QR Code to Google Sheets in Andriod Studio

I have many QR codes ex. Example on imgur, which has peoples' names, numbers, and emails, and I need to scan them. The data comes in something like this: "joe,1234567890,joe#joe.com". I want to write an app that uploads the data to a google sheet and I found a tutorial online from crazycodersclub.com, but when I do the same thing it gives me an error, something like:
Exception: Invalid argument: URL (line 11, file "Code")
Google Script Code
function doGet(e){
var url = encodeUrl("https://docs.google.com/spreadsheets/d/1IEAHcv2n33YO9d7IbfWNVLv2Hl1Q1UXveazPcgMZrMs/edit?usp=sharing/")
var ss = SpreadsheetApp.openByUrl(url);
var sheet = ss.getSheetByName("Sheet1");
return insert(e,sheet);
}
function doPost(e){
var url = encodeUrl("https://docs.google.com/spreadsheets/d/1IEAHcv2n33YO9d7IbfWNVLv2Hl1Q1UXveazPcgMZrMs/edit?usp=sharing/")

return insert(e,sheet);
}
function insert(e,sheet) {

var ctime = d.toLocaleString();
sheet.appendRow([scannedData,ctime]);

If you need to see more code, I can attach some more. It looks basically the same as the one in the tutorial right now.
Thank you so much for your help.

The reason you were receiving the Exception: Invalid argument: URL message is because the url you were passing to the openByUrl was not in the correct format.
If you check the documentation for the openByUrl method here, you can see the accepted format of the link.
https://docs.google.com/spreadsheets/d/abc1234567/edit
In your situation, you will have to remove the part after the /edit.

i cannot receive any notification from my server

this is my class that receive data from server: it does not show notification
but if i take sendBroadcast(intent) and Intent out of try and catch blocks and make msg=null; it show notification but with empty message

i add all AndroidManifest permission all things well but it dose not show notification
I want to know. is the cod that get data from server true or not

JSON is being received in android, but it won't parse. What is my issue?

As title suggests, here is the format of the JSON:
http://prntscr.com/elb4fz. Now I'm not sure if I have the parse method working properly as I think that SearchResults is the array and it'll show each individual result as an object.
I have my networkutils code as such:
package companionsdirect.practice;
import android.util.Log;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import java.io.ByteArrayOutputStream;
import java.io.IOException;

import java.net.HttpURLConnection;
import java.net.URL;
import java.util.ArrayList;
import java.util.List;
/**

*/
public class NetworkingUtil {
private static final String TAG = "NetworkUtils";
List<Product> items = new ArrayList<>();
public byte[] getUrlBytes(String urlSpec) throws IOException {
URL url = new URL(urlSpec);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
try {
ByteArrayOutputStream out = new ByteArrayOutputStream();
InputStream in = connection.getInputStream();
if(connection.getResponseCode() != HttpURLConnection.HTTP_OK) {
throw new IOException(connection.getResponseMessage() +
": with " + urlSpec);
}
int bytesRead = 0;
byte[] buffer = new byte[1024];
while ((bytesRead = in.read(buffer)) > 0) {
out.write(buffer, 0, bytesRead);
}
out.close();
return out.toByteArray();
} finally {
connection.disconnect();
}
}
public String getUrlString(String urlSpec) throws IOException {
return new String(getUrlBytes(urlSpec));
}
public List<Product> fetchItems(String url) {
try {
String jsonString = getUrlString(url);
Log.i(TAG, "Received JSON: " + jsonString);
JSONObject jsonBody = new JSONObject(jsonString);
parseItems(items, jsonBody);
} catch (IOException ioe) {
Log.i(TAG, "Failed to fetch items", ioe);
} catch (JSONException je) {
Log.e(TAG, "Failed to parse JSON", je);
}
return items;
}
public List<Product> getProdList() {
return items;
}
private void parseItems(List<Product> items, JSONObject jsonBody) throws IOException, JSONException {
//JSONObject reviewItem = jsonBody.getJSONObject();
JSONArray reviewArray = jsonBody.getJSONArray("SearchResults");
for(int i = 0;i<reviewArray.length();i++) {
JSONObject reviewItem = reviewArray.getJSONObject(i);
Product currentProductReview = new Product();
currentProductReview.setmSummary(reviewItem.getString("Summary"));
currentProductReview.setmTitle(reviewItem.getString("Title"));
currentProductReview.setmRecordType(reviewItem.getString("RecordType"));
items.add(currentProductReview);
}
}
}
And this is the activity with the asynctask:

import java.util.ArrayList;
import java.util.List;
public class ReturnReviewsActivity extends AppCompatActivity {
public String builtURL;
List<Product> prodList;
private static final String TAG = "ReturnReviewsActivity";
private TextView tv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_return_reviews);
Intent intent = getIntent();
String url = intent.getStringExtra(MainActivity.EXTRA_MSG);
prodList = new ArrayList<Product>();
builtURL = url;
new FetchItemsTask().execute();
tv = (TextView) findViewById(R.id.tv);
for(Product x : prodList) {
tv.setText(x.getmTitle() + " " + x.getRating() + " \n");
}
}
private class FetchItemsTask extends AsyncTask<Void, Void, Void> {
private List<Product> list;
#Override
protected Void doInBackground(Void... params) {
NetworkingUtil productData = new NetworkingUtil();
list = productData.fetchItems(builtURL);
return null;
}
}
}
What gives? The log shows that the json is being received,but I try to set the textview to whatever is in the list and nothing shows.

Try this
tv = (TextView) findViewById(R.id.tv);
for(Product x : prodList) {
//append the text view
tv.append(x.getmTitle() + " " + x.getRating() + " \n");
}

How to handle - Application has stopped working in Android

So I am trying to create an Android app which basically reads out the twitter feed according to the search query inside a UI. The feed that I need to display form the parsed JSON is the user name, handle, profile picture and the tweet.
Now I have created the whole thing and my code compiles but as soon as I run it the app opens and I write something in the search feed and hit enter - " Unfortunately, AppName has stopped working " I am attaching my logcat and my source code for reference.
*Solved the issue by removing set text from DoInBackground and then giving adequate permission for Android to access internet. The issue now is that as I try and display the profile picture, the URL gets displayed, not the image.

You can't call view functions like setText on another thread like an AsyncTask doInBackground function. You need to do it in onPostExecute.
