Android, NetworkOnMainThreadException google drive

Question

I have problem with NetworkOnMainThreadException on Android.

I building a java app using Google API, . I work on java code as Google libs

developers.google.com/api-client-library/java/apis/drive/v2

This is my code

String code = data.getStringExtra("code");
        GoogleTokenResponse response;
        try {
            response = drive_flow.newTokenRequest(code).setRedirectUri(DRIVE_REDIRECT_URI).execute();
            GoogleCredential credential = new GoogleCredential.Builder()
            .setTransport(httpTransport)
            .setJsonFactory(jsonFactory)
            .setClientSecrets(DRIVE_CLIENT_ID, DRIVE_CLIENT_SECRET)
            .build()
            .setFromTokenResponse(response);
            //Create a new authorized API client
            drive_service = new Drive.Builder(httpTransport, jsonFactory, credential).build();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } //catch (NetworkOnMainThreadException e){

        //}

(When i catch NetworkOnMainThreadException drive_service will be null)

My app run on AVD Platform 2.3.3 very good, but on 4.1.1 (on genymotion) it not work.

This is logcat:

Answer 1

Wrap this code :

    try {
        response = drive_flow.newTokenRequest(code).setRedirectUri(DRIVE_REDIRECT_URI).execute();
        GoogleCredential credential = new GoogleCredential.Builder()
        .setTransport(httpTransport)
        .setJsonFactory(jsonFactory)
        .setClientSecrets(DRIVE_CLIENT_ID, DRIVE_CLIENT_SECRET)
        .build()
        .setFromTokenResponse(response);
        //Create a new authorized API client
        drive_service = new Drive.Builder(httpTransport, jsonFactory, credential).build();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } //catch (NetworkOnMainThreadException e){

Inside a Thread or AsyncTask

Answer 2

Use this code in your Oncreate() Method

 StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
 .detectAll()
 .penaltyLog()
 .build();
 StrictMode.setThreadPolicy(policy);

or Use your Http calling inside AsyncTask.
