 
        byte[] buffer= new byte[size]; 
        inputStream.read(buffer); 
        inputStream.close(); 
        jsonString = new String(buffer, "UTF-8"); } 
    catch (IOException e) 
    { 
        e.printStackTrace(); 
        return null; 
    } 
    return jsonString; 
}

You can access json data by iterating through the json object below. JSONObject obj = new JSONObject(getJsonStringFronRaw("cars.json"))

Retrieving resource from the raw directory can be achieved with openRawResources a sub class of getResources, this takes in a resource id (your json file) and returns a InputStream.

InputStream myInput=getResources().openRawResource(R.raw.your_json);

If you need more info, here is the google documention
