Include local .json file in Eclipse Android project

I have a local .json file. I don't want it to be on a server, I just want it to be included in my app. I tried to paste it directly into Eclipse in my project, but I got a FileNotFoundException, I also tried to paste it in the workspace folder in Windows Explorer/Finder and got the same exception. Where should I put it?

Thanks!

Copy Asset to Local Storage

I had a very similar need. I had a label template file that I needed to provide a Bluetooth printer configuration so I included it in my assets directory and copied it to the internal storage for later use: 

private static final String LABEL_TEMPLATE_FILE_NAME = "RJ_4030_4x3_labels.bin";

InputStream inputStreamOfLabelTemplate = getAssets().open( LABEL_TEMPLATE_ASSET_PATH );

labelTemplateFile = new File( getFilesDir() + LABEL_TEMPLATE_FILE_NAME );

copyInputStreamToFile( inputStreamOfLabelTemplate, labelTemplateFile );

printer.setCustomPaper( labelTemplateFile.getAbsolutePath() );

copyInputStreamToFile Function

// Copy an InputStream to a File.
//
private void copyInputStreamToFile(InputStream in, File file) {
    try {
        OutputStream out = new FileOutputStream(file);
        byte[] buf = new byte[1024];
        int len;
        while((len=in.read(buf))>0){
            out.write(buf,0,len);
        }
        out.close();
        in.close();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Put the json file in assets folder, I have used this method like this

public static String jsonToStringFromAssetFolder(String fileName,Context context) throws IOException {
        AssetManager manager = context.getAssets();
        InputStream file = manager.open(fileName);

        byte[] data = new byte[file.available()];
        file.read(data);
        file.close();
        return new String(data);
    }

While parsing we can use the method like:

String jsondata= jsonToStringFromAssetFolder(your_filename, your_context);
jsonFileToJavaObjectsParsing(jsondata);  // json data to java objects implementation

You should put the file either in the /assets or /res/raw directory of your Android project. From there, you can retrieve it with either: Context.getResources().openRawResource(R.raw.filename) or Context.getResources().getAssets().open("filename").

Put the file in the assets folder. You can use the AssetManager open(String fileName) to read the file.

Under /assets in your project folder. If you don't have one, make it.
