How to create a json_template?

I'm creating some code and I saw an example here on this forum, and I have a hard time using geojson.

Whenever it is giving an error in raw because I did not add this json_template

private String getGeoString() throws IOException{
    InputStream is = getResources().openRawResource(R.raw.json_template);
    Writer writer = new StringWriter();
    char[] buffer = new char [1024];
    try{
        Reader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
        int n;
        while ((n= reader.read(buffer)) != -1){
            writer.write(buffer, 0, n);
        }
    }finally {
        is.close();
    }
    String jsonString = writer.toString();
    return jsonString();
}

How can I solve this error?

If you would like to create a json file in your app, you can first create a json_template.json file in your app -> res -> raw folder.

In that file, you can put the entire json response received upon querying.

A useful tool to see the json traversal in the nested response is JSON Pretty Print.

Then you can try:

public static String getGeoString(Context context) throws IOException {

   InputStream is = context.getResources().openRawResource(R.raw.json_template);
   Writer writer = new StringWriter();
   char[] buffer = new char[1024];

   try {
        Reader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
        int n;
        while ((n = reader.read(buffer)) != -1) {
           writer.write(buffer, 0, n);
        }
   } finally {
       is.close();
    }

 // The local variable 'jsonString' can be inlined as below
 return writer.toString(); 
}

It should work. Hope this is helpful.
