[android-developers] Re: onSaveInstanceState problem while making oAuth request
It sounds like the best solution for you is to bundle the row id in your intent's "extras" and then get it back during the callback. Check out http://developer.android.com/reference/android/content/Intent.html#putExtra(java.lang.String,%20int) and http://developer.android.com/reference/android/content/Intent.html#getIntExtra(java.lang.String,%20int) On Dec 12, 12:14 am, bobetko wrote: > In my app at some point I am making oAuth request to authorize user > with Twitter.

[android-developers] Re: onSaveInstanceState problem while making oAuth request
I think the approach you want to take here would be bundling 'extra's with your intent that you can read during the callback. Check out http://developer.android.com/reference/android/content/Intent.html#putExtra(java.lang.String,%20int) and http://developer.android.com/reference/android/content/Intent.html#getIntExtra(java.lang.String,%20int) for storing a rowid On Dec 12, 12:14 am, bobetko wrote: > In my app at some point I am making oAuth request to authorize user > with Twitter.

Re: [android-developers] Re: onSaveInstanceState problem while making oAuth request
It is unlikely this has anything to do with saving and restoring instance
state, unless a configuration change is happening or your process is being
killed in the background.
If you are saying that you are seeing onCreate() called, then again I think
you should consider that you actually have a new instance of the activity
being started, and look at the logcat output if there is a log about
starting an activity.

[android-developers] Re: onSaveInstanceState problem while making oAuth request
Sorry. Yes. You are right. onCreate runs first, then onResume next. (I
am still learning about Android activity cycle :-)
Here is my onResume method that handle this data that comes from
Twitter.
See lines 5 and 6. If 6 is true I am extracting token and secret and
saving them to SharedPreferences. This code runs fine, just that RowID
variable gets lost in the process. onCreate that runs before this one
(onResume), has no idea about RowID.
@Override
protected void onResume() {
super.onResume();
Log.d(TAG, "mRowID onResume : " + mRowId);
Uri uri = this.getIntent().getData();
if (uri != null && uri.toString().startsWith(CALLBACK_URL)) {
SessionPilot appState =
((SessionPilot)getApplicationContext());
consumer = appState.getConsumer();
provider = appState.getProvider();
String verifier =
uri.getQueryParameter(oauth.signpost.OAuth.OAUTH_VERIFIER);
try {
provider.retrieveAccessToken(consumer, verifier);
Utils.StoreStringToPrefs("twitterToken",
consumer.getToken(), PREF_FILE_NAME ,this);
Utils.StoreStringToPrefs("twitterSecret",
consumer.getTokenSecret(), PREF_FILE_NAME ,this);
} catch (Exception e) {
Log.e(APP, e.getMessage());
}
}
}

Re: [android-developers] Re: onSaveInstanceState problem while making oAuth request
"onResume runs first then onCreate" -- that is not typical. Either your
activity is being restarted (due to a configuration change) or you have a
new instance created.
Also what do you mean by "Twitter sends Intent (with token and secret) back
to my activity"? Do you mean it is using setResult()? Or is this doing
something else?
And do please have a look at the logcat output to see what activities are
being started.

[android-developers] Re: onSaveInstanceState problem while making oAuth request
Thanks Dianne,
I've look at logs and my app is crashing because my RowID value is
null. RowID is record ID that is needed to query sqlite database.
I could post here all my code, but I doubt it would be very useful...
I'll try explaining better with some code snippets:
This is what I execute when user push Authorize button:
consumer = new CommonsHttpOAuthConsumer(CONSUMER_KEY,
CONSUMER_SECRET);
provider = new DefaultOAuthProvider("http://twitter.com/oauth/
request_token",
"http://twitter.com/oauth/access_token";,
"http://twitter.com/oauth/authorize";);
String authUrl = provider.retrieveRequestToken(consumer,
CALLBACK_URL);
mWebView.loadUrl(authUrl);
User is presented with login and password fields and there is also
Allow button. When user pushes this Allow button, Twitter sends Intent
(with token and secret) back to my activity. I process this Intent in
onResume method. OnResume runs first, then onCreate. At this point my
RowID is lost. Nowhere in this process onSaveInstanceState was called
because of simple reason, activity is not paused, exited, screen is
not rotated, etc... So, how do I save and retrieve my RowID? Thanks.

[android-developers] Re: onSaveInstanceState problem while making oAuth request
I thought about that. But, then another question come to my mind. Why wouldn't I always use SharedPreferences to save my activity state? For example: I passed groupID and itemID values into activity. In onCreate, I save both values to SharedPreferences. Latter, when activity is restarted (for any reason: rotation, pause, was destroyed, etc.), I check Intent first, if nothing is passed, I load values from SharedPreferences. This way I woulnd't have to use onSaveInstanceState ever. Is this OK to do? Thanks a lot. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
