Android Honeycomb: NetworkOnMainThreadException even when using AsyncTask and no strict mode?

问题

I run into a NetworkOnMainThreadException with my Android 3.0 app. Searching for a solution I found this, but if I understand this correctly, default setting would be that the strict mode is turned off.

Also, all my network access is in an AsyncTask, so I don't see the point in this Exception anyway.

So, I'm quite desperate now what I should do to prevent this...

Kind regards, jellyfish

Edit:

This blog entry says that AsyncTask should be enough, but at least clarifies the StrictMode point.

Solution:

I turned off the StrictMode (its probably better to keep some settings but I couldn't be bothered...):

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

After that, I did run into a "java.lang.RuntimeException: This thread forbids HTTP requests", but found a solution for this here. I'm a bit confused, though, as AndroidHttpClient worked fine when I used it in my Android 2.0+ app...

Solution, part2

As it turned out, using AsyncTask was a nice idea but pretty useless if done wrong... So there was nothing wrong with the strict mode's reaction. Should have listened, er? ;)

Still good to know it's activated on Honeycomb by default.

回答1:

StrictMode is turned on by default in Honeycomb.

See say link specifically penaltyDeathOnNetwork(). I ran into a similar problem.

回答2:

In Android Honeycomb StrictMode is enabled, turn it off adding the code on the onCreate() function...

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState); 
        setContentView(R.layout.main);       
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
    }
