Cannot result R.string.page_title, R.string.page_title, R.layout.main etc
I am new to Java and Android development. I am using Android Studio and learning how to parse XML data from this guide: https://developer.android.com/training/basics/network-ops/xml#analyze
I created a new class Network Activity and put all the code from the guide there.
The code from the website uses:
- R.string.page_title
- R.string.page_title
- R.string.connection_error
- R.string.xml_error
- R.layout.main
- R.id.webview
Every single one of them throws cannot find symbol variable X error.
I tried:
- Closing and opening Android Studio and/or cleaning and rebuilding
- I added
Network ActivitytoAndroidManifext.xml
- I made sure I don't
import android.R.
I followed every solution I could find online and I still have this problem.

The sample code from this guide uses these strings, for example when returning an error :
@Override
protected String doInBackground(String... urls) {
try {
return loadXmlFromNetwork(urls[0]);
} catch (IOException e) {
return getResources().getString(R.string.connection_error);
} catch (XmlPullParserException e) {
return getResources().getString(R.string.xml_error);
}
}
You need to add these values to your strings.xml file. It should be located under res/values/strings.xml and will look like this after you add the necessary values :
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">YourApp</string>
<string name="page_title">A title</string>
<string name="connection_error">Error text</string>
...
</resources>

Your main layout file should be located underres/layout/main.xml. This file must contain aWebViewwidget with the idwebview.
