I'm trying to consume an OData API using the odata4j library for Android but keep getting an error. The example I'm using is in their page: http://odata4j.org/

I installed the odata4j library (odata4j-dist-0.7.0-clientbundle) on my Android project and ran:

import org.odata4j.consumer.ODataConsumer;
import org.odata4j.consumer.ODataConsumers;
import org.odata4j.core.OEntity;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        String serviceUrl = "http://services.odata.org/OData/OData.svc/";
        ODataConsumer consumer = ODataConsumers.create(serviceUrl);

        for (OEntity category : consumer.getEntities("Categories").execute()) {
            String categoryName = category.getProperty("Name", String.class).getValue();
            System.out.println("Category name: " + categoryName);
        }
    }
}

This is my log (since the body is limited to 30000 characters, I can't had the all log) :

  • I see `android.os.NetworkOnMainThreadException` which means you should read: https://stackoverflow.com/q/6343166/295004 but with the small section of code and cut-off error message it could be something else. – Morrison Chang Jun 07 '18 at 07:12
  • @MorrisonChang that code is all I have since is the example. I can post all the log if you think it may help. I'll check that question anyway, thank you! – Nelson Silva Jun 07 '18 at 07:39
  • If you don't find it to be a Network On Main Thread problem, do expand your question to include how and where your are testing your code snippet and do post the full log. See: [Which is the correct symbol to format logcat error output?](https://meta.stackexchange.com/a/269418/159081) and indent as needed. – Morrison Chang Jun 07 '18 at 07:52
  • @MorrisonChang I had some more code from my class but that is all I have, it's just a simple example to start up. About the log, I had all I could since there are limitations about the char number. – Nelson Silva Jun 07 '18 at 08:17
  • Back to the link I provided, put your code in at least a AsyncTask, I'm assuming that the `consumer.getEntities("Categories").execute()` call will attempt to do network activity which shouldn't be on UI thread. Your history shows some prior Android work so you should have encountered this before. The other issue may be that the library is 'old' and may not maintained. Found: https://code.google.com/archive/p/odata4j/source/android/source which may help or you may want to look at [Apache Olingo](https://olingo.apache.org/doc/odata4/download.html) which has a more recent release. – Morrison Chang Jun 07 '18 at 08:50
